Scott R. Ward -- Chairman, President and Chief Executive Officer
Thank you, Jack and good afternoon, everyone. Thank you for joining us today. I am pleased to report that CSI achieved strong results in the second quarter. Consistent with the information we provided in our pre-release on January 7th, second quarter revenue grew 14.4% to $60.2 million, marking the third straight quarter of accelerating double-digit top line growth.
We delivered strong growth in our core domestic businesses and we continue to make great progress in our efforts to expand CSI through the introduction of new products and the launch of our business in international markets around the world. We were profitable in Q2, we continue to execute on our cost reduction efforts as we drive increased unit volumes and our gross margins remain solid.
Paired with a strong balance sheet and no long-term debt, we have real financial strength. We are executing on our core strategies and driving market share gains across our businesses. Our worldwide peripheral business grew 13% in Q2, powered by 19% unit growth in the core domestic peripheral atherectomy business. The strong growth and market share gains in peripheral were driven by exceptional execution in multiple areas, including market development and expansion in office-based labs, the continued adoption of the radial site of access, the execution of long-term volume-based contracts, increased case coverage, and outstanding performance by our sales and customer support teams.
Our worldwide coronary business grew 19%, with 10% growth in the core domestic business. We have sustained momentum in our domestic coronary business through the first half of fiscal 2019, with 16% growth year-over-year. The strong momentum in our coronary business is driven by the focused efforts of our dedicated coronary sales reps to drive increased adoption at our current accounts, exceptional customer support from our sales and clinical support teams, medical education programs, and a strong market response to our emerging coronary toolkit, including the new GlideAssist feature. GlideAssist really improves the deliverability of our orbital crown, allowing the treatment of patients that otherwise may not be candidates for an atherectomy procedure due to complicated anatomy.
We are also gaining momentum with the sale of PCI and PTA support products. Adding new products to support orbital atherectomy procedures is a key initiative to improve sales productivity and increase revenue from our orbital atherectomy cases. We generated over $700,000 in new revenue from the sale of balloons and wires in Q2, and we expect that to grow as we gain more access to cath labs and launch additional products like the OrbusNeich Teleport Microcatheter.
Finally, the commercial launch of orbital atherectomy in international markets also contributed to growth in our coronary and peripheral businesses. We achieved $1.6 million in revenue in Q2, driven by performance in Japan, and we are really pleased with the rapid cadence of product launches that we have achieved in Asia, the Middle East and Europe. We are collaborating with our distribution partners to facilitate the training of motivated physicians and we are excited by the strong demand for our product. In just a short period of time, CSI has trained over 50 physicians outside the United States, and we expect to train as many as 50 more by fiscal year-end.
So these are the tangible drivers that contributed to our growth thus far in fiscal 2019.
Now, let me ask Jeff Points to provide a more detailed review of our Q2 financial results. Jeff?
Jeffrey S. Points -- Chief Financial Officer
Thank you, Scott, and good afternoon everyone. As Scott mentioned, second quarter revenue of $60.2 million, represented a 14% increase compared to last year. It also represents sequential revenue growth of 7% compared to first quarter. In total, we sold over 19,000 orbital atherectomy devices during the quarter, representing a 19% increase compared to last year.
Worldwide peripheral revenue increased 13% to $44.2 million. Our worldwide peripheral units increased over 20% compared to the prior year. Strong sales of peripheral atherectomy devices in the United States were the primary driver of peripheral revenue. We experienced our strongest quarterly peripheral unit growth in nearly four years. As expected, we had a mid-single digit ASP decline. As we've demonstrated the last several quarters, we continue to maintain strong gross margins, even as we offer volume-based pricing contracts, the high volume accounts and gain market share in the fast-growing OBL segment. Worldwide peripheral revenue also included approximately $800,000 from our international distribution agreement with OrbusNeich, as we continue our launch in Asia, the Middle East and Europe.
Worldwide coronary revenue increased 19% to approximately $16 million. Domestic coronary revenues grew 13%, primarily driven by increased unit volumes. Worldwide coronary revenue also included about $800,000 in revenue from our international distribution partners, Medikit and OrbusNeich.
So in our pre-release of Q2 results, we shared revenue contribution from the US and international. I know some of you build your models this way. So to reiterate, total US revenue increased 11% to $58.6 million, domestic peripheral revenue increased 11% to $43.4 million and domestic coronary revenue increased 13% to $15.2 million. International revenue of $1.6 million was split evenly between peripheral and coronary. Hopefully breaking down the revenue sources in this manner is assisting your financial models.
In Q2, gross profit margin remained strong at 80.9%. Operating expenses of $48.3 million increased about $5 million or 11% compared to last year, but were lower than first quarter. R&D expenses associated with investments in new product development and enrollment in the ECLIPSE clinical trial increased 13%. As we've indicated previously, we plan to accelerate our investment in product and clinical initiatives to broaden our product offering, expand the use of orbital atherectomy and drive long-term value. SG&A increased 11%, due to physician training and medical education investments to support our international expansion.
We were profitable in second quarter with net income of $492,000 or $0.01 per share. Adjusted EBITDA increased to $4 million. With a cash balance of $119 million, no long-term debt and a line of credit in place for borrowings up to $40 million, we continue to maintain financial strength and flexibility. In December, we added to that flexibility by filing a shelf registration to issue up to $350 million of equity.
I will now discuss our updated annual guidance and provide some color on our fiscal third quarter. Our original fiscal '19 revenue guidance was a range of $240 million to $250 million. In our pre-announcement of second quarter results, we narrowed the range, while maintaining the midpoint. Our fiscal 2019 guidance is now as follows; revenues in the range of $243 million to $247 million, representing annual growth of 12% to 14%; gross profit of about 80%; net loss equal to 1% to 2% of revenues; and positive adjusted EBITDA. The revenue range for fiscal '19 assumes continued core domestic atherectomy revenue growth of at least 10% and at least $4.2 million from international and new products.
For the back half of fiscal '19, we anticipate quarterly sequential revenue growth of approximately 4% to 5% in both the third and fourth quarter.
That completes my prepared remarks. Rhonda will now provide commentary on our commercial developments. Rhonda?
Rhonda J. Robb -- Chief Operating Officer
Thank you, Jeff. Let's begin with the review of our domestic peripheral business. Jeff spoke to the fact that this quarter was the strongest peripheral unit growth that we have seen in nearly four years. We saw great progress from several key drivers. However, I will focus my comments first on our increased penetration in the office space lab or OBL market, and then move into coronary and international. The OBL site of service is accelerating patient access to care and driving deeper penetration in the peripheral market.
As we have discussed previously, we have found increasing success in the OBL market with long-term contracting and increased procedural support. We initiated this strategy one year ago, as we pursued an opportunity to grow the market, increase therapy penetration and help physicians treat patients with a higher burden of calcified disease at this site of service.
As OBLs we're launching, patients treated at the site of service typically had less severe forms of peripheral arterial disease, soft plaques and above-the-knee lesions. As a result, only about 20% of our peripheral business was in OBLs. However, the combination of a growing patient population, limited cath lab availability in hospitals, economics, and patient convenience has driven more patients and more complex procedures to the OBL setting.
We've executed a focused strategy on the highest volume OBLs that also perform complex procedures. And today, OBL revenue represents approximately 25% of our domestic peripheral business. The combination of a strong safety profile, ease of use, strategic contracting and exceptional procedure support, resonates with our customers. As a result, our OBL revenues in Q2 increased 12% sequentially from Q1, and increased 28% compared to last year.
It is important to note that we focus on the care of patients with complex peripheral arterial disease, who may also have critical limb ischemia. We won't compete on price. Our customers use highly specialized techniques that require a low-profile, deliverable and safe device to remove calcium from disease vessels in the leg. With the only atherectomy device that can uniquely reduce surface calcium, facilitate the fracture of deep calcium and deliver proven clinical outcomes with a primary patency rate of 81.2% at 12 months.
In addition to OBL growth, hospital volumes also continue to grow, and we are experiencing stable reimbursement and steady pricing for atherectomy in a hospital-based setting.
Overall, we continue to project peripheral market growth in the mid-to-high single-digits. Again, CSI grew 19% in units year-over-year, resulting in market share gain within both the hospital and OBL sites of service. We also continue to gain share in our coronary business with worldwide revenues growing 19%, driven by 13% domestic growth and by international revenues.
Notably, through the first half of the year, CSI's domestic coronary business has grown 16%, while domestic ASPs have remained stable. We are innovating in our core technology and adding new products to create a portfolio of devices that allow physicians to quickly access coronary lesions, remove calcium, and prepare the vessel for stent placement
The key components of our coronary toolkit are the Diamondback system with GlideAssist, the 1 millimeter Sapphire angioplasty balloon, and now the new Teleport Microcatheter that launched in late December. This catheter is an important complement to the CSI portfolio in both the complex coronary and peripheral patient populations. We look forward to building on this momentum when we introduce the new ViperWire Advance FlexTip to physicians in the US in Q3. When combined with the GlideAssist feature, physicians will be able to more easily track the OAS device through torturous coronary vessels and effectively modify a calcified lesion to facilitate stent deployment. The safe and rapid access to calcified coronary lesions will expand the market for coronary atherectomy and further increase our market share.
Internationally, we are rapidly expanding our presence by targeting high-volume centers that are already treating complex coronary and peripheral patients. At the end of December, we've trained 50 physicians in Japan, Asia, Europe and the Middle East. Physicians in these markets are eagerly awaiting access to our technology motivated to learn and are rapidly putting their training on orbital atherectomy into their everyday practice.
As you saw in our release, we recently received approval for both our Diamondback Classic Crown with GlideAssist and the ViperWire with FlexTip in Japan. These will launch in February and we expect to continue to increase our share position in Japan. In less than one year since we launched in Japan, we are successfully executing our international expansion plan in many geographies with terrific results. Of note, we are currently seeking European CE Mark for coronary and we expect that approval later this fiscal year.
Combined with our strong domestic results, our consolidated Q2 commercial revenues through the first half position us to more than double our annual growth rate from less than 6% in fiscal 2018 to a range of 12% to 14% this year. In our second half of the year, incremental growth drivers will consist of continued progress in international, particularly with the launch of Coronary Classic in Japan; new product launches that will support at least 10% growth in our core business. These include the Teleport Microcatheter, the Coronary ViperWire Advance FlexTip, continued expansion of the peripheral radial device with a new VIPERCATH radial exchange catheter, and ViperWire FlexTip launches in Q3, as well as the launch of peripheral exchangeable with GlideAssist later in the fiscal year. GlideAssist will further assist -- further add to the market-leading clinical performance by facilitating ease of use and enabling better tracking and performance in complex lesions.
Finally, we will continue to increase the penetration of new and existing accounts through our focused sales organization, our expanding portfolio, world-class training and education, dedicated case support and long-term contracting strategies across all sites of service.
In sum, we remain very confident in our ability to achieve our near and long-term growth objectives in our core business and geographic expansion and in new innovations where we will launch more than 20 new products to expand our offering to complex coronary and peripheral patients over the next five years.
That concludes my remarks. Scott, will now provide his closing thoughts.
Scott R. Ward -- Chairman, President and Chief Executive Officer
Thank you, Rhonda. Well, as you have heard, this was really an outstanding quarter for CSI. Before I close, I want to thank our more than 700 CSI employees for their extraordinary dedication and commitment to our mission and the patients that we serve. We are driving market-leading performance with orbital atherectomy, and we are executing on our key growth initiatives to introduce new products and launch our business in new markets around the world. Our Diamondback Orbital Atherectomy System is the only atherectomy product in the market, supported by strong medical evidence that has been published in peer-reviewed journals, that demonstrates safe and effective calcium removal, vessel preparation and improve patient outcomes.
Indeed CSI is a leader in medical evidence, developing a wealth of clinical data with more than 5,000 patients enrolled in controlled clinical trials, over 8,000 lesions studied, and 600 physicians participating in our coronary and peripheral clinical research programs around the world. Our core competitive advantage is that we offer the best interventional solution for the treatment of calcium in the vasculature. We are introducing new products for the treatment of complex cases. We have the strongest medical evidence in the market. We offer superior training and education to the medical community. We are extending our global reach through our distribution partners, and we have a US sales channel composed of 200 sales professionals and 100 clinical specialists, who focus solely on supporting physicians in the treatment of calcified coronary and peripheral lesions.
This is a powerful combination that differentiates CSI and establishes a strong foundation for continued market leadership and growth in the quarters and years ahead. We are well positioned to sustain the strong growth that we have achieved in the first half of fiscal 2019, and we look to the future with confidence and a clear focus on our mission to save limbs and save lives every day.
Thank you for your continued interest in CSI. We look forward to updating you on our progress in the coming quarter and we will now take your questions. Operator, if you would, please repeat the instructions. Thank you.
Questions and Answers:
Operator
(Operator Instructions) Your first question comes from the line of Mathew Blackman with Stifel. Your line is open.
Mathew Blackman -- Stifel -- Analyst
Good afternoon, everyone. Thanks for taking the question or questions. Scott, let me start with you, are you seeing any changes in customer behavior since the publication of the Paclitaxel meta-analysis in December and what are you hearing from clinicians about the potential impact on peripheral intervention volumes broadly, but atherectomy specifically? And then I have a few follow-ups.
Scott R. Ward -- Chairman, President and Chief Executive Officer
Yeah. Thanks Matt. Clearly that has been a interesting development in the marketplace. I think it is still early days. Frankly, we haven't seen too much influence in our marketplace. We think that the potential impact at this point is probably neutral. And you know at this stage, we're we're just monitoring the drug-coated balloon company's response to this meta-analysis that's been published. And like everybody else, we're just continuing to -- to watch the results. I would say our customers are measured in their response. And at this point, we really haven't seen much change. So that's about all I have to report on that.
Mathew Blackman -- Stifel -- Analyst
Okay. Appreciate that. And then, Jeff, just a couple for you. I just want to make sure I'm capturing your third and fourth quarter commentary correctly, the 4% to 5% sequential growth, so that implies for the third quarter something in the neighborhood of $62 million to $63 million and roughly $65 million to $66 million in fourth quarter. Am I -- am I capturing that correctly?
Jeffrey S. Points -- Chief Financial Officer
Yeah. That's correct Matt.
Mathew Blackman -- Stifel -- Analyst
Okay. And then this is a bit of a long-winded question for you, Jeff. Just curious how far along are you in the price volume contracting initiatives in the OBL. Is there a way to quantify what percent of your OBL business is now contracted? I guess what I'm really trying to get at is, it's -- it's possible that in the next two, three, four quarters, you anniversary some of the multi-year contracts you signed in that pricing in that segment could potentially be modestly less negative than recent trend.
Scott R. Ward -- Chairman, President and Chief Executive Officer
Hey, Matt, this is Scott. I think in terms of the our contracting strategy, it is pretty important to just remind you that we actually don't cut contracts with that many OBL centers. As Rhonda had said in her remarks, we really focus on OBL accounts that also focus on the treatment of complex peripheral lesions. So these are typically physicians that formerly were in an hospital setting. They treat CLI patients, they treat complex peripheral lesions, they now have moved to the OBL setting. We now are supporting them in that setting and we are executing not only these long-term contracts with them, but we're providing strong clinical support to assist them with these procedures. So you know even though it has been a very, very effective strategy for us, we don't necessarily see it as something that would be implemented for example, across a broad swath of the OBL market segment.
Mathew Blackman -- Stifel -- Analyst
Okay. Understood.
Jeffrey S. Points -- Chief Financial Officer
Yeah. Matt, one thing I would add is that we have been able to take on several new accounts and really add to our market share in the OBL space by, you know, by that strategy. And so that's been really effective and really helped drive our 28% growth in the OBL segment.
Mathew Blackman -- Stifel -- Analyst
Got it. I appreciate it. I'll get back in queue. Thanks so much.
Scott R. Ward -- Chairman, President and Chief Executive Officer
Thanks.
Jeffrey S. Points -- Chief Financial Officer
Thanks, Matt.
Operator
Your next question comes from the line of Danielle Antalffy with SBB Leerink. Your line is open.
Danielle Antalffy -- Leerink Partners -- Analyst
Hey, good afternoon everyone. Thanks so much for taking the question. Just wanted to follow up on Matt's question regarding the Paclitaxel meta-analysis. I appreciate that you expect it to be neutral, but just wanted to dig a little deeper. I mean, my one concern is that it could impact overall referral volumes from referring cardiologists to peripheral -- for peripheral intervention. Just curious about what you're hearing around that. Then I have one follow up.
Scott R. Ward -- Chairman, President and Chief Executive Officer
That's a fair question Danielle, and thank you for that. I -- at this point in time, the feedback that we are receiving is that it really is not having much impact on referral -- the referral base. Clearly, it's something we'll continue to monitor. We have not at this stage seen any impact from that. We're watching it closely, but right now I can -- I can report that the referral channels and the system continues to be working as -- as it has in the past.
Danielle Antalffy -- Leerink Partners -- Analyst
Okay, great. And then my follow-up is probably for Rhonda. So you gave some details on what the drivers were for peripheral growth in the quarter, but wondering if you could give a little bit more color. I mean, this -- it was your strongest -- I think you said the strongest peripheral growth quarter in four years, which is amazing. So just trying to get a sense of the driver, how much of that you think gives you access like radial, new products, shifting to OBL. Obviously price is a headwind. So just trying to get a sense of what the different drivers are and how big each of those drivers are to that growth? Thanks so much.
Rhonda J. Robb -- Chief Operating Officer
Yeah. Thanks, Danielle. Appreciate the question. It was obviously a spectacular quarter and we continue to see -- I think the biggest thing is, we're seeing office space labs actually have an impact on the number of patients being treated. So it's actually improving penetration in the peripheral market. Hospital volumes also continue to grow. So that -- that I think is a really exciting development. So there's strong market development happening in the space. There is continued adoption of the radial site of access and particularly as we come out with some of the new tools in Q3, Q4, we expect that to continue. A big driver really has been the execution of the long-term volume-based contracts. And you can see that in the numbers, (inaudible) growth 28%, is really spectacular, so I would say that's one of the most significant drivers.
But we've also increased our sales coverage and case coverage. And the expansion of the clinical specialists has really given us the level of focus that really differentiates CSI and that's just been outstanding performance by our sales and customer support teams. So I think it's a combination of all of those things that really has made CSI distinct in terms of winning in the OBL setting.
Danielle Antalffy -- Leerink Partners -- Analyst
Hey, thanks so much.

Your next question comes from the line of Margaret Kaczor with William Blair. Your line is open.
Brandon -- William Blair -- Analyst
Hi, this is actually Brandon (ph) in for Margaret. Thanks for taking the question. First, I just wanted to focus on, I know one of the things you've been focused on is kind of going deeper into your current accounts. And -- can you just talk about success you've had in doing that so far? And really, just do you think success there is more of a function of having a broader portfolio or do you think that there's just an increased interest in vessel prep and that's kind of helping drive core business? And I have one other question. Thanks.
Scott R. Ward -- Chairman, President and Chief Executive Officer
Yes, so I think it's a little bit of a different question, depending on whether we're talking about peripheral and hospital or coronary. It's certainly in the case of peripheral. We do see continued adoption there. As more and more physicians utilize our product and achieve strong outcomes, we have increased demand for participation in our medical education programs. Last quarter, we conducted almost 50 medical education programs and we have very strong attendance at those programs, we have very strong demand to participate in those programs, and generally, the participants are physicians who are coming from existing accounts who have had peer-to-peer training from one of their colleagues where they're at the location where they're coming from. So that has really been an important driver for us. And I think that continues to really increase the number of physicians that have been trained and educated.
In the case of coronary, I think that the continued focus there on these complex coronary lesions, and the continued focus of the medical community on treating these patients has really continued to have a beneficial impact for us. And what we find there is that the fellows training that we're conducting, I think in first and second quarter, I think we certified over 30 new fellows, most of which were in the coronary space. And there, we really see a strong adoption related to this commitment to improve the quality of care for patients that have complex coronary lesions. So I think overall, that gives you some idea. I think this is really driven by local demand and the other thing I guess, I would emphasize in coronary that has really made an important difference, is our introduction of GlideAssist, and you've heard me talk about that for a couple of quarters. But GlideAssist is a new feature that we have in our Diamondback system that makes this device really deliverable. And it helps physicians deliver the crown of our device through really angulated and tight lesions. And as a result now, physicians who are using it routinely are gaining increased confidence that they can reach lesions that are deep and that have formerly been difficult to get to.
I made a really important comment there and that is confidence. GlideAssist gives physicians confidence to access these lesions and as a result that's why they will choose orbital atherectomy first. So when they look at their case, they'll do their case planning and they'll decide from the outset that they're going to use orbital atherectomy and try to access that lesion. So I think Diamondback has had a really important impact and it will continue to as we move forward. But those are I think the primary drivers for our increased adoption at our current sites.
Brandon -- William Blair -- Analyst
Great. That's very helpful. Thanks. And if I could just switch internationally, there's a lot of exciting things going on in a lot of different international regions and countries. It's my understanding that CSI is going to be responsible for the training and support on the ground. Can you just talk about how -- how comfortable you guys are with making sure you're not stretched too thin across too many geographies at once and if you need to make any meaningful investments in those regions in the coming quarters. Thank you.
Scott R. Ward -- Chairman, President and Chief Executive Officer
Yeah. Thanks Brendan, and I appreciate that question. You're absolutely right. We have experienced very strong demand outside the United States. Just to be clear OrbusNeich, our partner in markets other than Japan, is responsible for sales, physical distribution and support of customers. Our organization is responsible for medical education and training those customers. So we will train them and bring them up, but once they're up and running, OrbusNeich will continue to support them in the future.
Now what we have seen is, we are basically executing a peer-to-peer type training model where we will go into a particular geography, train and educate a physician, who then will work to train and educate his or her colleagues and that has proven to work very effectively for us in Japan. We're continuing to do that now in other markets around the US and that gives us some capacity in, let's say, our ability to extend our medical resources. So that has been effective. I can assure you that we're watching this very carefully and we're adding resources to our education teams as necessary.
We have had very strong demand in Asia and also for our peripheral products in the Middle East and in Europe. And naturally as you can imagine those geographies are widely spread. So we're working to kind of build our core competence in each of those areas and really assure that we have the people on the ground that can support our customers. We are firmly committed to assuring that our customers achieve great outcomes with the use of our products no matter where in the world they're used. So, we will continue to invest in medical education and training to support these physicians in both coronary and peripheral procedures. So I hope that answers your question. Other questions on that? No -- we lost Brandon?
Brandon -- William Blair -- Analyst
No, that was great. Thank you.
Scott R. Ward -- Chairman, President and Chief Executive Officer
Okay. Thanks Brandon.
Operator
Your next question comes from the line of Bob Hopkins with Bank of America. Your line is open.
Bob Hopkins -- Bank of America Merrill Lynch -- Analyst
Thanks, and good afternoon. Just a couple of quick ones. I was intrigued by the comments on OBL and the growth in OBL, the 28% number. Just -- can you just give me a quick sense as to the contribution from pricing to that 28%?
Scott R. Ward -- Chairman, President and Chief Executive Officer
It's actually hard to spice that out, Bob. As you recall about -- it was in August of last year that we added a significant number of clinical specialists. We also, at that time, began rolling out some of these long-term contracts to our larger accounts. And what we see is that the combination of those two, along with the fact that we have the only device that can be used to treat severe calcium in the vasculature, those three things combined have really led to great success in the OBL. I think this is more about focus and really focused execution by our sales and clinical support teams than it is about pricing. We do have -- we are establishing these long-term contracts, and I guess, that's how I would approach it. Jeff, do you have anything you would add to that in terms of...
Jeffrey S. Points -- Chief Financial Officer
No, the only thing I think I would add Bob is, that the pricing and contracting strategy has really allowed us to get into some of these labs and actually on the ASP erosion, specifically within labs, it's actually gotten more favorable this quarter. So that's been a great sign of stability and has helped us drive that revenue.
Bob Hopkins -- Bank of America Merrill Lynch -- Analyst
Okay. So just roughly then of the 28 points of growth, it's probably not much more than a couple points of that, that's being driven by price. Is that fair?
Scott R. Ward -- Chairman, President and Chief Executive Officer
No. Like I said Bob, I just -- we just don't know. We just don't differentiate it in that way. As you can imagine, we have simultaneously launched multiple initiatives that focus on the OBL segment. And I think what I can say at this point is, I'm really pleased that in total, they are working very effectively.
Bob Hopkins -- Bank of America Merrill Lynch -- Analyst
Got it. And I'm just curious, this might be simple math. So I'm sure I could do it offline. But if OBL is growing 28%, the kind of revenue growth in the rest of the peripheral business is probably mid-single digit? I mean, basically is there anything tricky about the math I'm trying to do?
Jeffrey S. Points -- Chief Financial Officer
Bob, this is Jeff. No, there's not. I mean, we continue to grow kind of that mid-to-high single-digit in the hospital, and grew 28% in the OBL. So if you pro-rata that, you get to the 11% -- roughly the 11% growth rate in the US.
Bob Hopkins -- Bank of America Merrill Lynch -- Analyst
Okay.
Scott R. Ward -- Chairman, President and Chief Executive Officer
Yes, the only thing I would just add, Bob, we are really pleased, I mean our hospital segment has also continued to grow well. So that's why you see this large growth in peripheral and the real strength that we have there. I mean clearly, we're gaining market share every day in our peripheral segment and we're really, really happy about that. We're doing that both in the hospital portion and in the OBL. So right now, I think we're really hitting on all cylinders in peripheral.
Bob Hopkins -- Bank of America Merrill Lynch -- Analyst
And then one last question. If you look at the guidance and then the revenue generated in the first half versus what you need to generate in the back half, obviously, there's a -- there's some acceleration in growth assumed there. It's roughly $10 million to $12 million of incremental revenue in the back half. So maybe if you wouldn't mind, just kind of break it down for us, what are the biggest buckets that drive that incremental growth or incremental $12 million that you need in the back half?
Rhonda J. Robb -- Chief Operating Officer
Hey, Bob, this is Rhonda. I'll take that. I think the first and largest one will be the new product launches and we said it will support at least 10% growth in our core. So we have a number of new things coming that will continue to complement our coronary and peripheral portfolios, and I mentioned a few of those, we're really excited about, the Microcatheter, Advance FlexTip with that, in combination with GlideAssist really kind of rounds out this coronary toolkit that we think is going to give us access to even more cases in the coronary setting. And then we also talked about the continued expansion of the peripheral portfolio as well.
So we have -- we have a lot happening that's pretty exciting in the back half of the year with regard to new products that are going to support that core business. I think in addition to that, it's just continued focus of our resources, as we articulated earlier. In terms of our sales organization, the volume-based contracting that will continue in OBL, but also as I said earlier, extend to the hospital-based setting as well for both peripheral and coronary. And then the last one is, is continued progress in international. And we mentioned that the launch of Coronary Classic will occur in Japan. So that will continue to be a driver within Japan, as well as extension into other geographies as well. So it's really those three things.
Bob Hopkins -- Bank of America Merrill Lynch -- Analyst

Your next question comes from the line of David Saxon with Needham & Company. Your line is open.
David Saxon -- Needham & Company -- Analyst
Hi. Good afternoon, and thanks for taking the questions. First, I was just wondering if you've seen any changes in the competitive landscape, particularly from companies like Shockwave or Ra Medical. And then also, I mean, if you've seen any impact from the Eluvia drug-eluting stent?
Scott R. Ward -- Chairman, President and Chief Executive Officer
So in terms of the two companies that you referenced, no, we really haven't. I guess, as you could tell, we gained significant market share in second quarter. Both of those companies I think participate in the peripheral segment, but are not present in the coronary segment. And you saw the very large unit growth that we had in peripheral and really the strong performance that we had in United States. So we really don't see either of those companies in our segment and perhaps that's because they focus on the patient population that has a little lighter disease burden. Remember, we partner with physicians who treat really complex cases and we have a very unique position there, and we've enjoyed success in that segment for many years and you can tell that has continued this past quarter. So your second question was regarding drug-eluting stents?
David Saxon -- Needham & Company -- Analyst
The Eluvia. Yes.
Scott R. Ward -- Chairman, President and Chief Executive Officer
Oh, the Eluvia?
Rhonda J. Robb -- Chief Operating Officer
Yes.
Scott R. Ward -- Chairman, President and Chief Executive Officer
No. So Eluvia, I think in terms of the -- the launch of Eluvia, it's a very intriguing product and I think physicians -- it's received a positive response from the medical community. But we don't really necessarily see that as a driver to increase adoption for drug-eluting stents. We do think that it'll gain share. But to say how much I don't know. But right now, Eluvia has not had a really a direct impact on our business. The one thing that I would say is, it is encouraging to see companies successfully develop, get PMA approvals for these products, and bring them forward because really anything that drives patients to cath labs, helps us because when patients arrive at cath labs and they have severe calcium, our product is used.
David Saxon -- Needham & Company -- Analyst
Okay that's helpful. And then, I'm just looking at the balance sheet. I mean you have a pretty healthy cash balance and you filed for shelf. Just wondering what you're thinking there and do you have any M&A aspirations?
Jeffrey S. Points -- Chief Financial Officer
Yes, really that just gives us flexibility. It's just -- we look at it as a matter of good housekeeping. And we think that's a pretty standard thing that other companies in the industry put out there. There's nothing imminent that is being planned, it's just something that we think we would -- thought would be important to get into place.
David Saxon -- Needham & Company -- Analyst
Okay.
Scott R. Ward -- Chairman, President and Chief Executive Officer
In terms of cash, we do -- we like to have a nice strong, stable balance sheet. And so we're pleased with that cash position, and that makes us a bit unusual perhaps and -- in terms of small cap medtech companies. But I enjoy that position having a good, strong stable balance sheet.
David Saxon -- Needham & Company -- Analyst
Yeah. Well, fair enough. Well, thank you very much. Take care.
Scott R. Ward -- Chairman, President and Chief Executive Officer
Thanks.

Your next question comes from the line of Brooks O'Neil with Lake Street Capital. Your line is open.
Brooks O'Neil -- Lake Street Capital Markets -- Analyst
Thank you. Good afternoon, and congratulations on the progress you guys are making.
Scott R. Ward -- Chairman, President and Chief Executive Officer
Thanks, Brooks.
Brooks O'Neil -- Lake Street Capital Markets -- Analyst
Thank you, Scott. At the Investor Meeting this summer, a lot of the focus was on the significant ramp up in spending for new product development. Obviously, you've got a lot that you've already talked about. But are there some developments that you have made in terms of progress with new products that are kind of behind the scenes?
Scott R. Ward -- Chairman, President and Chief Executive Officer
Brooks, it's a great question and we will continue to provide updates on our -- our key growth drivers over time as it becomes appropriate. You know a lot of those projects now are in the design stage and as they move from one stage to the next, we will certainly let you know about it. So you know the next key events coming up would be the completion of Phase I testing, completion of animal testing and moving forward with IDEs let's say, for our -- our vascular laser, as well as our mechanical circulatory support pump. So at this stage both of those projects continue to make strong progress. They're right on plan, but they are obviously in the early stages of development. So I hope that answers your question.
Brooks O'Neil -- Lake Street Capital Markets -- Analyst
Yes, that's fine. Secondly obviously, some -- some conversation about progress internationally. I was hoping you could just talk a little bit about how significant you think the international opportunity is, how significant do you think the opportunity working with OrbusNeich is for CSI now?
Scott R. Ward -- Chairman, President and Chief Executive Officer
So OrbusNeich has been a terrific partner and we've really been impressed with their motivation and the way that they have approached this marketplace. They have really rapidly moved forward and that is something we -- we developed a relationship. We know OrbusNeich very well because, of course, we distribute their products in United States; they distribute ours outside of the United States. And we've really been pleased with how rapidly they have launched our products. And not only that, but where they've launched, we've had very significant uptake and we've had strong case volumes. So we're we're very -- we're very excited about our international launch and pleased that at this point in time, it's kind of right on schedule maybe, it's even a little bit ahead of schedule of where we thought it might be. In terms of the long-term potential for international, yes...
Jeffrey S. Points -- Chief Financial Officer
So what we announced in July was fiscal '23 goal of $25 million to $50 million in international, that would still be a good estimate to go with, Brooks.
Brooks O'Neil -- Lake Street Capital Markets -- Analyst
Okay, Jeff. Thanks a lot and congratulations getting on the progress.
Scott R. Ward -- Chairman, President and Chief Executive Officer
Yeah. Thanks.

Your final question comes from the line of Jayson Bedford with Raymond James. Your line is open.
Jayson Bedford -- Raymond James & Associates -- Analyst
Thanks and good afternoon. Just, I guess, a few quick ones. While we're on international, I want to ask on peripheral. What markets are you and OrbusNeich targeting right now and can you maybe just talk about the reimbursement environment in those countries?
Scott R. Ward -- Chairman, President and Chief Executive Officer
Yeah, sure. So thanks Jayson. Right now as I indicated earlier, I mean we're in Asia, we're in the Middle East and in Europe for peripheral. Now in Asia and the Middle East, we have focused on a -- really a number of different company -- countries where there is favorable local payment oftentimes cash pay. These are environments that have already adopted the use of interventional procedures for the treatment of peripheral vascular disease.
So we are not engaging in new market development. We're not developed -- we're not working with customers, let's say, who need to develop referral channels or have a past history of reimbursement issues. We're working with institutions in centers that have already got well-established practices. We're basically coming in and taking market share based upon the strength and the superiority of our technology. As a result, right now, we have not really had reimbursement issues. I think as we continue to grow over time, reimbursement can become a barrier, as you know, and you and I've talked about this before, I'm always paranoid about reimbursement. But right now, we feel pretty confident that the business model that we offer, the value proposition that we offer, is favorable in many of these markets. And what I mean by that is, oftentimes if physicians will choose to use orbital atherectomy first, they can do more cases in a day. So as a result, a lot of times the value proposition for the use of our product is captured at the cath lab level, because the cath lab does much better in total revenue, total business, total number of patients cared for, if they can treat more patients every day. And using our technology enables them to not only provide a safe and effective treatment, but also to do it more quickly and efficiently.
Jayson Bedford -- Raymond James & Associates -- Analyst
Scott, you mentioned taking share. Are you displacing another atherectomy device in these countries or is it just additive to the procedure?
Scott R. Ward -- Chairman, President and Chief Executive Officer
It's hard to say, I would say in many cases, we are displacing other devices. Like I said, we're generally going to well-established clinics and sites. We're not developing new locations. So this isn't market development. In a market like Japan where we're using orbital atherectomy for the treatment of coronary arterial disease, there I would say, it's probably both where the use of our device in combination with GlideAssist is expanding the market and the use of our technology makes it more attractive to use atherectomy and to really do the vessel preparation that's required for stent placement. So in a place like Japan, I would say we're expanding the market, but most of the rest of the world we're probably displacing balloons, which is either cutting balloons or a POBA, is really the standard of care in most of these markets. And so that's where I would say we're taking that market share from.
Jayson Bedford -- Raymond James & Associates -- Analyst
Okay. That's helpful. And then just back to the US peripheral market. 19% unit growth is a pretty big number, especially given your share. I know you mentioned that you think the market is growing kind of mid-to-high single-digits. But do you have any data points that make you think the market grew a little bit faster here in the December quarter?
Scott R. Ward -- Chairman, President and Chief Executive Officer
Actually, the only data point we have comes from the analyst community and some analysts have suggested that the market grew slower, that it only -- that there was only a 5% increase in peripheral procedures. That seems a bit low to us, but that's really the only data point we have right now. Historically, if you look at this Jayson, it is a very consistent growth rate in that mid-to-high single-digits. Now we get great clarity a bit late in the process, because we have to look back one to two quarters typically, to really get clarity on what happened with market shares. And that's largely because we compete against very large established companies, who just don't report at the level of detail of their atherectomy sales. So we have that look back, we're operating admittedly off of a historical model, but nonetheless, I think you can tell that, if over time that marketplace even if it's growing in the mid-to-high single-digits, our growth rate last quarter was two times that rate or higher.
Jayson Bedford -- Raymond James & Associates -- Analyst
All right. Okay that's helpful. Thank you.
