In simplest terms, it was an excellent quarter for Intuitive Surgical, as the company delivered its 13th-straight quarter of double-digit sales growth or higher. On top of the figures listed above, Intuitive Surgical delivered 19% growth in da Vinci procedures outside of the United States. These international markets now account for 38% of total da Vinci volume and highlight steady adoption internationally as "expanded reimbursement coverage and policy changes in Japan and Europe" help fuel global expansion.
Elsewhere, Intuitive Surgical continues to make incremental innovations that help keep the company the leader in its niche. One example of this is its force-feedback instrumentation, which reduces tissue forces and improves surgical outcomes. President David Rosa spoke about the potential of this new instrumentation, saying, "In March, we received FDA 510(k) clearance for additional uses of our Force Feedback instruments. Five of 6 instruments are now cleared for 15 uses, while our Mega SutureCut Needle Driver is cleared for 10 uses."
Powered by innovations like these -- paired with the long-term ambition to make telesurgery (remote RAS) common -- Intuitive Surgical's growth story is far from over in my eyes. Trading at 49 times forward earnings, Intuitive Surgical commands a well-deserved premium valuation, but considering its track record of double-digit sales growth and industry-leading innovation, I'm happy to keep adding to my shares over time.
