Intuitive Surgical (NASDAQ:ISRG) has released its fourth-generation robotic surgery machine, the da Vinci Xi. It's the first new product the company has released in a couple years, and in this video from Wednesday's Stock of the Day, Motley Fool analyst Simon Erickson tells investors why he thinks it could be a major driver for the stock.

Not only is this next-generation machine easier for surgeons to use, Simon also sees the da Vinci Xi as having a flexibility of motion that will enable the device to conduct a wider range of general surgery procedures. Intuitive's machines previously were somewhat limited on what they could handle, but Simon sees this new wider range of applications as the game changer.

But is the stock a buy at these prices? Simon still thinks so. Here he discusses what he loves about the company's management and its revenue, and why he continues to see it as a buy today.
