It's been a rough year for robotic surgical system maker Intuitive Surgical (NASDAQ:ISRG). This innovative company might lead the up-and-coming robot revolution in health care, but its shares have felt the pain over the past year, falling more than 9% over that time. Between safety and cost concerns and falling system sales that have hammered the company's profit growth, Intuitive investors have struggled through a year of maladies from this health care giant.

The same goes for investors of medical device upstart Edwards Lifesciences (NYSE:EW). Edwards is another innovative up-and-comer, but the company's Sapien heart valve hasn't grown as much as Wall Street's hoped as of late. With competition from the likes of Medtronic (NYSE:MDT) and other device leaders breathing down its neck, Edwards is in need of a big leap to keep the rivals at bay.

But can either Edwards or Intuitive Surgical make the leap from struggle to surge in the near future? Find out in the video below, as Motley Fool contributor Dan Carroll takes you through what's been ailing these two health care stocks -- and which one's poised to bounce back in a big way for your portfolio.
