Buy medical device stocks now? Even with the new tax imposed by Obamacare? Health care analyst Max Macaluso recently sat down with Fool contributor Keith Speights to talk about why buying medical device stocks actually makes sense. Keith discusses three stocks that he really likes in the medical device sector: Cynosure (CYNO), Edwards Lifesciences (EW -1.07%), and St. Jude Medical (STJ).

Cynosure makes laser systems for cosmetic applications such as hair removal and cellulite reduction. The company recently announced the acquisition of a rival: Palomar Medical Technologies (NASDAQ: PMTI).

Edwards stands out as a leader in the transcatheter heart valve market with its SAPIEN heart valves. The company also makes tissue heart valves and hemodynamic monitoring devices.

St. Jude Medical competes in several medical device markets, with products ranging from defibrillators to heart valves. The company also is a key player in the growing renal denervation system space.

In this video, Max and Keith discuss how each of these three stocks could be good investment opportunities.
