Shares of medical-device maker St. Jude Medical (NYSE:STJ) climbed more than 5.2% today after the company reported its second-quarter results. While net sales were down slightly compared to the same quarter last year, the company's revenue and earnings per share beat estimates and impressed investors.

The focus in the report was partly on improved sales in St. Jude's Cardiac Rhythm Management division. This division failed to grow year over year, but sales were far more robust that in the first quarter of this year. This might also be a good sign for other medical-device companies competing in this space. Health-care analyst Max Macaluso discusses these topics in the following video.
