Medtronic: +1

FDA approved Medtronic's Evolute R TAVR system this year.

Thanks to its megamerger with Covidien, which completed early this year, Medtronic rose one spot in the top 10 rankings this year, ending up at No. 2. The Ireland-based company also won FDA approval of its Evolut R transcatheter aortic valve replacement system in June.
