Clinical trial results announced at the Transcatheter Therapeutics conference in San Francisco headlined the medtech research and development news last week.

The second half of summer is usually a slow time for news about cardiac technology innovations because there are not many major conferences. But there was still plenty of innovation news coming from both small and big cardiovascular device companies in July and August.
