TandemLife is now LivaNova! One Pump. Massive Potential. TandemLife (formerly, CardiacAssist, Inc.) exists to deliver Life Support Simplified, with one small pump enabling any type of extracorporeal circulatory support your patients may need. The TandemHeart pump was the driving force behind the world’s first percutaneous left heart support system. We’ve added on to this legacy of innovation by developing three new product lines with the same reliability you’ve come to expect; TandemLife, TandemLung, and Protek Duo.
