Artificial pump effectively backs up failing hearts

... The VentrAssist device pumps blood in a continuous flow in contrast to earlier heart assist pumps that pumped blood in pulses. It contains a spinning rotor that is suspended by blood within the pump housing and magnetically rotated. Since the impeller blades don't touch any part of the pump, the chance of...

WorldHeart Submits IDE Application for a Pivotal Bridge-to-Transplant Study of the Levacor(TM) VAD

Pumps Someday May Allow Patients to Recover Their Own Hearts

...fer, depending on patient need. Some provide volume displacement, meaning they squeeze blood out of the heart chambers; others operate on a high-speed rotor to provide a continuous flow of blood. The latest generation of VADs operate with magnetic levitation bearings to move blood, meaning the parts never ...
