Abstract
Extracorporeal circuit devices can be used for on-pump open-heart surgery to support surgical procedures such as coronary artery bypass grafting. In some cases, a centrifugal pump is used as part of an extracorporeal circuit. Centrifugal pump heads are described herein that induce flow on two sides of an impeller plate, and that can be conveniently mechanically assembled.
