Abstract: The fluid dynamic behavior of a Newtonian water/glycerol solution, a non-Newtonian polymer (separan) solution, and bovine blood were compared in the Penn State Electrical Ventricular Assist Device ...

Abstract: A mathematical model is developed for calculating the pressures and flows in an artificial heart, its pneumatic drive unit, and a mock circulatory system. The system is divided into convenient ...

Abstract: An intracorporeal left ventricular bypass, incorporating an electrically driven roller pump, has operated successfully in unrestrained calves for periods up to 11 days. A pneumatically powered ...

Abstract: In this study we have employed a single channel, pulsed ultrasonic Doppler velocimeter to measure instantaneous velocity distributions within the pumping chamber of a ventricular assist device. ...
