Hydraulically actuated cardiac prosthesis with three-way ventricular valving

摘要: A cardiac prosthesis having a hydraulically actuated compressible blood pump. An actuation chamber adjacent the pump receives hydraulic fluid from an actuator through three-way ventricular dump valve to compress during systole and eject therefrom. During diastole is permitted drain into reservoir. The includes inlet outlet manifolds synchronously movable members within each manifold for controlling flow of out chamber.
