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