  • Patent number: 4369530
    Abstract: A cardiac prosthesis having a hydraulically actuated compressible blood pump. An actuation chamber adjacent the blood pump receives pulses of hydraulic actuation fluid from an actuator pump through a fluid inlet path to compress the blood pump during systole and eject blood therefrom. Between pulses the actuation fluid is permitted to drain from the actuation chamber through an outlet path into a reservoir. Discharge of fluid through the outlet path is controlled by a dump valve which is adapted to close or open the outlet path primarily in response to forces which vary as a function of the flow of actuation fluid through the fluid inlet path.
