  • Patent number: 4731076
    Abstract: A totally or partially implantable fluid delivery system actuated by a valveless piezoelectric drive system. The drive system may actuate an artificial heart by a hydraulic bladder or directly actuate a human heart. The drive system has an output with a frequency and displacement sufficient to directly drive a human or artificial heart and includes a control circuit for recapturing and reusing the power driving the piezoelectric drive system. An artificial heart which includes two check valves having a flexible valve element and supporting tabs on opposite sides.
