ABSTRACT:
A high reliability cardiac assist system is provided for permanent use. An electric motor having dual sets of coils rotates the impeller of an intraventricular axial flow pump in the preferred embodiment. The dual motor coils are powered by separate redundant battery and electronics systems configured such that if any wire breaks or if any electrical system component fails the pump will continue to run and sustain the life of the patient powered by the other electronics and battery system. High reliability pump bearings, pump structure to prevent failure due to thrombus, high reliability power cable conduits and connectors, high reliability redundant transcutaneous power transmission systems, and other sub-systems are provided which interact together in an integrated fashion to permit function for more than a decade following surgical implantation of the system without re-operation.
