An artificial heart capable of acting as a substitute for a natural heart comprising a casing constructed of a material compatible with tissue of a living being and of a size to fit within the chest cavity of a living being after removal of the natural heart. Tube means are provided on the casing for connection to the natural blood vessels of the living being with valve means operatively associated with the tube means for controlling the flow of blood therethrough. The casing includes a pair of cavity portions capable of functioning as the two ventricles of the natural heart, with independent diaphragm means operatively associated with each cavity portion. A pressure plate is reciprocally mounted in each cavity portion and is operatively associated with the diaphragm means for effecting a pumping action of blood through the tube means and into the blood vessel in simulation of the natural heart. A single reciprocally operable solenoid means is operatively associated with the two pressure plates for simultaneously effecting operation of each pressure plate in a pumping operation. The heart is cyclically controlled by a pulser operable power pack adapted to be worn by the living being externally of the body. The power pack includes control means adapted to be connected through input supply lines to the solenoid means for controlling the cyclic rate of the pumping operation.
