ABSTRACT:
A rigid-vane artificial heart pump includes a vane shaft which extends from the gear box into the blood pumping chamber and a torsion seal for hermetically sealing the gear box from the pumping chamber so as to prevent contamination of blood. Check valves are provided to control the blood flow direction and to determine the pump's mode of operation.
