This third generation drive system was designed to increase its reliability and ease of operation while reducing its size. The drive system controls and monitors the pneumatically driven blood pumps which are used in the total artificial heart and the ventricular assist device. The pumps consist of a rigid outer case which envelops a flexible sac and two one-way tilting disc valves that ensure unidirectional blood flow. The drive unit powers the pump with adjustable amplitude and adjustable duty cycle pulses of gas that alternately pressurize and evacuate the space between the pump case and the blood sac. It has two basic modes of operation, transport and normal or stationary.
