A ventricular assist device (VAD) for use with a heart includes a housing, an upper membrane pump including a pumping chamber coupled to one-way upper inlet and outlet valves, a lower membrane pump including a pumping chamber coupled to one-way lower inlet and outlet valves, and an actuator that causes the upper membrane pump and the lower membrane pump to alternately draw blood into and pump blood out of their respective pumping chambers, and a control module in operative communication with the actuator, wherein the actuator operates with a pumping frequency which is greater than a pulse frequency of the heart.

Present disclosure discloses an implantable total artificial heart. The artificial heart includes a first pumping chamber, a second pumping chamber and an actuator disposed between the first pumping chamber and the second pumping chamber. The actuator is configured to operate between a first operating state and a second operating state. Further, the artificial heart includes a plurality of first wires wound around the first pumping chamber and the actuator, and/or a plurality of second wires wound around the second pumping chamber and the actuator. Each of the plurality of first and second wires are configured to compress the first and second pumping chambers relative to operation of the actuator for receiving fluid into and pumping fluid out of the first and second pumping chamber. The configuration of the artificial heart is compact, improves durability and mimicking the natural movement of a human tissue for reducing stress on blood and resulting in fewer side effects.
