Abstract (en)

[origin: WO9925274A1] An artificial heart design including a plurality of chambers defined by a flexible material (5) and at least one piezoelectric device (3). The piezoelectric device is activated to cause the flexible material to move between a constricted and unconstricted position. Accordingly, this results in a change in volume for the chamber causing blood to be forced from or into the chamber.
