Claim 0:
1. A total artificial heart system comprising:
at least one artificial ventricle configured to be coupled to at least one of a pulmonary artery, a blood vessel of a heart, and a chamber of a heart;
at least one drive system coupled to the at least one artificial ventricle and configured to cause a volume of the at least one artificial ventricle to contract and expand,
wherein the at least one drive system includes at least one electric motor comprising:
at least one stator assembly;
at least one rotorcam coupled to the at least one stator assembly;
at least one cam follower coupled to the at least one rotorcam;

wherein at least one artificial ventricle is coupled to the at least one cam follower,
wherein a change in height of the at least one cam follower causes an expansion of the volume of the at least one artificial ventricle, and
wherein a magnitude of said expansion is inversely proportional to a rotational speed of the at least one rotorcam;, and
at least one power supply electrically coupled to the at least one electric motor, wherein the at least one artificial ventricle and the at least one drive system are configured to be implanted in a chest cavity of a patient.
