Next generation total artificial heart

A total artificial heart system comprising:

• at least one artificial ventricle configured to be coupled to at least one of a pulmonary artery, a vessel of a heart, and a chamber of a heart;
• at least one drive system that comprises at least one electric motor, that is coupled to the at least one artificial ventricle, and that is configured to cause a volume of the at least one artificial ventricle to contract and expand;
• 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 the chest cavity of a patient;
• wherein the at least one electric motor comprises:
• an inner stator housing;
• a plurality of winding groups disposed radially outward of the inner stator housing;
• an outer stator housing disposed radially outward of the plurality of winding groups;
• and
