Abstract

A totally implantable artificial heart that utilizes a fluid displaced from the left blood pump to power the right blood pump. The left blood pump is a sac-type pump powered by an electric motor that, when contracting and expanding, displaces a volume of fluid in a fluid chamber within the left pump housing. The fluid is displaced through a fluid line connecting the right blood pump, which is a pneumatically operated sac-type or rotary-type pump. The artificial heart permits spatial separation of the left and right blood pumps within the chest of the patient for ease in implantation.
