Abstract
An apparatus adapted to be used in connection with an artificial heart assembly having a blood inlet conduit, a blood outlet conduit, and a pump that pumps blood from the blood inlet conduit to the blood outlet conduit. The apparatus includes an internal coil adapted to be implanted beneath the skin of a subject, an AC-to-DC converter that provides electric power from the internal coil to the pump, an external coil adapted to be disposed adjacent the internal coil and separated from the internal coil by the skin of a subject, the external coil being coupled to transmit electric power to the internal coil through the skin of the subject. A DC-to-AC converter is coupled to the external coil and to a source of DC power. The DC-to-AC converter selectively converts DC power from the DC power source into either a first frequency during a first period of time or a second frequency during a second period of time, the first frequency being different than the second frequency.
