Abstract:
An artificial heart assembly, comprising:a blood inlet conduit; a blood outlet conduit; a pump that pumps blood from said blood inlet conduit to said blood outlet conduit; an internal coil adapted to be implanted beneath the skin of a subject; an AC-to-DC converter coupled between said internal coil and said pump, said AC-to-DC converter providing electric power from said internal coil to said pump; an external coil adapted to be disposed adjacent said internal coil and separated from said internal coil by the skin of a subject, said external coil being coupled to transmit electric power to said internal coil through the skin of a subject; and a DC-to-AC converter coupled to said external coil and to a source of DC power, said DC-to-AC converter causing AC current to flow through said external coil, said DC-to-AC converter selectively converting DC power from said DC power source into either a first frequency during a first period of time or a second frequency during a second period of time, said first frequency being different than said second frequency.
