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 is adapted to pump blood from the blood inlet conduit to the blood outlet conduit. The apparatus includes an internal coupler adapted to be implanted beneath the skin of a subject and an external coupler operatively coupled to the internal coupler so that the external coupler induces an alternating electric current in the internal coupler. A rectification circuit is coupled to receive the alternating electric current induced in the internal coupler and generates DC electric power for the motor. The rectification circuit operates synchronously with, or at the same frequency as, the alternating current induced in the internal coupler and produces DC electric power from the alternating electric current. A drive circuit is operatively coupled to the rectification circuit and causes the rectification circuit to operate synchronously with, or at the same frequency as, the electric current induced in the internal coupler.
