Summary form only given. Safe electric power provision to medical implants, such as pacemakers and artificial hearts, is much needed, because those medical devices are becoming more sophisticated. Up to the present, several noninvasive methods of transmitting power to a rechargeable battery for implanted medical devices have been reported. In this paper, we propose a novel electric power provision system to a medical implant at a deep position in the body. A permanent magnet rotor is set up outside the body. Another permanent magnet rotor, in which a generator has been installed, is implanted. The magnets of the rotors have magnetic coupling each other. When the rotor outside the body rotates, the other rotor in the body synchronously rotates and the electric power is generated from the mechanical power.
