Apparatus for transmitting energy to a device implanted in a living body
First Claim
1. Apparatus for supplying energy from a source outside a living body to a device having an energy supply terminal implanted in the body comprising:
- means having an input adjacent the inside surface of the skin of the living body and including a bundle of optical fibers for transmitting light energy from said input to an output,said input also including a condensing lens for transmitting said light energy to said bundle of optical fibers,a protective membrane covering said bundle of optical fibers and said condensing lens;
an annular projection formed in said protective membrane and surrounding said condensing lens for facilitating the attachment of the apparatus to the inside surface of the skin by sewing;
means for receiving said light energy from said output, for converting said light energy to electrical energy, and for applying said electrical energy directly to the energy supply terminal of said implanted device; and
energy source means for applying light energy to the outside surface of the skin of the living body opposite said input of the energy-transmitting means, said applied light energy penetrating the skin without rupturing the skin and entering said input.

Abstract
Apparatus for applying energy to the outside of the skin for penetrating the skin, a transducer for converting the energy penetrating the skin to a form of energy utilizable by a device implanted in the body, and a member for transmitting the skin penetrating energy to the transducer. Preferably the applied energy is infrared light or heat with the transmitting member being optical fibers or a heat pipe, respectively, and the implanted device is a pacemaker for the heart, the battery of the pacemaker being rechargeable by the converted energy and the pulse generator of the pacemaker being controllable by the converted energy.
