Abstract
Abstract A biogalvanic power supply device for an apparatus implanted in a body comprising a cathode placed in the venous circulating stream and an anode placed in subcutaneous tissue of the body. The cathode comprises a platinum material coactable with biological substances in the body when it is placed in the venous circulating system. The anode comprises a material, such as magnesium, which is consumed when implanted in subcutaneous tissue of the body. The anode is placed in the subcutaneous tissue at a distance from the cathode which is effective to preclude inhibiting the action of the cathode as the anode is progressively consumed. An electrical connection is provided between the anode and the cathode for flowing therethrough a current flow.
