Patent ID: 8761877

Claim:
A biosorbable battery assembly comprising: an anode comprising an anode material, wherein the anode material is electrochemically oxidized during discharge to release reaction products that are substantially non-toxic and wherein the anode material is configured to dissolve into extracellular fluid of a patient after electrochemical oxidation of the anode material; a cathode comprising a cathode material, wherein the cathode material is electrochemically reduced during discharge to form reaction products that are substantially non-toxic and wherein the cathode material is configured to dissolve into extracellular fluid of a patient after electrochemical reduction of the cathode material, the cathode material having a larger standard reduction potential than the anode material; and a biosorbable separation element comprising non-toxic electrolytes and a polymeric matrix, the biosorbable separation element disposed between the anode and the cathode and configured to provide electrical insulation between the anode and the cathode.
