  • Degradable implantable battery
    Patent number: 9362571
    Abstract: A biodegradable battery is provided. The battery includes an anode comprising a material including an inner surface and an outer surface, wherein electrochemical oxidation of the anode material results in the formation of a reaction product that is substantially non-toxic and a cathode comprising a material including an inner surface and an outer surface, the inner surface of the cathode being in direct physical contact with the inner surface of the anode, wherein electrochemical reduction of the cathode material results in the formation of a reaction product that is substantially non-toxic, and wherein the cathode material presents a larger standard reduction potential than the anode material.
    Type: Grant
    Filed: January 23, 2015
    Date of Patent: June 7, 2016
    Assignee: Covidien LP
    Inventors: Gerald Hodgkinson, William O. Powers, Ahmad Robert Hadba
