Abstract
Battery-powered implantable medical devices require a suitable method for indicating end-of-service of the power source so that there is ample time for elective replacement of the device and/or power source. The present invention utilizes mixed cathode materials preferably comprising a major portion of a fluorinated carbon and a minor portion of a metal-containing material. This mixed cathode formulation is characterized by two, discretely different operating voltages, the second of which may be used as an end-of-life indicator.
