Electrode design for implantable device applications that require the elective replacement indicator (ERI)

摘要

A method for providing a physician with an elective replacement indicator (ERI) for an implantable medical device is described. The medical device is powered by an electrochemical having a lithium anode coupled to a sandwich cathode comprising the configuration: SVO/current collector/CFx, with the SVO facing the anode. The indicator is predicated on when the cell's discharge capacity is nearing end-of-life (EOL) based on the theoretical capacity and the discharge efficiency of the SVO and CFx active materials. This serves as an indicator when it is time to replace the medical device. IMAGE
