METHOD FOR ELECTRODE DESIGN FOR IMPLANTABLE DEVICE APPLICATIONS THAT REQUIRE THE ELECTIVE REPLACEMENT INDICATOR (ERI)

摘要

A method for providing a physician with an electivereplacement indicator (ERI) for an implantable medical deviceis described. The medical device is powered by anelectrochemical having a lithium anode coupled to a sandwichcathode comprising the configuration: SVO/currentcollector/CF x, with the SVO facing the anode. The indicatoris predicated on when the cell's discharge capacity isnearing end-of-life (EOL) based on the theoretical capacityand the discharge efficiency of the SVO and CF x activematerials. This serves as an indicator when it is time toreplace the medical device.
