Abstract

See full text

A battery-operated implantable medical device comprises a battery, a measuring device for determining the state of charge of the battery through measurement of the no-load voltage, and an electric load. The no-load voltage of the battery has an increased drop in a range in which a remaining residual energy suffices to keep the operation of the device going for a minimum period of time required to carry out a therapeutic process.
