ABSTRACT:
An implantable electromedical device having a detachable, replaceable power supply. In one embodiment, the circuitry for an electromedical device is contained in a first hermetic enclosure, while a power supply for the device is contained in a second hermetic enclosure. The two enclosures are coupled together via a multiple conductor lead or the like, using any of the known assemblies commonly used for connection of pacing/sensing leads to an implantable device. A control signal generated by the device is applied to a control terminal on the battery enclosure. When the control signal is asserted, the battery is electrically coupled to two battery terminals on the battery enclosure, which terminals are coupled to power input terminals on the device itself. When the control signal is deserted, the battery is decouple from the battery terminals, so that there is no leakage current associated with the conduction of battery voltages on the connector between the two hermetic capsules. The disclosed arrangement may be advantageously utilized to allow for replacement of depleted batteries without explanation of the medical device itself, and to allow for different batteries to be used with the same device in different patients.
