Abstract
An implantable medical device, such as a pacemaker, cardioverter or defibrillator, having a detachable power source, so that either the power source or the electronic circuitry can be replaced. The device comprises an electronics package having a header for connection to leads coupled to the patient'"'"'s heart and a battery connector comprising a header-like coupler. The device further comprises a battery pack having a second header-like coupler. The couplers mate together mechanically and are joined electrically by a separate pin. The pin has a coupling on both ends thereof so that one end can extend into the coupler of the electronics package and another end can extend into the coupler of the battery package. Alternatively, such a connector or pin, having a male configuration, could be provided on either the electronics coupler or the battery coupler with a corresponding female configuration on the other coupler.
