Abstract
The present invention provides an implantable medical device having at least two electrodes coupled to the device housing. The electrodes may be configured for sensing physiological signals such as cardiac signals and alternatively for providing an electrical stimulation therapy such as a pacing or defibrillation therapy. In accordance with aspects of the disclosure, the device housing provides a hermetic enclosure that includes a battery case hermetically coupled to a circuit assembly case. At least one of the at least two electrodes is coupled to an exterior surface of the battery case. The battery case is electrically insulated from the cathode and anode of the battery.
