ABSTRACT:
A body implantable medical device (IMD) includes a first shell and a second shell whose outer surfaces are biocompatible. The IMD further includes a battery enclosure defined by all or a portion of the first shell of the IMD housing and a cover. The cover of the battery enclosure is disposed between the inner surfaces of the first and second shells, has a greater rigidity than the first shell, and includes an improved feedthrough assembly for an electrochemical cell, such as a flat liquid electrolyte battery, provided in the battery enclosure. Electronic circuitry, supported on a flexible wiring substrate, is provided between the inner surface of the second shell and the cover of the battery enclosure. A hermetic seal is provided between the cover of the battery enclosure and all or a portion of the first shell.
