ABSTRACT:
An implantable tissue stimulator includes a polymer film capacitor adhered to an inside wall surface of the stimulator's case or housing in a way that minimizes the size and weight of the stimulator device. The energy storage capacitor for the tissue stimulator comprises a monolithic, multi-layer device and where the polymer is a suitable acrylate of a known formulation, over 1500 parallel plate capacitor electrodes can be built it with the height dimension of the resulting capacitor being less than about 3 mms. Instead of forming the capacitor on the inner surface of the stimulator's case in situ, such a capacitor can be formed on a mold member corresponding in shape to the inner surface of the stimulator's case and inserted into the stimulator's case following removal from the mold.
