Abstract
An implantable cardiac defibrillator is provided having an energy source, a capacitor, and means coupled to the energy source for charging the capacitor. The capacitor comprises a planar layered structure of anode plates, cathode plates and means separating the anode plates and cathode plates. A polymeric envelope containing electrolyte encloses the layered structure. Electrical contact means extend from the anodes and cathodes to outside the envelope.
