Abstract
An implantable cardioverter-defibrillator has a housing containing cardioverter-defibrillator circuitry and a capacitor assembly. The capacitor assembly includes at least two flat capacitors each having opposed major surfaces. Each capacitor has an anode contact at one major surface, and a cathode contact at the opposite major surface. The anode contact of one of the capacitors contacts the cathode contact of the other. Each capacitor contact may be a thin metal plate covering the entire surface of the capacitor, with each plate connected to corresponding interleaved cathode or anode flat sheets between the plates. A non-conductive perimeter may enclose the sheets and connect the plates to each other.
Claims13
An electrolytic capacitor comprising:
- a flat anode contact plate forming a first capacitor housing portion;
- a flat cathode contact plate parallel to and spaced apart from the anode contact plate and forming a second capacitor housing portion;
- and
- a planar charge storage element closely received between the contact plates, the planar charge storage element comprising a stack of interleaved flat anode sheets and flat cathode sheets, and the flat anode sheets and the flat cathode sheets disposed parallel to the flat anode contact plate and the flat cathode contact plate;
- wherein the cathode sheets are commonly electrically connected to the cathode contact plate, and the anode sheets are commonly electrically connected to the anode contact plate.
