ABSTRACT:
An energy dissipation resistor for dissipating electrical energy stored in implantable defibrillation capacitor(s). The resistor comprises a layer of resistive foil sandwiched between two layers of electrically insulative material so as to define a circuitous resistive path. At least two electrically conductive contacts are disposed through one of the insulative layers such that each of the contacts provides an electrically conductive path from the exterior of the energy dissipation resistor to the resistive foil layer enclosed therein. Conductive leads are electrically connected to the conductive contacts and provide a means by which the energy dissipation resistor can be connected to defibrillation circuitry. The energy dissipation resistor can also be formed integrally with a flexible circuit board, a rigid circuit board, a circuitry liner, or a hybrid substrate.
