Abstract: Terminal pins that include a refractory metal forming a full perimeter weld connected to a terminal block including a dissimilar metal incorporated into feedthrough filter capacitor assemblies are discussed. The feedthrough filter capacitor assemblies are particularly useful for incorporation into implantable medical devices such as cardiac pacemakers, cardioverter defibrillators, and the like, to decouple and shield internal electronic components of the medical device from undesirable electromagnetic interference (EMI) signals.

Abstract: A capacitor comprising a cylindrical casing sidewall extending to closed first and second end walls and an anode assembly housed therein including a first, second and third anodes is described. Each anode comprises an anode sidewall extending to first and second anode end walls and a conductive lead extending therefrom. The anodes are in a side-by-side relationship within the casing with their respective sidewalls parallel to each other. The cathode of the capacitor may include a first conductive substrate supporting a cathode active material. The conductive substrate is wrapped around the anodes, and the cathode active material is disposed on the substrate at locations such that the respective sidewalls of the anodes are opposed by cathode active material. A separator is positioned between the side-by-side anodes and the cathode. The open volume within the casing is filled with an electrolyte, and the casing is hermetically sealed.

Abstract: A capacitor having a cylindrical shape or configuration so that it is capable of being inserted directly into the vasculature of a patient is described. A typical diameter for the present capacitor is about 6 mm. A capacitor of this size would occupy about 9% of the total cross-sectional area of the inferior vena cava prior to the crossover to the heart, where the typical diameter of the vein is about 20 mm. The crossover section has a diameter of about 11 mm to about 12 mm.
