Abstract
A method of forming a filtering capacitor feedthrough assembly for an implantable active medical device includes inserting a terminal pin into an aperture of a capacitor, the capacitor configured to be electrically grounded to an electrically conductive feedthrough ferrule or housing of the implantable active medical device, then disposing an electrically conductive continuous coil within the aperture between the terminal pin and the capacitor and then fixing the continuous coil to the terminal pin or the capacitor. The continuous coil includes an inner diameter defined by a plurality of coils, the terminal pin extending through the inner diameter of the continuous coil so that the plurality of coils circumferentially surround the terminal pin. The electrically conductive continuous coil mechanically secures and electrically couples the terminal pin to the capacitor.
