Abstract: A band stop filter is provided for a lead wire of an active medical device (AMD). The band stop filter includes a capacitor in parallel with an inductor. The parallel capacitor and inductor are placed in series with the lead wire of the AMD, wherein values of capacitance and inductance are selected such that the band stop filter is resonant at a selected frequency. The Q of the inductor may be relatively maximized and the Q of the capacitor may be relatively minimized to reduce the overall Q of the band stop filter to attenuate current flow through the lead wire along a range of selected frequencies. In a preferred form, the band stop filter is integrated into a TIP and/or RING electrode for an active implantable medical device.

Abstract: A feedthrough terminal assembly for an active implantable medical device (AIMD) includes a conductive terminal pin or lead wire which extends through a conductive ground plane of the AIMD in non-conductive relation. A feedthrough capacitor associated with the terminal pin or lead wire has first and second sets of electrode plates coupled, respectively, to the conductive pin or lead wire and to the ground plane. A breathable electromechanical connection material conductively couples the capacitor's electrode plates to respective components of the AIMD, which allows helium gas to pass freely therethrough during a standard pressurized or vacuum pull helium leak detection test. A breathable washer may be disposed between an alumina insulator and a surface of the capacitor. An additional further breathable coating or conformal coating may be placed over a surface of the feedthrough capacitor disposed toward the interior of the AIMD.
