摘要： A process for manufacturing an EMI filter feedthrough terminal assembly is provided for mating a feedthrough filter capacitor with an hermetic terminal assembly including a ferrule and one or more lead wires which extend through the ferrule in non-conductive relation. The process includes the steps of placing the hermetic terminal assembly, having a capture flange, into a holding fixture, and forming a seat of non-conductive thermal-setting material onto the terminal assembly within the capture flange. A feedthrough filter capacitor is loaded into the capture flange on top of the seat, and then the seat is cured. A conductive thermal-setting material is dispensed between an outer diameter of the feedthrough filter capacitor and the capture flange. The assembly is then centrifuged to pack the conductive thermal-setting material. The conductive thermal-setting material is then cured between the outer diameter of the feedthrough filter capacitor and the capture flange. Preferably, the height of the capture flange is one-quarter to three-quarters of an axial thickness of the capacitor.

摘要： An EMI filter feedthrough terminal assembly includes at least one conductive terminal pin, a feedthrough filter capacitor which has a passageway through which the terminal pin extends, and a conductive substrate through which the terminal pin passes in non-conductive relation. The conductive substrate includes a capture flange having a height that is less than an axial thickness of the capacitor and which is configured to at least partially surround an outer periphery of the capacitor. The height of the capture flange is preferably one-quarter to three-quarters of the axial thickness of the capacitor. A first set of capacitor electrodeplates is conductively coupled to the terminal pin, and a second set of electrode plates is conductively coupled to the capture flange by means of a thermal-setting conductive material disposed between the outer periphery of the capacitor and the capture flange. A related process is provided for manufacturing an EMI filter feedthrough terminal assembly that advantageously utilizes the capture flange.

摘要： An integrated hermetically sealed feedthrough capacitor filter assembly is provided for the shielding and decoupling of a conductive terminal pin or lead of the type used, for example, in an implantable medical device such as a cardiac pacemaker or cardioverter defibrillator against passage of external interference signals, such as caused by digital cellular phones. The simplified feedthrough assembly described herein eliminates the traditional terminal pin subassembly. In this novel approach, the ceramic feedthrough capacitor itself forms a hermetic seal with a conductive pacemaker housing to which it is mounted by welding or brazing. The feedthrough capacitor is configured such that its internal electrodes are not exposed to body fluids, with capacitor electrode plate sets coupled respectively to a conductive ferrule, pin or housing (which may be grounded) and to the non-grounded, or active, terminal pin(s) by conductive adhesive, soldering, brazing, welding or the like. In one preferred form, multiple feedthrough filter capacitors are provided in a substantially coplanar array within a common base structure, with each capacitor in association with a respective terminal pin.

摘要： A TANK filter is provided for a lead wire of an active medical device (AMD). The TANK 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 TANK 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 TANK filter to attenuate current flow through the lead wire along a range of selected frequencies. In a preferred form, the TANK filter is integrated into a TIP and/or RING electrode for an active implantable medical device.
