    Abstract: A hermetic terminal assembly for an AIMD includes a shielded three-terminal flat-through EMI energy dissipating filter and a hermetically sealed feedthrough configured to be attachable to the ferrule or AIMD housing. The flat-through filter includes a first shield plate, an active electrode plate, and a second shield plate where the shield plates are electrically coupled to a metallization which in turn is coupled either to the ferrule or AIMD housing. The feedthrough includes an alumina substrate comprised of at least 96% alumina and a via hole with a substantially closed pore and substantially pure platinum fill. The platinum fill forms a tortuous and mutually conformal knitline or interface between the alumina substrate and the platinum fill, wherein the platinum fill is electrically coupled to at least one active electrode plate in non-conductive relationship to the at least one first and second shield plates.

    Abstract: A feedthrough filter capacitor assembly comprising a terminal pin connector is described. The terminal pin connector is designed to facilitate an electrical connection between the terminal pin comprising a multitude of compositions to a circuit board of an implantable medical device. The terminal pin connector comprises a clip portion positioned within a connector housing. The connector clip mechanically attaches to the terminal pin of the feedthrough with at least one prong and an exterior surface of the connector housing electrically contacts the circuit board, creating an electrical connection therebetween. The connector housing comprises a material that is conducive to a weld or solder attachment process to the circuit board. The feedthrough filter capacitor assembly is 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: An AIMD includes a conductive housing, an electrically conductive ferrule with an insulator hermetically sealing the ferrule opening. A conductive pathway is hermetically sealed and disposed through the insulator. A filter capacitor is disposed within the housing and has a dielectric body supporting at least two active and two ground electrode plates interleaved, wherein the at least two active electrode plates are electrically connected to the conductive pathway on the device side, and the at least two ground electrode plates are electrically coupled to either the ferrule and/or the conductive housing. The dielectric body has a dielectric constant less than 1000 and a capacitance of between 10 and 20,000 picofarads. The filter capacitor is configured for EMI filtering of MRI high RF pulsed power by a low ESR, wherein the ESR of the filter capacitor at an MRI RF pulsed frequency or range of frequencies is less than 2.0 ohms.
