A conductive ferrule disposed adjacent to the capacitor includes a conductive pad of an oxide resistant biostable material on a surface thereof conductively coupled to the second termination surface. A conductive terminal pin extends through the passageway in conductive relation with the first set of electrode plates, and through the ferrule in non-conductive relation. An insulator is fixed to the ferrule for conductively isolating the terminal pin from the ferrule. A hermetic seal is disposed between the insulator and the ferrule. A second conductive pad may be conductively attached to the terminal pin and to the first termination surface independently of the lead wire.

摘要： EMI feedthrough filter terminal assembly includes a feedthrough filter capacitor having first and second sets of electrode plates, and a first passageway having a first termination surface conductively coupling the first set of electrode plates. At least one lead wire extends through the first passageway and is conductively attached to a first oxide resistant conductive pad. The first pad is conductively coupled to the first termination surface independently of the lead wire. The terminal assembly may also include a conductive ferrule through which the lead wire passes in non-conductive relation, and an insulator fixed to the ferrule for conductively isolating the lead wire from the ferrule. The ferrule and insulator form a pre-fabricated hermetic terminal pin sub-assembly. The capacitor may include a second passageway having a second termination surface conductively coupling the second set of electrode plates, and a conductive ground lead extending therethrough.

摘要： An energy management system facilitates the transfer of high frequency energy coupled into an implanted abandoned lead at a selected RF frequency or frequency band, to an energy dissipating surface. This is accomplished by conductively coupling the implanted abandoned lead to the energy dissipating surface of an abandoned lead cap through an energy diversion circuit including one or more passive electronic network components whose impedance characteristics are at least partially tuned to the implanted abandoned lead's impedance characteristics.

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.

摘要： A feedthrough terminal assembly for active implantable medical devices includes a structural wire bond pad for a convenient attachment of wires from either the circuitry inside the implantable medical device or wires external to the device. Direct attachment of wire bond pads to terminal pins enables thermal or ultrasonic bonding of lead wires, while shielding the capacitor or other delicate components from the forces applied to the assembly during attachment of the wires.

摘要： A feedthrough terminal assembly for an active implantable medical device includes a conductive ferrule conductively coupled to a housing of the medical device, a feedthrough capacitor conductively coupled to the ferrule, an inductor closely associated with the capacitor in non-conductive relation, and a conductive terminal pin extending through the capacitor and the inductor. The terminal pin extends through the inductor in non-conductive relation and is conductively coupled to active electrode plates of the capacitor. In one preferred form, the terminal pin is wound about the inductor. Additionally, the inductor may be maintained in close association with the capacitor without forming a direct physical attachment therebetween.

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. In a preferred form, the TANK filter reduces or even eliminates the use of ferro-magnetic materials, and instead uses non-ferromagnetic materials so as to reduce or eliminate MRI image artifacts or the force or torque otherwise associated during an MRI image scan.
