    摘要: A feedthrough terminal pin assembly includes an outer ferrule hermetically sealed through a braze joint to an insulator seated within the ferrule is described. The insulator is also hermetically brazed to at least one terminal pin. The terminal pin is provided with a braze retention structure such as an annular groove that prevents braze material from filleting past the groove. Similarly, either the ferrule or the insulator is provided with a retention structure such as an annular groove that prevents braze material spill out from the insulator/ferrule interface. In that manner, the braze retention structures keep braze material from accumulating in unwanted areas where it could adversely affect hermeticity as well as proper attachment of an EMI filter to the feedthrough assembly.

    摘要: In an electromagnetic interference (EMI) filter terminal for an active implantable medical device (AIMD), an insulated and shielded RF telemetry pin is provided to prevent re-radiation of unwanted stray signals, including the telemetry signal itself, to adjacent sensitive circuits or lead wires. The invention provides for an EMI filter terminal assembly for an AIMD including a radio frequency (RF) telemetry pin antenna extending therethrough. The RF telemetry pin antenna includes a conductive shield extending over a portion of the RF telemetry pin antenna in non-conductive relation with the telemetry pin, and conductively connected to a ground associated with the AIMD. The assembly may also include an insulation tube between the RF telemetry pin antenna and the conductive shield covering a portion of the RF telemetry pin antenna.

    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.
