Assignee:

Greatbatch-Sierra, Inc. - Carson City NV

International Classification:

A61N 1/375
A61N 1/16

US Classification:

607 37, 607 36

Abstract:

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.

US Classification:

361302, 3613062, 361311, 361313, 333182, 333185, 607 5

Abstract:

A feedthrough terminal assembly for an active implantable medical device utilizes an insert to establish a reliable electrical connection between capacitor electrode plates, via inner surface metallization of a capacitor aperture, and an associated terminal pin , which passes at least partially therethrough. The inserts are preferably resiliently flexible, such as a spring, to establish this connection. The insert also serves to establish a mechanical connection between the capacitor and the terminal pin.

International Classification:

H01J 5/00

US Classification:

174 506, 174 5056, 174 5061, 361302, 29 2542

Abstract:

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.

Assignee:

Greatbatch-Sierra, Inc. - Carson City NV

International Classification:

A61N 1/375

US Classification:

607 36, 607 63

Abstract:

An active implantable medical device (AIMD) having a magnetic shield on its housing for shielding the interior of the device from magnetic fields originating outside the housing. The magnetic shield is created using a magnetic absorbing coating on the inner surface of the housing. The AIMD includes an area of the housing left without the magnetic shield, a magnetic window, adjacent to a magnetically actuated device located inside of the housing. The magnetic window permits activation of the magnetically actuated device.

Abstract:

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.
