Publication number: 20220409909Abstract: A feedthrough assembly for an implantable medical device includes a housing, a solid insert, one or more conductive elements, a metal filler, and a non-corrosive sealant. The housing defines a central cavity through a height of the housing. The solid insert is disposed within the central cavity of the housing. The one or more conductive elements extend through one or more apertures defined within the solid insert and extend through the central cavity of the housing. The metal filler is disposed within a joint defined by an outer surface of the solid insert and an inner surface of the housing that defines the central cavity. The non-corrosive sealant coats a top surface of the metal filler to inhibit corrosion of the metal filler.Type: ApplicationFiled: June 23, 2021Publication date: December 29, 2022Inventors: Haytham Hussein, John Szymanski, Kavous Sahabi, Ofer Rosenzweig, Stella Nichols

Patent number: 8160705Abstract: 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.Type: GrantFiled: January 31, 2006Date of Patent: April 17, 2012Assignee: Greatbatch LtdInventors: Robert A.

Patent number: 7797048Abstract: A feedthrough terminal assembly for an active implantable medical device (AIMD) includes a conductive terminal pin or lead wire which extends through a conductive ground plane of the AIMD in non-conductive relation. A feedthrough capacitor associated with the terminal pin or lead wire has first and second sets of electrode plates coupled, respectively, to the conductive pin or lead wire and to the ground plane. A breathable electromechanical connection material conductively couples the capacitor's electrode plates to respective components of the AIMD, which allows helium gas to pass freely therethrough during a standard pressurized or vacuum pull helium leak detection test. A breathable washer may be disposed between an alumina insulator and a surface of the capacitor. An additional further breathable coating or conformal coating may be placed over a surface of the feedthrough capacitor disposed toward the interior of the AIMD.Type: GrantFiled: March 22, 2007Date of Patent: September 14, 2010Assignee: Greatbatch Ltd.Inventors: Robert A.

Patent number: 7145076Abstract: 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.Type: GrantFiled: February 7, 2006Date of Patent: December 5, 2006Assignee: Greatbatch, Inc.Inventors: Scott Knappen, Robert Naugler, Haytham Hussein, Thomas Shipman, Richard Brendel, Christine Frysz
