Patent number: 9427596Abstract: A hermetically sealed filtered feedthrough assembly for an AIMD includes an electrically conductive ferrule with an electrically conductive extension at least partially extending into the ferrule opening. An electrically non-conductive insulator hermetically seals the ferrule opening. An electrically conductive pathway is hermetically sealed and disposed through the insulator between a body fluid and device side. A filter capacitor is located on the device side. A first low impedance electrical coupling is between a first metallization of the filter capacitor and the pathway. A ground conductor is disposed through the filter capacitor in non-conductive relation with the at least one active and ground electrode plates, where the ground conductor is electrically coupled to the extension of the ferrule. An oxide-resistant metal addition is disposed on the device side and electrically couples the ground conductor to the second metallization of the filter capacitor.Type: GrantFiled: August 14, 2015Date of Patent: August 30, 2016Assignee: Greatbatch Ltd.Inventors: Jason Woods, Richard L. Brendel, Robert A. Stevenson, Christopher Michael Williams, Robert Naugler, Christine A. Frysz

Patent number: 9108066Abstract: A hermetically sealed filtered feedthrough assembly for an AIMD includes an insulator hermetically sealed to a conductive ferrule or housing. A conductor is hermetically sealed and disposed through the insulator in non-conductive relation to the conductive ferrule or housing between a body fluid side and a device side. A feedthrough capacitor is disposed on the device side. A first low impedance electrical connection is between a first end metallization of the capacitor and the conductor. A second low impedance electrical connection is between a second end metallization of the capacitor and the ferrule or housing. The second low impedance electrical connection includes an oxide-resistant metal addition attached directly to the ferrule or housing and an electrical connection coupling the second end metallization electrically and physically directly to the oxide-resistant metal addition.Type: GrantFiled: March 10, 2014Date of Patent: August 18, 2015Assignee: Greatbatch Ltd.Inventors: Jason Woods, Richard L.

Patent number: 7715923Abstract: High reliability electrical connections between a helical strand and flat electrodes, such us strip electrodes found in implantable neurostimulator system, are described. The connection consists of a crimp joint in which an inside diameter mandrel is used to provided the coil with sufficient radial rigidity to ensure structural integrity of the crimp. The mandrel is made of a relatively soft biocompatible material that deforms rather than damages the fine wires of the helical strand during crimping. The crimping is accomplished by radial deformation of an annular or semi-annular crimping member that receives the helical strand/mandrel assembly.Type: GrantFiled: March 6, 2007Date of Patent: May 11, 2010Assignee: Greatbatch Ltd.Inventors: Robert C. O'Brien, Robert Naugler, Warren Dabney, Christine A Frysz, Andrew Fisk

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
