Publication number: 20120215296Abstract: This application discusses, among other things, a header assembly for coupling a medical electrical lead to a medical stimulating device including a header having a capture mechanism within a bore of a lead retention device. In an example, when the lead retention device is retracted from the bore, the capture mechanism prevents the device from falling out. In another example, the header assembly has a vent disposed within the bore of the lead retention device that permits unrestricted flow of air when the lead retention device is retracted from an engagement surface.Type: ApplicationFiled: April 27, 2012Publication date: August 23, 2012Inventors: Andrew J. Ries, Eric J. Wengreen, Michael R. Klardie, Jennifer J. Zhao, Richard A. Bruchmann, Kathleen P. Macke, John E. Lovins, Randy S. Roles

Patent number: 7916448Abstract: A method of forming a filtering capacitor feedthrough assembly for an implantable active medical device includes inserting a terminal pin into an aperture of a capacitor, the capacitor configured to be electrically grounded to an electrically conductive feedthrough ferrule or housing of the implantable active medical device, then disposing an electrically conductive continuous coil within the aperture between the terminal pin and the capacitor and then fixing the continuous coil to the terminal pin or the capacitor. The continuous coil includes an inner diameter defined by a plurality of coils, the terminal pin extending through the inner diameter of the continuous coil so that the plurality of coils circumferentially surround the terminal pin. The electrically conductive continuous coil mechanically secures and electrically couples the terminal pin to the capacitor.Type: GrantFiled: April 13, 2010Date of Patent: March 29, 2011Assignee: Medtronic, Inc.Inventors: Jennifer J. Zhao, Micah A. Litow, Rajesh Iyer, Dawit Y. Belete, Simon E. Goldman, Shawn D. Knowles

Patent number: 7231253Abstract: An implantable medical device (IMD) includes a connector header for making electrical and mechanical connections with a proximal connector assembly of an electrical medical lead and includes a retainer for retaining a penetrable grommet within a header grommet aperture. A connector block disposed within a header body of the connector header has a threaded bore aligned with a header grommet aperture and a connector block bore aligned with a header connector bore. The penetrable grommet is disposed within the header grommet aperture, and a setscrew is threaded into the threaded bore having a setscrew socket disposed to be engaged by a tool inserted through the penetrable grommet within the header grommet aperture to enable rotation of the setscrew within the threaded bore to tighten the setscrew against or to loosen the setscrew from a lead connector element received in the header connector bore.Type: GrantFiled: December 11, 2003Date of Patent: June 12, 2007Assignee: Medtronic, Inc.Inventors: Kevin K. Tidemand, Daniel C. Haeg, Craig L. Wiklund, James F. Kelley, Jennifer J. Zhao, Andrew J. Ries, David C. Rice, Hui J. Jin, James J. Christenson, Loc Van Vo
