Publication number: 20100063555Abstract: A one-piece electrical contact ring for use in a lead receptacle of an implantable medical device includes (i) a tubular body defining a cavity extending through the body and (ii) a plurality of resiliently deflectable elements extending from the tubular body into the cavity. The deflectable elements have a lead contacting portion configured to contact the lead when received by the cavity. The lead contacting portions of the deflectable elements in a relaxed state are located in a plane that intersects the tubular body and are configured to deflect along the plane towards the tubular body as the lead is inserted in the contact ring. The contact ring may further include a plurality of stops, each configured to (i) engage a stop portion of the elements when the elements are sufficiently outwardly deflected and (ii) inhibit further outward deflection of the elements when the stops engage the stop portions.Type: ApplicationFiled: September 8, 2009Publication date: March 11, 2010Applicant: MEDTRONIC, INC.Inventors: Darren A. Janzig, Chris J. Paidosh, Paulette C. Olson, Gerald G. Lindner

Publication number: 20070185539Abstract: A modular implantable medical device permits implantable medical devices to have a smaller profile in order to better fit into locations within the human body. A modular implantable medical device separates various functional components of the implantable medical device into a set of interconnected modules. This distributed architecture of a modular implantable medical device may permit the device footprint to be distributed over a larger area while making the profile smaller, and may permit the overall shape of the implantable medical device to better match the body location into which it is to be implanted. An overmold integrates the modules of a modular implantable medical device into a single structure. In some embodiments the overmold is flexible and provides a biocompatible interface from the component modules and the patient, while restraining potentially harmful intermodule motion.Type: ApplicationFiled: April 16, 2007Publication date: August 9, 2007Applicant: Medtronic, Inc.Inventors: Ruchika Singhal, Darren Janzig, Carl Wahlstrand, Robert Skime, Paulette Olson

Publication number: 20040176815Abstract: Components of an implantable medical device are arranged to facilitate a low-profile housing. A circuit board within the housing carries integrated circuits and discrete components. In some embodiments, the integrated circuits and discrete components are located on first and second opposing surfaces of the circuit board, respectively. In some embodiments, the implantable medical device is implanted on a cranium of a patient and the housing is concave such that it substantially conforms to the cranium. In such embodiments, the integrated circuits and/or discrete components can be arranged on the circuit board according to height to better conform to the concavity of the housing. In some embodiments, the implantable medical device includes a telemetry coil that is positioned within the housing such that it occupies space that cannot be practically occupied by the circuit board.Type: ApplicationFiled: December 9, 2003Publication date: September 9, 2004Inventors: Darren A.
