Publication number: 20110160573Abstract: A cardiac transvenous defibrillation lead has a continuous coil conductor within a layer of insulation. A portion of the coil conductor is exposed as a defibrillation electrode. In order to enhance fluoroscopic visualization of the exposed electrode during implant, the end of the exposed electrode is marked with a radiopaque element. The element may be in the form of an adhesive filled with radiopaque material that is used to backfill under the layer of insulation. Alternatively, a tube made of radiopaque material may be installed between the layer of insulation and the coil conductor.Type: ApplicationFiled: March 8, 2011Publication date: June 30, 2011Inventors: Elisabeth L. Belden, Mary M. Morris

Patent number: 7292894Abstract: A conductor assembly and methods for mechanically and electrically coupling a small diameter conductor to a lead component having a relatively larger sized conductor bore is provided. The assembly includes a sizing member sized to fit securely around a relatively small diameter conductor and to further fit within a conductor bore so that temporary compression (e.g., crimping, crushing, or staking) of a discrete portion of the conductor bore mechanically couples, and establishes electrical communication between, the conductor and the lead component. Alternately, a conductive sleeve member having a relatively large diameter conductor bore is adapted to receive a sizing unit to downsize one side of the sleeve member in a manner similar to the foregoing. In this case, a relatively smaller diameter one of a pair of different diameter elongated conductors is firmly mechanically coupled and in electrical communication with a relatively larger diameter conductor.Type: GrantFiled: September 27, 2002Date of Patent: November 6, 2007Assignee: Medtronic, Inc.Inventor: Elisabeth L.

Patent number: 7184839Abstract: A lead for delivering electrical signals to and/or receive electrical signals from a human heart that includes a solid inner conductor, and a fixation device having a titanium nitride coated surface and electrically coupled to the inner conductor. A steroid is applied to the titanium nitride surface of the fixation device, and at least one layer of insulation is positioned around the inner conductor. A conductive coil is positioned around and is insulated from the inner conductor, an electrode ring electrically coupled to the conductive coil is positioned around and is electrically isolated from the inner conductor, and an insulating spacer is positioned between and electrically isolates the ring electrode and the fixation device.Type: GrantFiled: December 16, 2002Date of Patent: February 27, 2007Assignee: Medtronic, Inc.Inventors: Willim J.

Patent number: 6968235Abstract: The present invention provides a practical, multi-polar, in-line connector system for use in connecting implantable medical devices (IMD) and associated non-standard, low profile medical electrical leads. In addition, the present invention provides a system that uses tool less, frictional, sealed, compressive electrical connections for most or all of the electrical interconnections between an IMD and a low profile lead. A protective sleeve seals the lead connector to the non-standard port to prevent intrusion of body fluids therein. In addition, optional microchip-based circuitry coupled to the sleeve enables wireless communication and remote programming for diverse IMDs. Memory associated with the circuitry can store, update and reprogram a wide variety of information relevant to the IMD, the patient, and the attending physician, among others. For example, the microchip may be used to identify the lead type and characteristics, as well as other useful data.Type: GrantFiled: April 30, 2002Date of Patent: November 22, 2005Assignee: Medtronic, Inc.Inventors: Elisabeth L.

Patent number: 6901289Abstract: A medical electrical lead is disclosed that is adapted for placement in the coronary sinus, or a branch vein thereof. The lead includes a first and second pace/sense electrode. A selection mechanism is provided to select either the first or the second electrode for use as a cathode, with the other electrode being selected as the anode. According to another aspect of the invention, a high-voltage coil electrode may be provided between the first and second electrodes. The coil electrode may be electrically coupled to the anode to increase the shadow area of the coil electrode.Type: GrantFiled: December 28, 2001Date of Patent: May 31, 2005Assignee: Medtronic, Inc.Inventors: Roger Dahl, Thomas M. Soukup, Joe Perttu, Arnold Thornton, Elisabeth L. Belden, John L. Sommer

Patent number: 5409455Abstract: An intravascular device to assist in the visualization of intravascular lumens and the navigation of guide members, the device including two elongate coaxial tubes which define a central lumen and an annular lumen. A manifold is coupled to the proximal end of the two tubes and includes a first port connected to the central lumen and a second port in fluid communication with the annular lumen. The central lumen and the annular lumen are fluidly independent at the proximal end and are open to the vasculature at the distal end. The coaxial tubes engage each other at the distal end to limit longitudinal movement therebetween.Type: GrantFiled: July 9, 1993Date of Patent: April 25, 1995Assignee: Scimed Life Systems, Inc.Inventor: Elisabeth L.
