Patent number: 8442646Abstract: An inner surface of a coupling component sidewall forms first and second portions of a cavity of the coupling component. A conductive coupling between an electrode and a conductor of a medical electrical lead may be formed by inserting a segment of the conductor into the first portion of the cavity, crimping the sidewall of the coupling component around the inserted segment, inserting a segment of the electrode into the second portion of the cavity, and welding an edge of the sidewall to the inserted electrode segment. The edge of the sidewall may define a slot, extending between first and second portions of the cavity, or a hole extending through the sidewall. The electrode may be part of an electrode assembly, mounted around an inner insulation layer of the lead, and the conductor may be part of a conductor assembly extending between inner and outer insulation layers of the lead.Type: GrantFiled: May 17, 2010Date of Patent: May 14, 2013Assignee: Medtronic, Inc.Inventors: Kevin R. Seifert, Gregory A. Boser, Jonathan A. Hughes, Michael R. Dollimer

Patent number: 7277762Abstract: 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: GrantFiled: October 25, 2002Date of Patent: October 2, 2007Inventors: Elisabeth L. Belden, Gregory A. Boser, Michael R. Dollimer, Mary M. Morris

Patent number: 6016436Abstract: An implantable electrical lead of the type which has an insulative rigid electrode head carrying an advanceable helical electrode. The electrode head is mounted toan elongated insulative lead body which is less rigid than the electrode head and which carries an extensible conductor coupled to the helical electrode and an inextensible conductor coupled to the proximal end of the lead body. A second electrode is mounted to said lead body adjacent the electrode head and is coupled to the inextensible conductor by a conductive sleeve which is mechanically coupled to electrode head so that proximally directed traction forces applied to the lead body are applied by the inextensible conductor directly to the electrode head.Type: GrantFiled: September 26, 1997Date of Patent: January 18, 2000Assignee: Medtronic, Inc.Inventors: Thomas C. Bischoff, Michael R. Dollimer, William J. Eastman

Patent number: 5807399Abstract: A method of removing chronically implanted pacing leads and leads specifically adapted to be removed using the method. The leads are constructed so that upon tension applied to the electrode, it is withdrawn to a first location, so that upon further application of tension, the sheath located distal to the withdrawn electrode may collapse, enhancing its removability. In some embodiments of leads particularly adapted for use in conjunction with the method, the leads are provided with a mechanism for allowing breakage of the lead adjacent the points to which the electrode has been withdrawn, upon application of further tension to the electrode.Type: GrantFiled: October 23, 1996Date of Patent: September 15, 1998Assignee: Medtronic, Inc.Inventors: Timothy G. Laske, Pedro A. Meregotte, Michael R. Dollimer

Patent number: 5584873Abstract: A medical electrical lead having a multiple conductors located within an elongated lead body which is provided with multiple conductor lumens each containing a conductor and with at least one compression lumen which does not contain a conductor. The conductor lumens are spaced from one another by a first, minimum spacing and the compression lumen or lumens are located intermediate the conductor lumens and are spaced from the conductor lumens by a second, minimal spacing of less then said first minimum spacing. The centers of the compression lumens are located along lines which pass through the both the center of a conductor lumen and the center of the lead body. The arrangement of the conductor and compression lumens enhances the lead's ability to survive crushing forces such as applied by the first rib and clavicle.Type: GrantFiled: May 8, 1995Date of Patent: December 17, 1996Assignee: Medtronic, Inc.Inventors: Bret R. Shoberg, Svenn E. Borgersen, Michael R. Dollimer
