Patent number: 9629998Abstract: Implantable medical leads and implantable lead extensions include a shield. The implantable medical lead is coupled to the implantable lead extension. Stimulation electrodes of the implantable medical lead contact stimulation connectors within a housing of the implantable extension to establish a conductive pathway for stimulation signals from filars of the implantable extension to filars of the implantable medical lead. Continuity is established between the shield of the implantable medical lead and the implantable extension by providing a radio frequency conductive pathway within the housing. The radio frequency conductive pathway extends from a shield of the implantable extension to a shield connector that contacts a shield electrode of the implantable medical lead. The radio frequency conductive pathway may have various forms such as a jumper wire or an extension of the shield within the implantable extension.Type: GrantFiled: April 6, 2015Date of Patent: April 25, 2017Assignee: MEDTRONICS, INC.Inventors: James M. Olsen, Bruce R. Mehdizadeh, Michael J. Kern

Publication number: 20170007827Abstract: A shield located within an implantable medical lead may be terminated in various ways at a metal connector. The shield may be terminated by various joints including butt, scarf, lap, or other joints between insulation layers surrounding the lead and an insulation extension. The shield may terminate with a physical and electrical connection to a single metal connector. The shield may terminate with a physical and electrical connection by passing between an overlapping pair of inner and outer metal connectors. The metal connectors may include features such as teeth or threads that penetrate the insulation layers of the lead. The shield may terminate with a physical and electrical connection by exiting a jacket of a lead adjacent to a metal connector and lapping onto the metal connector.Type: ApplicationFiled: August 31, 2016Publication date: January 12, 2017Inventors: Bruce R. Mehdizadeh, Brian T. Stolz, Michael Robert Klardie, James M. Olsen, Michael J. Kern, Richard T. Stone, Chad Q. Cai, Spencer M. Bondhus, Mark J. Conroy, Timothy R. Abraham

Patent number: 8721661Abstract: An extensible implantable medical device includes a body defining a lumen extending through the body. The lumen is configured to receive at least a portion of an implantable medical lead. The body includes a non-rectilinearly shaped portion.

Publication number: 20120130461Abstract: Radiopaque markers represent that a lead is suitable for a particular medical procedure such as a magnetic resonance image scan and are added to the lead or related device. The markers may be added after implantation of the lead in various ways including suturing, gluing, crimping, or clamping a radiopaque tag to the lead or to the device. The markers may be added by placing a radiopaque coil about the lead, and the radiopaque coil may radially contract against the lead to obtain a fixed position. The markers may be added by placing a polymer structure onto the lead where the polymer structure includes a radiopaque marker within it. The polymer structure may include a cylindrical aperture that contracts against the lead to fix the position of the structure. The polymer structure may form a lead anchor that includes suture wings that can be sutured to the lead.Type: ApplicationFiled: April 28, 2010Publication date: May 24, 2012Applicant: MEDTRONIC, INC.Inventors: James M.
