Publication number: 20210267634Abstract: Subcutaneous implantation tools and methods of implanting a subcutaneous device using the same. The tool may include a tool body having a longitudinally extending recess having a distal opening and having a tunneler at a distal end of the tool body extending from the distal opening of the recess. The tool may include a plunger slidably fitting within at least a portion of the tool body recess. The recess may be configured to receive an implantable device and the tunneler preferably extends distally from the recess at a position laterally displaced from the device when the device is so located in the recess. Movement of the plunger distally within the recess advances the device distally out of the recess and alongside of and exterior to the tunneler.Type: ApplicationFiled: May 18, 2021Publication date: September 2, 2021Inventors: Matthew T.

Publication number: 20200139111Abstract: 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 polymer structure. The polymer structure may form a lead anchor that includes suture wings that can be sutured to the lead.Type: ApplicationFiled: December 19, 2019Publication date: May 7, 2020Inventors: James M. Olsen, Michael R. Klardie, Richard T. Stone, Chad Q. Cai, Spencer Fodness-Bondhus, Mark J. Conroy, Timothy R. Abraham, Bruce R. Mehdizadeh, Michael J. Kern, Jay K. Lahti

Patent number: 10556105Abstract: A shield located within an implantable medical lead may be terminated in various ways. The shield may be terminated by butt, scarf, lap, or other joints between insulation layers surrounding the lead and an insulation extension. For lap joints, a portion of an outer insulation layer may be removed and a replacement outer insulation layer is positioned in place of the removed outer insulation layer, where the replacement layer extends beyond an inner insulation layer and the shield. The replacement layer may also lap onto a portion of the insulation extension. Barbs may be located between the replacement layer and the inner insulation layer or the insulation extension. The shield wires have ends at the termination point that may be folded over individually or may be capped with a ring located within one of the insulation layers of the jacket.Type: GrantFiled: May 7, 2018Date of Patent: February 11, 2020Assignee: MEDTRONIC, INC.Inventors: Michael J. Kern, James M. Olsen, Michael R. Klardie, Richard T. Stone, Chad Q. Cai, Spencer Fodness-Bondhus, Mark J. Conroy, Timothy R. Abraham, Brian T. Stolz

Patent number: 10518081Abstract: Medical leads include a lumen body at an end of the lead, and the lumen body includes multiple filar lumens. The lumen body is joined to a lead body, and electrical connectors are longitudinally spaced along the lumen body. Filars within the filar lumens are directed through filar passageways within the lumen body to attach to the electrical connectors on the lumen body. The filar passageways may be aligned with the filar lumens, and slots within the electrical connectors may be aligned with the filar passageways to facilitate assembly. The lumen body may provide additional stiffness to the end of the lead where the lumen body is located to facilitate lead insertion into the medical device. The filar lumens of the lumen body may have a longitudinally straight configuration so that the portions of filars within the filar lumens are held in a longitudinally straight configuration.Type: GrantFiled: October 31, 2017Date of Patent: December 31, 2019Assignee: MEDTRONIC, INC.Inventors: Michael R Klardie, Michael J.

Publication number: 20180339153Abstract: An implantable medical lead has a torsional stiffness and is rotationally coupled to a stylet. Applying rotation directly to the lead in turn causes rotation of the stylet. Where the stylet has a bent tip for purposes of steering the lead, the rotation applied to the lead rotates the bent tip so that the lead can be steered by rotating the lead rather than rotating a hub of the stylet. The rotational coupling may be achieved through one or more features provided for the lead and/or the stylet, such as a feature within a lumen of the lead that mates to a feature along the stylet or a feature of the stylet hub that engages the proximal end of the lead. The torsional stillness of the lead may be provided by adding a feature within the lead body, such as a braided metal wire or an overlapping foil.Type: ApplicationFiled: July 22, 2018Publication date: November 29, 2018Inventors: James M. Olsen, Michael R. Klardie, Richard T. Stone, Chad Q. Cai, Spencer Fodness-Bondhus, Mark J. Conroy, Timothy R. Abraham
