Patent number: 11400282Abstract: In some examples, an implantable medical device (IMD) that includes a pulse generator comprising a housing, electrodes, and circuitry configured to deliver cardiac pacing via the electrodes. The IMD may further include a lead including at least one of the electrodes, an elongate body, a fixation helix, and a connector segment. A width of the helix transverse to a longitudinal axis of the lead is greatest at a distal end of the helix. A proximal end of the elongate body may be connected to a distal end of the pulse generator, and the helix may be attached to a distal end of the elongate body. The pulse generator may include a first connector tab. A distal end of the connector segment may be configured to receive the proximal end of the elongate body and a proximal end of the connector segment may include at least one second connector member configured to engage the first connector tab.Type: GrantFiled: November 12, 2019Date of Patent: August 2, 2022Assignee: Medtronic, Inc.Inventors: Mark T. Marshall, Teresa A. Whitman, Carla Pfeiffer, Thomas A. Anderson, Jean Rutten, Paul Adams, Antoine Camps, Richard Cornelussen, Ralph Leinders

Publication number: 20220096824Abstract: Methods and systems for positioning a leadless pacing device (LPD) in cardiac tissue are disclosed. A delivery device is employed that comprises a proximal end, a distal end and a lumen therebetween sized to receive the LPD. The LPD has a leadlet extending therefrom that includes a means to fixate the leadlet to tissue. The delivery device comprises an introducer to introduce the LPD into the lumen of the delivery device. The LPD is loaded in the distal end of the lumen of the delivery device. The leadlet extends proximally from the LPD while the fixation means extends distally toward the LPD. A LPD mover is configured to advance the LPD out of the delivery device. A leadlet mover is configured to advance the leadlet out of the lumen delivery device and cause the leadlet to engage with cardiac tissue.Type: ApplicationFiled: December 10, 2021Publication date: March 31, 2022Inventors: Ronald A. Drake, Kenneth C. Gardeski, Carla Pfeiffer, Kevin R. Seifert, Lester O. Stener, Matthew D. Bonner

Patent number: 11207504Abstract: The present disclosure is directed to a shuttle apparatus for detachably joining a catheter to a guidewire so that the joined catheter, extending alongside the guidewire, is in sliding engagement with the guidewire without extending around the guidewire. The apparatus comprises a collar member sized for mounting in sliding engagement around a length of the guidewire, the collar member having a longitudinal axis that approximately aligns along the length, when mounted thereabout, the length being defined between a proximal-most point of the guidewire and a distal point of the guidewire, the distal point being offset proximally from a distal-most point of the guidewire. The apparatus further comprises a plug member coupled to the collar member, the plug member having a longitudinal axis, and the plug member being sized to fit within an opening of the catheter for detachable engagement therewith.Type: GrantFiled: January 17, 2018Date of Patent: December 28, 2021Assignee: Medtronic, Inc.Inventors: Ronald A. Drake, Matthew D. Bonner, Trent M. Fischer, Carla Pfeiffer, Brian P. Colin, Lester O. Stener
