Patent number: 11931567Abstract: In some examples, a tether head assembly of a delivery system includes an inner retainer and an outer retainer that defines an aperture comprising a receptacle configured to receive an attachment member of a medical device, a passageway, and a groove. The inner retainer is movable within the groove between a second position in which the passageway is dimensioned to receive the attachment member and a first position in which the passageway is dimensioned to prevent passage of the attachment member. In some examples, a tether handle assembly defines a channel, a force transmitter within the channel, a slidable member partially received within a first end of the channel and a button partially received within a second end of the channel. Distally-directed force applied to the button may cause the force transmitter to apply proximally-directed force to the slidable member, moving the slidable member and an attached pull wire proximally.Type: GrantFiled: May 12, 2022Date of Patent: March 19, 2024Assignee: Medtronic, Inc.Inventors: Ronald A. Drake, Lester O. Stener, Brian P. Colin

Patent number: 11819699Abstract: VfA cardiac therapy uses an implantable medical device or system. The implantable medical device includes a tissue-piercing electrode implanted in the basal and/or septal region of the left ventricular myocardium of the patient's heart from the triangle of Koch region of the right atrium through the right atrial endocardium and central fibrous body. The device may include a right atrial electrode, a right atrial motion detector, or both. The device may be implanted completely within the patient's heart or may use one or more leads to implant electrodes in the patient's heart. The device may be used to provide cardiac therapy, including single or multiple chamber pacing, atrioventricular synchronous pacing, asynchronous pacing, triggered pacing, cardiac resynchronization pacing, or tachycardia-related therapy. A separate medical device may be used to provide some functionality for cardiac therapy, such as sensing, pacing, or shock therapy.Type: GrantFiled: December 22, 2021Date of Patent: November 21, 2023Assignee: Medtronic, Inc.Inventors: Zhongping Yang, Thomas A.

Patent number: 11357484Abstract: An improved assembly for securing an implantable medical device for retrieval from an implant site includes a plurality of snares, wherein distal openings of a first snare carrier lumen and a second snare carrier lumen have a pre-set offset established therebetween. First and second snare shafts, to which first and second snare loops are coupled, respectively, extend within the corresponding snare carrier lumens such that each loop is located in proximity to the corresponding distal opening of the lumen. The pre-set offset allows an operator to simultaneously position the snare loops around the device; and, when the operator retracts the snare shafts to collapse the snare loops until the loops fit snuggly around the device, the pre-set offset can help to align the device for retrieval.Type: GrantFiled: March 29, 2018Date of Patent: June 14, 2022Assignee: Medtronic, Inc.Inventors: Colin W. Meade, Paula McDonnell, Francis D. McEvoy, Rónán Wood, Kealan E. O'Carroll, Kenneth C. Gardeski, Ronald A. Drake, Kevin R. Seifert, Brian P. Colin, Pierce Vatterott
