Patent number: 11701228Abstract: A system for treating valvular regurgitation in a heart valve includes a flexible canopy and an elongated tether including an elastic portion and an inelastic portion. When the system is in a deployed configuration, a proximal end of the flexible canopy is coupled to an annulus of the heart valve and a distal end of the elongated tether is coupled to a ventricle. The flexible canopy is configured to overlay a first native leaflet of the heart valve, and tension on the elongated tether is applied and/or adjusted to prevent the first leaflet from prolapsing, to maximize coaptation of the flexible canopy with a second native leaflet of the heart valve, and to minimize regurgitation of the heart valve.Type: GrantFiled: June 4, 2021Date of Patent: July 18, 2023Assignee: MEDTRONIC VASCULAR, INC.Inventors: Matthew Genovese, Jeffrey Sandstrom, Russell Pribanic, Thomas McPeak, Vania Lee, Dermot O'Brien, James Calvin Allan

Patent number: 8864676Abstract: An implantable medical device, such as a sensor for monitoring a selected internally detectable physiological parameter of a patient, is attached to a fixation member that is deployable within the patient to position and orient the sensor to enable it to perform its function. The fixation member may be configured to lie in a single plane when deployed or may be tubular in shape. The attachment of the housing and fixation member includes providing the fixation member with a linear attachment strut that is non-circular in cross section and providing the housing with external members that define an elongate channel, non-circular in cross section and receptive to the attachment strut. The attachment strut can be inserted transversely into the channel and the external member can be crimped over the strut to secure the housing and fixation member together.Type: GrantFiled: April 20, 2011Date of Patent: October 21, 2014Assignee: Medtronic Vascular, Inc.Inventors: Rudy Beasley, Erik Griswold, James Calvin Allan, George Patras, Kamal Deep Mothilal, Albert Dunfee

Patent number: 8727996Abstract: A delivery device for implanting a medical device that includes an expandable fixation member adapted to fix the position of the medical device within a lumen of a human body. The delivery device has an inner shaft rotatably disposed in a tubular outer shaft. A retention member is secured to and rotatable with the inner shaft and has a free end and a retainer portion adapted to protrude outwardly through an exit aperture in the outer shaft to extend circumferentially about the exterior of the outer shaft. The fixation member of the medical device may be retained on the tubular shaft in a low profile configuration by the outwardly protruding retainer portion and may be released to expand upon retraction of the retainer portion in response to rotation of the inner shaft.Type: GrantFiled: April 20, 2011Date of Patent: May 20, 2014Assignee: Medtronic Vascular, Inc.Inventors: James Calvin Allan, Don Tran, Erik Griswold, Rudy Beasley, Arvind Srinivas
