Patent number: 11617649Abstract: Transcatheter delivery systems, delivery catheters and associated methods for percutaneous delivery of prosthetic mitral valves using a retrograde approach are disclosed herein. A heart valve delivery system configured in accordance herewith includes a delivery catheter having an elongated tubular component and an articulation assembly at a distal end thereof. The articulation assembly includes an arm portion coupled to the tubular component by an elbow or hinge portion. In a closed, delivery state, the elbow portion positions the arm portion generally parallel to the tubular component for delivery of the delivery catheter through the vasculature. In an open, deployed state, the elbow portion positions the arm portion in a non-axial direction with respect to a longitudinal axis of the tubular component for orienting and positioning a prosthetic valve device carried by the arm portion, e.g., within the native mitral valve region.Type: GrantFiled: June 17, 2020Date of Patent: April 4, 2023Assignee: MEDTRONIC VASCULAR, INC.Inventors: Barry O'Connell, Patrick Griffin, Michael Bateman, William Haynes

Patent number: 11559663Abstract: A catheter may include an elongate body extending from a proximal end to a distal end and defining a lumen; a push member mechanically coupled to the proximal end of the elongate body; and a slidable push grip disposed about an outer perimeter of the push member. The slidable push grip is controllably engageable with the push member. When the slidable push grip is in an engaged state with the push member, the slidable push grip transmits an axial force to the push member to enable the push member to transmit the axial force to the elongate body. When the slidable push grip is in a disengaged state with the push member, the slidable push grip is movable axially in at least one direction along a length of the push member while transmitting substantially no axial force to the push member.Type: GrantFiled: June 5, 2019Date of Patent: January 24, 2023Assignee: MEDTRONIC VASCULAR, INC.Inventors: James Hannon, Joanna Cunniffe, Mick Donegan, David Gannon, Maria Larkin, Francis Denis McEvoy, Conor McNamara, Barry O'Connell
