Patent number: 11911269Abstract: A prosthesis can include a collapsible, reexpandable frame comprising first, second, and third sets of struts that define first and second rows of expandable cells. In some embodiments, the struts of the first, second, and third set of struts can be tapered. In some embodiments, the frame can include an intermediate section and an inflow section that is proximal to the intermediate section. The inflow section can include a concave saddle portion that is adjacent the intermediate section, and an outwardly flared portion.Type: GrantFiled: March 7, 2022Date of Patent: February 27, 2024Assignee: MEDTRONIC CV LUXEMBOURG S.A.R.L.Inventors: Padraig Savage, Joseph Callol, Alaena DeStefano, Joshua Dwork, Devin Gosal, Karan Punga, Finn Rinne, Billy Tam

Publication number: 20240058125Abstract: A delivery system for use with a prosthetic heart valve having a stent frame to which a valve structure is attached, includes a shaft assembly including a distal end and a coupling structure disposed near the distal end and configured to be coupled to a distal end of the prosthetic heart valve. The system includes a sheath assembly defining a lumen sized to slidably receive the shaft assembly. The delivery system is configured to transition from a loaded state in which the sheath assembly encompasses the prosthetic heart valve to a deployed state in which the sheath assembly is withdrawn from the prosthetic heart valve. The coupling structure is configured to provide a controlled expansion or contraction of the distal end of the prosthetic heart valve based on longitudinal movement of the distal end of the shaft assembly.Type: ApplicationFiled: October 30, 2023Publication date: February 22, 2024Inventors: Matthew Rust, Padraig Savage, Gianfranco Pellegrini, Finn Rinne

Patent number: 9421601Abstract: A method of manufacturing a stent includes forming a wave form having a plurality of struts and a plurality of crowns. Each crown connects two adjacent struts. The wave form has a central portion and two end portions located on opposite sides the central portion. Some of the struts located in the end portions have lengths longer and/or shorter than an average length of all of the struts of the wave form. The method includes wrapping the wave form about a longitudinal axis to define a plurality of turns so that an end turn is oriented at an angle relative to the longitudinal axis, a second turn is at a first pitch angle that is less than the angle that the end turn is disposed relative to the longitudinal axis, a third turn is at a second pitch angle that is less than the first pitch angle, and a fourth turn is at a third pitch angle that is less than the second pitch angle.Type: GrantFiled: May 12, 2015Date of Patent: August 23, 2016Assignee: Medtronic Vascular, Inc.Inventors: Richard Bliss, Justin Goshgarian, Rui Lam, Padraig Savage, Erik Griswold, Giangranco Pellegrini, Matthew Baldwin, Lance Ensign
