Patent number: 11969344Abstract: Disclosed herein are representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve to a deficient valve. In one embodiment, for instance, a support structure and an expandable prosthetic valve are advanced through the aortic arch of a patient using a delivery system. The support structure is delivered to a position on or adjacent to the surface of the outflow side of the aortic valve (the support structure defining a support-structure interior). The expandable prosthetic valve is delivered into the aortic valve and into the support-structure interior. The expandable prosthetic heart valve is expanded while the expandable prosthetic heart valve is in the support-structure interior and while the support structure is at the position on or adjacent to the surface of the outflow side of the aortic valve, thereby causing one or more native leaflets of the aortic valve to be frictionally secured between the support structure and the expanded prosthetic heart valve.Type: GrantFiled: December 9, 2019Date of Patent: April 30, 2024Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Christopher J. Olson, Glen T. Rabito, Dustin P. Armer, Minh T. Ma, Devin H. Marr, Cheng-Tung Huang, Hiroshi Okabe, Kevin M. Stewart, Alison S. Curtis, Philip P. Corso, Jr.

Publication number: 20230255768Abstract: Disclosed herein is an expandable sheath that can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. The disclosed herein sheath can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some aspects can include a sheath comprising an inner layer comprising a reinforcing layer comprising a plurality of struts that can be encapsulated within a polymer layer comprising a tether portion and an outer layer disposed over the inner layer. The disclosed sheath is configured to locally expand from a predetermined first diameter d1 to an expanded second diameter d2 during application of a radial outward force by passage of a medical device through the sheath.Type: ApplicationFiled: April 25, 2023Publication date: August 17, 2023Inventors: Ilan Tamir, David A. Rezac, Devin H. Marr, Jack Sattell, Michelle Riches, Bridget Bergstrom, Matthew Lapointe

Such aspects can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some aspects can include a sheath comprising an inner layer comprising a reinforcing layer rolled into a spiral slidable configuration and encapsulated within a polymer layer comprising a tether portion and an outer layer disposed over the inner layer. The disclosed sheath is configured to locally expand from a predetermined first diameter d1 to an expanded second diameter d2 during application of a radial outward force by passage of the medical device through the sheath.Type: ApplicationFiled: April 21, 2023Publication date: August 17, 2023Inventors: Ilan Tamir, Devin H.

Patent number: 11696827Abstract: Disclosed herein are representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve assembly. In embodiments, a prosthetic heart valve assembly, including a self-expandable support structure and a self-expanding heart valve, are advanced through the aortic arch of a patient using a delivery system. The support structure, which includes a plurality leaflet retaining arms, is at least partially expanded and positioned on or adjacent to the outflow side of the aortic valve. The prosthetic heart valve is positioned in the aortic valve. The prosthetic heart valve is expanded while it is within an interior of the support structure and while the support structure is positioned on or adjacent to the outflow side of the aortic valve, thereby causing one or more native leaflets of the aortic valve to be frictionally secured between the arms of the support structure and the expanded prosthetic heart valve.Type: GrantFiled: November 16, 2021Date of Patent: July 11, 2023Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Christopher J. Olson, Glen T. Rabito, Dustin P. Armer, Minh T. Ma, Devin H. Marr, Cheng-Tung Huang, Hiroshi Okabe, Kevin M. Stewart, Alison S. Curtis, Philip P. Corso, Jr.
