Publication number: 20230355378Abstract: Embodiments of a prosthetic heart valve are disclosed. An implantable prosthetic valve may be radially collapsible to a collapsed configuration and radially expandable to an expanded configuration. The prosthetic valve may comprise an annular frame, a leaflet structure positioned within the frame and a plurality of outer skirts positioned around an outer surface of the frame, each outer skirt comprising an inflow edge secured to the frame and an outflow edge secured at intervals to the frame. The plurality of outer skirts may include a first outer skirt and a second outer skirt, wherein in the expanded configuration the first and second outer skirts include openings unsecured to the frame between the intervals. The inflow edge of the first annular outer skirt may be secured to the frame with sutures including radiopaque material. The first annular outer skirt may include radiopaque dye.Type: ApplicationFiled: July 17, 2023Publication date: November 9, 2023Applicant: EDWARDS LIFESCIENCES CORPORATIONInventors: Hanoch Cohen-Tzemach, Tamir S.

Publication number: 20230111680Abstract: Embodiments disclosed herein may be directed to devices, systems, and methods for addressing leaflets within a patient's body, including displacement of such leaflets. The leaflets may be of a native heart valve, or may be of a prosthetic heart valve that has been previously implanted within the patient's body. The leaflets may be displaced to reduce the possibility of the leaflets blocking access to structures within the patient's body, which may comprise cardiac structures such as coronary ostia, for example. As such, a reduced possibility of maladies caused by blockage of the cardiac structures may result.Type: ApplicationFiled: December 13, 2022Publication date: April 13, 2023Inventors: Joseph Mordechai Leichner, Hanoch Cohen-Tzemach, Jeong Soo Lee

Publication number: 20230086571Abstract: Methods and tools for folding and/or capturing leaflets of a heart valve are disclosed herein. Prior to or during installing of a prosthetic heart valve, part of a leaflet of an existing valvular structure can be positioned distally and/or folded upon itself. The existing valvular structure may be a native heart valve or a previously-implanted prosthetic heart valve. When the existing valvular structure is at the aortic position, the prosthetic heart valve can be subsequently installed within the existing valvular structure such that the leaflet is maintained in a location that avoids obstructing blood flow to one or more of the coronary arteries.Type: ApplicationFiled: November 23, 2022Publication date: March 23, 2023Inventors: Ofir Witzman, Eitan Atias, Hanoch Cohen-Tzemach, David Maimon

Publication number: 20230077068Abstract: Methods and tools for implanting prosthetic heart valves and modifying leaflets of an existing valvular structure in a subject are disclosed herein. Prior to or during implantation of the prosthetic heart valve within the existing valvular structure, each tool can be provided in the ascending aorta (or equivalent thereof) of a subject and can be used to pierce, lacerate, slice, tear, cut or otherwise modify a leaflet or commissure of the existing valvular structure. The existing valvular structure can be a native aortic valve or other native heart valve, or a previously-implanted prosthetic heart valve. The modification can avoid, or at least reduce the likelihood of, issues that leaflets of the existing valvular structure might otherwise cause once the prosthetic heart valve has been fully installed, for example, obstruction of blood flow to the coronary arteries and/or improper valve mounting due to a non-circular cross-section.Type: ApplicationFiled: September 15, 2022Publication date: March 9, 2023Inventors: Ilan Tamir, David Maimon, Hanoch Cohen-Tzemach, Adva Alon, Amir Keret, Eyal Leiba, Boaz Manash, Sean Chow, Ziv Yohanan, Shay Zarneger

Publication number: 20220202569Abstract: A prosthetic valve having a frame, a leaflet structure having leaflets forming a primary valve mounted inside the frame, and at least one secondary valve is disclosed. The secondary valve can have a valve element with stationary portion and a detached portion, and at least one aperture in at least one leaflet. The secondary valve can be formed by a portion of at least one leaflet.Type: ApplicationFiled: March 16, 2022Publication date: June 30, 2022Applicant: Edwards Lifesciences CorporationInventors: Tomer Saar, Hanoch Cohen-Tzemach, Nadav Ben Zaken

Publication number: 20210282922Abstract: A radially expandable prosthetic valve can comprise an annular frame, at least one expansion mechanism and a cord. The annular frame can be radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration. The expansion mechanism can comprise a first member attached to the frame at a first location and a second member attached to the frame at a second location axially spaced from the first location. The cord can extend at least partially along the expansion mechanism in a first direction, be reeved around a portion of the second member, and extend at least partially along the expansion mechanism in a second direction opposite the first direction. Applying a proximally directed force to a first portion of the cord can cause the second member to move relative to the first member, which can cause the frame to foreshorten axially and expand radially.Type: ApplicationFiled: June 3, 2021Publication date: September 16, 2021Applicant: Edwards Lifesciences CorporationInventors: Hanoch Cohen-Tzemach, Tamir S. Levi, Yair A. Neumann, Tomer Saar, Gregory Rinberg
