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: 20210282757Abstract: Valvular implants and blood vessel closure devices herein are configured to be positioned in the heart and to block regurgitant blood flow from the heart into blood vessels supplying blood to the heart. The valvular implants can have a cover, a membrane, a valve, a resilient frame, and/or other features. Some valvular implants can have anchors to be positioned in the blood vessels, such as in pulmonary veins, and can anchor the implant to the heart wall. Various embodiments of covers and/or membranes act as valves contracting and expanding, to alternately permit and block blood flow. The valvular implants can cover one or more blood vessels, such as one, two, three, or four pulmonary veins, and can also be configured and implanted to block an appendage to the heart, such as the left atrial appendage.Type: ApplicationFiled: May 28, 2021Publication date: September 16, 2021Inventors: Boaz Manash, Eitan Atias, Liron Tayeb, Amir Blumenfeld, David Maimon, Eyal Leiba
