Patent number: 11883282Abstract: A prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be reshaped into an expanded form in order to receive and/or support an expandable prosthetic heart valve therein is disclosed, together with methods of using same. The prosthetic heart valve may be configured to have a generally rigid and/or expansion-resistant configuration when initially implanted to replace a native valve (or other prosthetic heart valve), but to assume a generally expanded form when subjected to an outward force such as that provided by a dilation balloon or other mechanical expander.Type: GrantFiled: November 25, 2019Date of Patent: January 30, 2024Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Visith Chung, Da-Yu Chang, Brian S. Conklin, Grace Myong Kim, Louis A. Campbell, Donald E. Bobo, Jr., Myron Howanec, Jr., David S. Lin, Peng Norasing, Francis M. Tran, Mark Van Nest, Thomas Chien, Harvey H. Chen, Isidro L.

Publication number: 20230233326Abstract: A method comprises inserting a needle into a ventricle of a heart. The needle is configured to deliver a first anchoring element, a second anchoring element, and a tethering suture to the ventricle. The tethering suture is tethered between the first anchoring element and the second anchoring element. The method further comprises penetrating a first leaflet of a heart valve with the needle, penetrating a second leaflet of the heart valve with the needle, deploying the first anchoring element at a distal side of the second leaflet, retracting the needle from the first leaflet and the second leaflet, deploying the second anchoring element at a proximal side of the first leaflet, cinching the tethering suture to cause a desired amount of valve coaptation, and locking the tethering suture.Type: ApplicationFiled: March 24, 2023Publication date: July 27, 2023Inventors: Brian S. Conklin, Maria L. Saravia, Harvey H. Chen, Cindy Woo
