Publication number: 20240115375Abstract: A prosthetic heart valve includes an annular frame that is radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration. The frame has a plurality of circumferentially extending rows of angled struts, each row of angled struts comprising angled struts arranged in a zig-zag pattern. The prosthetic heart valve further includes a leaflet structure positioned within the frame and secured thereto, and an outer sealing member mounted outside of the frame. The sealing member has an undulating outflow edge portion forming a plurality of triangular projections that are connected to and shaped to correspond to the zig-zag pattern of one of the rows of angled struts. The outer sealing member is sized to fit snugly against the outer surface of the frame when the frame is in the expanded configuration.Type: ApplicationFiled: December 15, 2023Publication date: April 11, 2024Inventors: Lien Huong Thi Hoang, Son V. Nguyen, Hien Tran Ngo, Vivian Tran, Russell T. Joseph, Dinesh L. Sirimanne, Kevin D. Rupp, Diana Nguyen-Thien-Nhon

Patent number: 11883281Abstract: A prosthetic heart valve includes an annular frame that has an inflow end and an outflow end and is radially compressible and expandable between a radially compressed configuration and a radially expanded configuration. The prosthetic heart valve further includes a leaflet structure positioned within the frame and secured thereto, and an outer sealing member mounted outside of the frame and adapted to seal against surrounding tissue when the prosthetic heart valve is implanted within a native heart valve annulus of a patient. The sealing member can include a mesh layer and pile layer comprising a plurality of pile yarns extending outwardly from the mesh layer.Type: GrantFiled: March 30, 2022Date of Patent: January 30, 2024Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Lien Huong Thi Hoang, Son V. Nguyen, Hien Tran Ngo, Vivian Tran, Russell T. Joseph, Dinesh L. Sirimanne, Kevin D. Rupp, Diana Nguyen-Thien-Nhon

Publication number: 20230248512Abstract: Devices and methods for reinforcing a tissue-based heart valve are provided. A reinforced tissue valve can provide structure and rigidity to withstand stresses that occur within the vasculature. In some instances, thickened tissue provides structure or rigidity. In some instances, a biocompatible filler is utilized within folded, rolled, or layered tissue. In some instances, a mesh is included with a reinforced tissue valve for further strength. In some instances, a mesh frame is utilized along the sidewall of a tissue-based heart valve. In some instances, a leaflet assembly is provided within a conduit having thickened tissue at the leaflet commissures.Type: ApplicationFiled: April 14, 2023Publication date: August 10, 2023Inventors: Tara J. Tod, Mark Van Nest, Kiem Bao Nguyen, Liqiong Gui, Lien Huong Thi Hoang, Son V. Nguyen, Hao Shang
