Patent number: 11744701Abstract: A prosthetic heart valve comprises a radially collapsible and expandable annular frame and a leaflet structure comprising three leaflets. Each leaflet has an upper edge portion, a curved lower edge portion and two side flaps, wherein each side flap is connected to an adjacent side flap of another leaflet to form commissures of the leaflet structure, with each commissure being attached to the frame. An annular inner sleeve comprises three U-shaped portions positioned along the curved lower edge portions of the leaflets. An annular outer sleeve extends around are outer surface of the frame, wherein the outer sleeve is made of pericardium. The frame is made of Nitinol and the prosthetic valve can be radially crimped to a radially collapsed configuration inside a sheath for delivery into a patient's body and self-expand to a radially expanded configuration when released from the sheath inside the patient's body.Type: GrantFiled: September 11, 2020Date of Patent: September 5, 2023Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Ilia Hariton, Netanel Benichou, Yaacov Nitzan, Bella Felsen, Diana Nguyen-Thien-Nhon, Rajesh A.

Patent number: 11730597Abstract: An assembly for replacement of a native aortic heart valve includes a radially collapsible prosthetic heart valve and a delivery apparatus. The prosthetic heart valve includes an annular frame with attachment posts, wherein each of the posts has an axial post portion and a transverse post portion having a greater circumferential dimension than the axial post portion. The delivery apparatus includes an inner shaft with a valve connection portion for releasably coupling to the attachment posts and an outer shaft having a sheath for maintaining the prosthetic heart valve in a radially compressed state. Rotation of a control knob on a handle causes the sheath to retract for uncovering a portion of the prosthetic heart valve. Further rotation of the control knob allows the posts to decouple from the delivery apparatus such that the prosthetic heart valve self-expands to a fully expanded state.Type: GrantFiled: January 26, 2023Date of Patent: August 22, 2023Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: David Alon, Netanel Benichou, Oded Meiri
