Patent number: 11911264Abstract: A prosthetic spacer assembly includes a spacer body, a first anchor, and a second anchor. The first anchor and the second anchor are each connected to the spacer body. The first anchor is configured to capture a first native valve leaflet between the first anchor and the spacer body. The second anchor is configured to capture a second native valve leaflet between the second anchor and the spacer body. When inside a delivery sheath, the first anchor and the second anchor can extend distally from the spacer body.Type: GrantFiled: September 10, 2020Date of Patent: February 27, 2024Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Mark Chau, Marlowe E.

Publication number: 20230285142Abstract: A system for replacing a native valve of the heart includes a delivery apparatus having a sheath and a prosthetic valve. The prosthetic valve includes a frame having an annular main body, a plurality of ventricular anchors attached to the main body, an atrial anchor attached to an atrial end portion of the main body, and a valve structure disposed within the main body of the frame. The prosthetic valve is disposed within a distal end portion of the sheath in a compressed, delivery state. When the prosthetic valve is deployed from the sheath, the main body of the frame radially expands to a radially expanded state, the ventricular anchors expand to a deployed state alongside the main body of the frame for capturing native leaflets of the native valve, and the atrial anchor expands to a deployed state extending radially outwardly from the main body.Type: ApplicationFiled: May 19, 2023Publication date: September 14, 2023Inventors: Mark Chau, Marlowe E. Patterson, Seung-Beom Yi, Stephen C. Geist, Travis Zenyo Oba

Publication number: 20230190458Abstract: A prosthetic heart valve for implantation at a native heart valve includes a multi-part frame. The multi-part frame includes a cylindrical main body and a ventricular anchor component surrounding the main body. The main body includes a plurality of struts arranged in a lattice pattern. The ventricular anchor component is attached to the main body only at an outflow end of the main body and extends toward an inflow end of the main body. The prosthetic valve further includes a valve structure having three leaflets made from pericardium. The multi-part frame is radially compressible for delivery within a sheath of a delivery catheter and is self-expandable for deployment within an annulus of the native valve. The main body and the ventricular anchor component are formed separately and are attached by a locking mechanism for reducing strain between the main body and the ventricular anchor component.Type: ApplicationFiled: February 13, 2023Publication date: June 22, 2023Inventors: Mark Chau, Marlowe E.

Patent number: 11583396Abstract: A prosthetic apparatus for implantation in a native heart valve includes a main body for placement within the native annulus. The main body is compressible to a radially compressed state for delivery into the heart and is self-expandable from the compressed state to a radially expanded state for implantation. A valve structure is mounted within a lumen of the main body and preferably forms three leaflets made of pericardium. Ventricular anchors are coupled to a ventricular end portion of the main body. The ventricular anchors are adapted to be straightened for delivery to the native heart valve and are biased to spring back to a pre-formed bent shape for capturing the native heart valve leaflets between the main body and the ventricular anchors. An atrial sealing member may be provided along an atrial portion of the main body for impeding the flow of blood between the main body and the native annulus.Type: GrantFiled: August 31, 2020Date of Patent: February 21, 2023Assignee: Edwards Lifesciences CorporationInventors: Mark Chau, Marlowe E.
