A recently granted patent (Publication Number: US11903823B2) discloses a prosthetic heart valve featuring an annularly collapsible and re-expandable supporting structure with a flared section at the inflow end. The valve includes a plurality of leaflets allowing blood flow in one direction, an inner cuff on the luminal surface, and an outer cuff on the abluminal surface of the supporting structure in the flared section. The outer cuff is affixed to the inner cuff and the supporting structure, covering expandable cells and the inflow edge of the supporting structure.

Furthermore, the prosthetic heart valve described in the patent includes specific configurations such as the use of biological tissue for the inner and outer cuffs, a self-expanding supporting structure, and a skirt flare in the annulus section. The leaflets in the valve have end members joined to the supporting structure, ensuring proper blood flow direction. The outer cuff covers expandable cells in the annular row and is affixed to both the inner cuff and the supporting structure, providing structural integrity. These features aim to enhance the functionality and durability of the prosthetic heart valve, offering potential benefits in terms of patient outcomes and long-term performance.
