Application: Prosthetic heart valve frames with radially offset commissure portions (Patent ID: US20240148497A1)
The patent filed by Edwards Lifesciences Corp. describes annular frames for prosthetic heart valves with commissure portions that are radially offset and flexible, allowing for radial inward and outward flexing relative to the rest of the frame. These commissure portions can be cantilevered from the frame, enhancing the positioning of leaflets and the overall effectiveness of the valve. Additionally, lateral arms are included to couple the upper ends of the commissure portions to adjacent apices, aiding in pulling them in at larger diameters.
The claims detail the specific configurations and features of the frame for the prosthetic heart valve, including the radial compressibility and expandability of the frame, the coupling of commissure portions to the interconnected struts, and the presence of lateral arms to facilitate radial inward movement of the commissure portions. The prosthetic heart valve itself includes a leaflet valve structure secured to the commissure portions, with the commissures positioned radially outwardly relative to the interconnected struts. The delivery apparatus described in the patent is designed to deliver the prosthetic heart valve to an implant location within the heart and facilitate radial expansion to the desired configurations, utilizing features such as shape memory material, self-expansion mechanisms, inflatable balloons, and axially oriented screws for controlled expansion.
