Patent Issued for Prosthetic heart valve leaflet assemblies and methods (USPTO 12121435).

A patent has been issued for prosthetic heart valve leaflet assemblies and methods by inventors Noam Nir and Elena Sherman, with Edwards Lifesciences Corporation as the assignee. The patent describes methods for assembling prosthetic heart valves using leaflet assemblies supported by an expandable annular frame, offering simple and cost-effective ways to mount the leaflet assembly to the heart valve. The innovation aims to reduce the risk of leaflet tearing by avoiding stitching sutures through dynamic portions of the leaflets. This development could potentially improve the stability and reliability of prosthetic heart valves during assembly and implantation procedures. [Extracted from the article]
