  • Patent number: 11376123
    Abstract: Prosthetic valves are provided with a leaflet assembly having at least one leaflet attached to a supporting element, which leaflet has a free margin that can move between a first position wherein the free margin is flexed away from a closure surface to allow body fluid to flow through the valve, and a second position wherein the free margin abuts the closure surface to close the valve, and wherein the leaflet, without pulsatile load on the valve, can form a coaptation height H of more than 0.1 mm along the length of the free margin. Such prosthetic valve provides good performance during prolonged time, and can be made using various materials for the leaflets.
    Type: Grant
    Filed: December 3, 2019
    Date of Patent: July 5, 2022

  • Patent number: 10524902
    Abstract: Prosthetic valves are provided with a leaflet assembly having at least one leaflet (3) attached to a supporting element (2), which leaflet has a free margin that can move between a first position wherein the free margin is flexed away from a closure surface (700) to allow body fluid to flow through the valve, and a second position wherein the free margin abuts the closure surface to close the valve, and wherein the leaflet, without pulsatile load on the valve, can form a coaptation height H of more than 0.1 mm along the length of the free margin. Such prosthetic valve provides good performance during prolonged time, and can be made using various materials for the leaflets. The invention also relates to a leaflet assembly for use in a prosthetic valve, and to methods of making the prosthetic valve, including making the leaflet assembly.
