US Patent 11654019 Replacement heart valves and their methods of use and manufacture

A prosthetic valve has a support structure that meets with a plurality of leaflets capable of transitioning between open and closed states. The support structure can include a base frame with a polymer coating and the leaflets can be artificial. The interface between the support structure and each leaflet can be at least partially convex when viewed from an exterior of the support structure along a normal to a plane formed by a central axis of the support structure and a central axis of the leaflet.
