1. A valve, comprising:
- a frame having a first leaflet connection region, a second leaflet connection region, and a longitudinal axis;
a first leaflet coupled to the first leaflet connection region and the second leaflet connection region; and
a second leaflet coupled to the first leaflet connection region and the second leaflet connection region, wherein the first leaflet and the second leaflet have integrated flexible support members to provide support to the first leaflet and the second leaflet, the first leaflet connection region and the second leaflet connection region having surfaces defining a reversibly sealable opening for unidirectional flow of a liquid through the valve,wherein each of the integrated flexible support members are circumferentially disposed about the longitudinal axis and support the first leaflet and the second leaflet;
wherein the second material of the integrated flexible support members includes spun-fibers of a ceramic.
