1. A valve, comprising:
- a frame having a first leaflet connection region and a second leaflet connection region;
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.

21. A method, comprising:
-
forming a frame having leaflet connection regions; forming a first leaflet and a second leaflet having integrated flexible support members to provide support to the first leaflet and the second leaflet; coupling the first leaflet and the second leaflet to the leaflet connection regions of the frame to form a valve having surfaces defining a reversibly sealable opening for unidirectional flow of a liquid through the valve; and reversibly joining the valve and a catheter. - View Dependent Claims (22, 23, 24, 25, 26, 27)
