Claim Text:
1. A valve for placement in a body lumen, comprising: a body; a substantially cylindrical-shaped rim disposed at a first end of the valve, the substantially cylindrical-shaped rim having a proximal end and a distal end; an opening disposed at a second end of the valve, wherein the opening comprises one or more leaflets, the opening having a closed configuration in which the leaflets are closed, an antegrade open configuration in which the leaflets are opened in response to an antegrade force, and a retrograde open configuration in which the leaflets are opened in response to a retrograde force; and a reinforcement member molded within the substantially cylindrical-shaped rim, the reinforcement member being constrained to the substantially cylindrical-shaped rim such that the reinforcement member is disposed between the proximal end and the distal end of the substantially cylindrical-shaped rim, the reinforcement member comprising a mesh material having a plurality of openings configured to receive a stitching element, wherein the reinforcement member is configured to prevent the stitching element from tearing through the substantially cylindrical-shaped rim in response to the antegrade force and the retrograde force, and wherein the reinforcement member is formed from a different material than the substantially cylindrical-shaped rim.
