REINFORCED VALVE

摘要

The embodiments disclosed herein relate to a valve that is configured to be coupled to a stent. The valve may include a body, a rim, and an opening. The opening may include three or more leaflets that are configured to open and close. The valve may further include a reinforcement member that may be coupled to the rim. The reinforcement member may be formed of a mesh or mesh-like material or may be made of a polymeric film. The reinforcement member may aid in preventing a stitching element from tearing through the rim of the valve and may be coupled to the inner diameter or the outer diameter of the rim. The reinforcement member may also be molded within the rim.

主权项

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 coupled to the substantially cylindrical-shaped rim, the reinforcement member being constrained to the substantially cylindrical-shaped rim.
