Abstract
A prosthesis and a method of manufacturing the prosthesis for controlling flow through a bodily lumen are provided. The prosthesis includes a body having a proximal portion, a distal portion and a lumen extending therethrough. The prosthesis also includes a valve operably connected to the body. The valve has a proximal portion, a distal portion and a lumen extending through the valve, where the valve lumen is connected to the body lumen. The valve is configured to be closed in the absence of an antegrade pressure and a retrograde pressure, the retrograde pressure being greater than the antegrade pressure. The valve includes a material portion operably connected to the valve, the material portion providing increased stiffness to the valve relative to the valve alone, wherein the material portion is configured to facilitate self-reversion of the valve to the closed configuration.
