Abstract
A prosthesis and a method for making a 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 and further includes a valve operably connected to the body. The valve has a distal end including a first portion of a surface of the valve lumen and a second portion of the surface that contact each other and form a seal in a closed configuration. The distal end of the valve is formed such that the first portion and the second portion of the surface of the valve lumen contact each other and the distal end is configured to open in response to a pressure that is greater than atmospheric pressure.
