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.

Abstract: Methods and apparatuses of atraumatic stents with likely reduced rates of tissue perforation are provided. The stents of the invention have crowns with crown tips having apexes made of a radial force reducing material. The apexes are soft and flexible and reduce the radial force at the crown relative to the stent body allowing the crowns to collapse with greater ease compared to the central portion of the stent.

Abstract: A prosthesis and a method for implantation of the prosthesis into a bodily lumen are provided. The prosthesis includes a body having a proximal portion, a distal portion, an outer surface and a lumen extending therethrough defining an inner surface. The outer surface includes a first plurality of protrusions, the first plurality of protrusions are adapted to increase the friction force between the prosthesis and the bodily lumen, the first plurality of protrusions forming a first pattern on at least a portion of the outer surface of the body.

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.
