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: A stent delivery system includes an elongate shaft including a proximal portion, a distal portion, at least one lumen extending at least partially therethrough, and a stent receiving portion on the distal portion of the elongate shaft. A stent is positioned on the stent receiving portion of the elongate shaft, the stent having a first configuration and a second configuration. A sheath is positioned longitudinally around the inner elongate shaft, the inner elongate shaft extending coaxially at least partially within the lumen of the outer sheath, the outer sheath moveably positionable relative to the outer elongate shaft. A proximal constraining arrangement is engaged with a proximal end of the stent. A distal constraining arrangement is engaged with a distal end of the stent. A handle assembly is connected to the proximal constraining arrangement, the distal constraining arrangement, and the outer sheath. A brake assembly is positioned within the handle assembly.

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.
