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 is provided that includes an inner elongate shaft with a lumen and an outer elongate shaft with a lumen, where the inner elongate shaft coaxially extends at least partially within the lumen of the outer elongate shaft. The stent delivery system also a pull member movably disposed along the the inner elongate shaft and first and second restraining members removably secured to the pull member. The stent delivery system also includes a self-expanding stent having an expanded configuration and a collapsed configuration, where the first restraining member is secured to a first portion of the self-expanding stent and the second restraining member is secured to a second portion of the self-expanding stent, thereby securing the self-expanding stent about the outer elongate shaft. Movement of the inner and elongate shafts relative to each other in a first direction applies a tension to the first and second restraining members to move the self-expanding stent to the collapsed configuration.

Abstract: The present disclosure relates to stents and methods of delivering and deploying the same. The stents include fasteners about their periphery and when the stent is radially compressed, the fasteners come into alignment such that a device may be placed through openings in the fasteners to hold the stent in the radially compressed configuration. When the device is removed from the openings, the stent may expand.
