Abstract: A stent and method for treating an end of a pre-woven stent is provided. The method includes providing a pre-woven stent including a plurality of sharp wire ends. The wire ends are arranged in pairs. A separate cap is placed over the ends of the paired wires. The wire ends are secured to the cap, such that the sharp ends are covered by the cap. The cap may have a pair of leg portions that combine to form a curved bend portion. The cap may be flexible. The wire ends may be received in open ends of the cap. The cap may include a pair of legs portions connected by a flexible bridge portion. The caps may be disposed at different axial locations. The caps may be disposed at a single end of the stent, with the opposite end being without sharp ends after being pre-woven. Alternatively, the caps may be applied to both ends of the pre-woven stent having sharp ends at both ends after being pre-woven. The pre-woven stent is preferably a machine woven stent.

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.

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.
