  • Publication number: 20190262151
    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.

  • Publication number: 20190159879
    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.

  • Patent number: 10299950
    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.
