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: 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 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.

Abstract: A delivery assembly and methods for accurately positioning a stent within a body lumen are disclosed. The delivery assembly comprises a stent releasably attached to the distal end of an inner catheter. A handle at the proximal end of the assembly is operatively connected to the proximal end of an outer catheter and is configured for imparting axial movement to the outer catheter. A sheath is fixed to the handle or inner catheter and disposed about at least a portion of the outer catheter. The sheath comprises indicia visible to the user of the assembly to identify a particular measured distance from a selected point on the sheath to a selected point on one or more components of the delivery device. The inner catheter and sheath are fixed components that do not move relative to each other during axial movement of the outer catheter.

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 medical device and a method for controlling flow through a bodily lumen are provided. The medical device includes a valve device positioned within the bodily lumen. The valve device includes a movable member movable within the bodily lumen and a magnetic portion operably connected to the movable member to facilitate positioning the movable member in a first configuration. The magnetic portion has a magnetic attraction to another magnetic portion or a portion of the valve device having a charge opposite a charge of the magnetic portion. The valve device is movable from the first configuration substantially closing the bodily lumen in the presence of a first pressure within the bodily lumen to a second configuration in response to a second pressure that is greater than the first pressure. The valve device is open in the second configuration and the movable member is normally positioned in the first configuration.
