Abstract: A stent delivery device has a handle and a sliding body, the sliding body is slidable with respect to the handle. The handle has a grip and a guide. The sliding body has at least two flange portions extending from the sliding body. The flange portions are offset from one another along the length of the sliding body. The operator can thereby deploy a relatively long stent by first gripping the nearest flange portion and pulling the sliding body toward the handle; subsequently, the operator can reposition his/or finger on the next-nearest flange portion and continue deployment of the stent by pulling the sliding body further toward the handle.

Abstract: An intraluminal prosthesis includes an outer three-dimensional (3D) anti-migration structure that is attached to the outer wall of a fully covered or partially covered stent to prevent migration and still allow stent removal at a later period of time. A method of manufacturing the intraluminal prosthesis includes attaching the anti-migration structure by usage of a polymer such as polyurethane.

Abstract: A medical device consists of a stent having a first surface and a second surface parallel to the first surface; a single expanded polytetrafluoroethylene (ePTFE) layer contacting the first surface of the stent; and an elastomeric layer applied to at least one surface of the stent. In at least one embodiment, the elastomeric layer is silicone. In at least one embodiment, the medical device is manufactured by positioning the ePTFE layer such that a first surface of the ePTFE layer contacts a first surface of the stent to form a stent-ePTFE assembly; and applying an elastomeric solution to the first surface of the ePTFE layer and at least one surface of the stent.

Abstract: A prosthesis that when implanted in the gastrointestinal tract does not impede the normal function of the pyloric sphincter. In some instances, the prosthesis is implanted as part of, or after, a sleeve gastrectomy procedure. The prosthesis includes a stent with an outer surface and a polymeric cover fully covering the outer surface of the stent. The stent includes a proximal stent flange; a proximal stent segment extending distally from the proximal stent flange; and an enlarged stent segment extending distally from the proximal stent segment.

Abstract: In at least one embodiment, the invention is directed to an endoluminal device comprising a stent and a sleeve. In one embodiment, the endoluminal device is implanted in a portion of the gastrointestinal tract. In some embodiments, the stent has a first region and a second region where the first and second regions provide different levels of radial force. In one embodiment, the first region is made from a plurality of first wires having a first diameter and the second region is made from a plurality of second wires having a second diameter which is smaller than the first diameter. In other embodiments, the endoluminal device has at least one engagement mechanism engaging the stent to the sleeve, the endoluminal device to a body lumen, and any combination thereof. In at least one embodiment, the endoluminal device has a wall with at least one opening therein.
