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: A stent delivery device is provided that includes an outer tubular member, an intermediate tubular member disposed and slidable within a lumen of the outer tubular member, and a plurality of elongate members slidable within the intermediate tubular member. The plurality of elongate members have distal end structures that are moveable between a stent retaining configuration to selectively retain a stent and a stent releasing configuration to selectively release 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: An endoscopic stent for implantation in a patient after sleeve gastrectomy or biliopancreatic diversion with duodenal switch or biliopancreatic diversion with duodenal switch comprising a stent portion, the stent portion comprising a proximal end portion, the proximal end portion defined by a length of about 50 mm to about 200 mm, an enlarged middle portion, a middle portion having an enlarged diameter relative to the proximal end portion and the distal end portion and defined by a length of about 20 mm to about 80 mm, and a distal end portion and a polymeric sleeve portion engaged to and extending distally from the distal end portion of the stent.

Abstract: A medical device and related method of use for cutting tissue is described. The device includes an elongate tubular member having a proximal end, a distal end, and first and second lumens extending between the proximal and distal ends. The device further includes a first elongate arm having a third lumen extending distally from the first lumen and a second elongate arm having a fourth lumen extending distally from the second lumen. A cutting element extends from the third lumen of the first arm to the fourth lumen of the second arm, such that the cutting element is slidably disposed in at least one of the third and fourth lumens.

Abstract: An implantable prosthesis device is disclosed. The prosthesis device comprises one or more compartments bounded by a substantially closed porous envelope made at least in part of non-woven polymer fibers, and a filler structure at least partially filling the compartment(s) and being made, at least in part, of non-woven swellable polymer fibers.

Abstract: An ablation catheter system for capturing and removing necrotic tissue and thrombi generated during an ablative procedure is disclosed. The catheter typically includes an elongate member, a filtration assembly disposed within the distal region, and an ablation instrument at the distal end. Alternatively, the ablation instrument is carried on the distal end of an ablation catheter, which is disposed within a lumen of the catheter system. The catheter may further include an aspiration port and lumen. Methods of using the devices in preventing distal embolization during ablative procedures are disclosed.

Abstract: A balloon arterial cannula and methods for filtering blood. The devices generally include a mesh for filtering blood flowing within a blood vessel, particularly within an artery such as the aorta, a structure adapted to open and close the mesh within the blood vessel, a means to actuate the structure, and a balloon occluder which typically includes a flexible material enclosing a chamber. The methods generally include the steps of introducing a mesh into a blood vessel to capture embolic material, adjusting the mesh, if necessary, during the course of filtration, inflating the balloon occluder to occlude the vessel upstream of the mesh, and thereafter deflating the balloon occluder and removing the mesh and the captured foreign matter from the blood vessel. Additionally, visualization techniques are used to ensure effective filtration.
