摘要： An endoprosthesis includes an expandable tubular framework having a first end, a second end, and a lumen extending therethrough along a longitudinal axis. The expandable tubular framework includes a plurality of interconnected struts. The interconnected struts include a radially outward face which includes a plurality of anti-migration grooves defining anti-migration teeth formed therebetween. The anti-migration teeth are configured to engage tissue to resist migration of the endoprosthesis within a body lumen.

摘要： An implantable stent (10, 10') includes a plurality of elongate wires (18) braided to form a hollow tubular structure having a tubular wall (16) to define an interior surface (106) and an,exterior surface (104) and having opposed open first and second ends (12.14), wherein the opposed open first and second ends (12, 14) are atraumatic ends The atraumatic ends of the stent are desirably free of any loose wire ends. The wires (18) include composite wires to enhance visibility of the wires to provide improved external imaging of the wires in the body. The elongate composite wires of the stent may be metallic wires having an outer metallic portion including a first metal, such as nitinol, and an inner metallic core portion including a second metal, which is a radiopaque material, such as gold, barium sulfate, ferritic particles, platinum, platinum-tungsten, palladium, platinum-iridium, rhodium, tantalum or combinations thereof.

摘要： The present invention relates to a stent delivery system (10), comprising a guide member (12) having a proximal portion and a distal portion; a stent (20) disposed about the distal portion of the guide member, wherein the stent has a wall having an opening ( 151) formed therein; a pusher member (14) disposed about the guide member (12) and positioned proximal of the stent (20); and a holding filament (44) with opposite ends extending to the proximal portion of the guide member (12) to form a loop extending through the opening of the stent; wherein the pusher member (14) has a tube wall having a proximal end and a distal end; wherein the pusher member (14) has lumens (354a, 354b) in the tube wall that extend between the proximal end and the distal end; and wherein a first portion of the holding filament (44) extends through one of the lumens (354a, 354b) and a second portion of the holding filament extends through another of the lumens (354a, 354b).

摘要： A handle for a medical device includes a distal portion extending longitudinally and including a distal channel extending therethrough, the distal end of the distal portion including a connector configured to connect to a proximal end of an endoscope, a central portion slidably connected to the distal portion, the central portion extending longitudinally. The handle also includes a central channel extending therethrough, the distal end of the central portion connected to a sheath, the central portion including an introducer port extending laterally therefrom so that an auxiliary tool inserted through the introducer port is directed through a lumen of the sheath. Further, the handle includes a proximal portion slidably connected to the central portion, the proximal portion extending longitudinally and including a proximal channel extending therethrough, the distal end of the proximal portion connected to a needle so that the needle is passed through the lumen.
