Abstract: A medical stent includes an elongate tubular body extending from a proximal end region to a distal end region. The distal end region of the elongate tubular body may be adapted to resist migration as a result of peristaltic force. The distal end region of the elongate tubular body may include two or more longitudinally-extending voids and two or more longitudinally-extending dynamic engagement features that are defined between adjacent longitudinally-extending voids. The two or more longitudinally-extending dynamic engagement features are adapted to splay radially outwardly in response to an applied peristaltic force, thereby dissipating the applied peristaltic force.

Abstract: A stent includes a tubular body formed of one or more interwoven wires, the tubular body having first and second opposing open ends and a lumen extending therebetween. The stent further includes a first anchor member disposed adjacent the first open end and a second anchor member disposed adjacent the second open end, the first and second anchor members each extending radially outward from the tubular body, the first and second anchor members each having an outer diameter larger than an outer diameter of the tubular body disposed between the first and second anchor members. A plurality of spacer members are disposed around the first open end and extending longitudinally beyond the first open end, wherein when a pulling force is applied to the spacer members, the outer diameter of the tubular body is not reduced.

Abstract: An endoprosthesis may include an expandable framework configured to shift between a delivery configuration and a deployed configuration, and a covering including a plurality of polymeric cover segments disposed about at least a portion of the expandable framework. A portion of each of the plurality of polymeric cover segments may be fixedly attached to the expandable framework. The plurality of polymeric cover segments is longitudinally spaced apart from each other in the delivery configuration. The plurality of polymeric cover segments longitudinally overlaps each other in the deployed configuration.

Abstract: An implantable stent may include a braided tubular member formed of braided wires and including radially outward wire segments crossing over and positioned radially outward of radially inward wire segments at a plurality of crossover points. Also, the radially outward wire segments may be coated with a coating and the radially inward wire segments may be uncoated and devoid of the coating.

Abstract: A system for treating a body lumen including a first stent configured to be positioned in a body lumen and a second stent configured to be positioned in the lumen of the first stent prior to removing the first stent from the body lumen. The first stent includes a liner disposed radially inward of the tubular scaffold of the first stent to permit tissue ingrowth within a tissue ingrowth region defined between the liner and the tubular scaffold. The retrieval stent is configured to be expanded within the previously implanted first stent to cause tissue to recede from the tissue ingrowth region to facilitate removal of the first stent from the body lumen.

Abstract: Stent delivery device including an inner member having a distal tip, a stent support member, and a stent disposed over a stent receiving region of the stent support member. An elongated outer sheath is slidably disposed over the inner member and the stent. The stent delivery device includes a distal junction removably coupling the distal end of the outer sheath to the distal tip, where the distal junction is actuatable to decouple the outer sheath from the distal tip. The stent delivery device includes a proximal junction removably coupling a distal portion of the outer sheath to a proximal portion of the outer sheath, where the proximal junction is actuatable to decouple the distal portion of the outer sheath from the proximal portion of the outer sheath. The distal and proximal junctions may be separately actuatable by rotating the inner member relative to the proximal portion of the outer sheath.

Abstract: Example medical stents are disclosed. An example stent includes a tubular framework including an inner surface, an outer surface and a lumen extending therethrough. Additionally, the stent includes a tissue ingrowth scaffold extending along a portion of the outer surface of the tubular framework, wherein the tissue ingrowth scaffold is spaced radially away from the outer surface of the tubular framework to define an expansion cavity therebetween and wherein the tissue ingrowth scaffold permits tissue ingrowth along a portion thereof. Further, the stent includes an expandable member positioned within at least a portion of the expansion cavity.

Abstract: An illustrative endoluminal implant having an elongated tubular member. The elongate tubular member having a proximal stent, a distal stent and an interconnecting sleeve. The proximal stent tapers from a first outer diameter adjacent the proximal end region to a second smaller outer diameter adjacent the distal end region. The distal stent has an outer diameter less than the first outer diameter of the proximal stent. The interconnecting sleeve is collapsible in response to an applied radial force such that the sleeve is positionable across a natural valve or sphincter.
