摘要： 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.

摘要： A mandrel for forming a stent with a tapered profile and one or more anti-migration features includes a first stent shaping segment having a first diameter, a second stent shaping segment having a second diameter less than the first diameter and a tapered segment disposed therebetween. A third stent shaping segment is releasably securable to the second stent shaping segment and has a third diameter greater than the second diameter. One or more movable pins are outwardly extendable from corresponding apertures formed within the tapered segment. An actuation element is engagable with the first stent shaping segment and includes a tapered surface configured to engage the one or more movable pins and support the one or more movable pins extended from the corresponding apertures.

摘要： 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.

摘要： An occlusion device including a first component configured to anchor the occlusion device with respect to a deployment site, and a second component configured to occlude a lumen through the occlusion device. The first component may be in the form of a stent. The second component may be in the form of a stent or in the form of a liner within the first component. The second component includes an occlusion structure configured to extend across (e.g., transverse to the longitudinal axis of) the lumen of the first component. The occlusion structure may be on a retention member of the second component which engages with a retention member of the first component. Additionally or alternatively, the occlusion structure may be a portion of a liner cinched to occlude the lumen through the occlusion device.

摘要： The present disclosure relates generally to stents, systems, and methods for gastrointestinal treatment. In some embodiments, a stent may include a tubular scaffold having a first end opposite a second end, wherein a lumen extends between the first and second ends. The tubular scaffold may include a flared section and a medial section extending from the flared section, wherein a first diameter of the flared section is greater than a second diameter of the medial section. The stent may further include a liner extending partially along a surface of the tubular scaffold, wherein the liner is spaced from an anchoring region of the flared section to promote tissue ingrowth with the flared section.

摘要： An example medical device is disclosed as an expandable stent. The stent includes a tubular scaffold having an inner surface, an outer surface, and a lumen extending therein. The expandable stent also includes a liner disposed within the lumen of the tubular scaffold. Further, the liner is radially spaced from a medial region of the tubular scaffold to define a tissue ingrowth region along an uncovered portion of the medial region. Additionally, the liner extending along the tissue ingrowth region is configured to limit the amount of tissue ingrowth along the medial region of the scaffold.

摘要： Medical devices and methods are disclosed in the present application. In one illustrative example a tissue removal device may comprise an elongate shaft defining a lumen and having a proximal end and a distal end, wherein a proximal portion of the elongate shaft has a first diameter and a distal portion of the elongate shaft has a second diameter, and wherein the first diameter is less than the second diameter and an elongate member disposed at least partially within the elongate shaft, the elongate member having a proximal end and a distal end, the distal end of the elongate member comprising a cap. In some further embodiments, the elongate member may be axially translateable between a proximal position and a distal position, and the cap may form a closed receptacle with the distal portion of the elongate shaft when the elongate member is in the proximal position.

摘要： The present disclosure relates generally to stents, systems, and methods for anchoring devices within a body lumen by cooperation between the device and the body musculature. A device comprising an elongate tubular member may be deployed within a body lumen, where the body lumen includes a sphincter that regulates flow through the body lumen. The elongate tubular member includes a sleeve formed from a flexible membrane and one or more stents disposed at either or both ends of the sleeve. In some embodiments, the stents may be treatment stents configured to treat a portion of the body lumen. The elongate tubular member may be deployed within the body lumen such that the flexible membrane aligns with and moves in coordination with the sphincter, thereby increasing retention forces acting upon the elongate tubular member when the sphincter is closed to minimize treatment stent migration.
