    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: 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: 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.

    Abstract: 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.
