The retrieval suture including a first suture loop extending about a circumference of the stent and adjacent to a suture retrieval loop and a second suture loop extending about a circumference of the stent and longitudinally spaced from the first suture loop. The first and second suture loops coupled via one or more interconnecting segments. At least one of the first or second suture loops has an arc length of less than 270° of the circumference of the stent.

Repositionable and removable stents

An esophageal stent configured to span a stricture may include a tubular body configured to shift between a delivery configuration and a deployed configuration, the tubular body having a first end and a second end. In the deployed configuration: the tubular body defines a first flange portion, a second flange portion, and a saddle portion extending from the first flange portion to the second flange portion; the tubular body further defining an overall longitudinal length extending from the first end to the second end; the first flange portion has a first outer radial extent, and the second flange portion has a second outer radial extent; the first outer radial extent and the second outer radial extent are greater than an outer radial extent of the saddle portion; and a longitudinal length of the saddle portion is at least 50% of the overall longitudinal length of the tubular body.

Stent with improved anti-migration properties

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.

System, device and method for anchoring a stent

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.
