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.

Abstract: 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.

Abstract: The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to medical devices for facilitating the flow of fluids and materials in and/or between adjacent body lumens, for example, a stent which maintains an open flow passage between body lumens. In one example, a stent may have a constrained configuration and an expanded configuration. In the expanded configuration, the stent may have first and second retention members and saddle region extending therebetween. The saddle region may comprise a coil configured to apply a restoring force to tissue surfaces respectively apposed to the first and second retention members.

Abstract: The present disclosure relates generally to the field of medical devices and medical device delivery. In particular, the present disclosure relates to medical devices and delivery systems for positioning and delivering medical devices with an unsupported structure, for example, within a distant and/or tortuous portion of body lumen. For example, a delivery system may position a supported structure of a medical device within a proximal portion of a body lumen and an unsupported structure of the medical device within a distal portion of the body lumen. Examples include delivery systems within an unsupported structure of a medical device to be delivered, wherein a number of balloons are arranged un-inflated within the unsupported, with a distal balloon removably attached to a distal portion of the unsupported structure, and the balloons are inflatable in series to deploy the unsupported structure linearly from the distal end of the delivery system.
