Abstract: 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 translatable 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.

Abstract: 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.

Abstract: An example medical device for treating a body lumen is disclosed. The medical device includes an expandable scaffold including first and second regions, each of the first and second regions include a plurality of interstices located therein. The medical device also includes a covering spanning each of the plurality of interstices of the first region. The second region is free of the covering. A biodegradable gripping material is disposed on an outer surface of the covering. Further, the expandable scaffold is configured to shift from a collapsed state to an expanded state and the second region is configured to contact an inner surface of the body lumen in the expanded state. Additionally, the gripping material is designed to initially prevent migration of the expandable scaffold upon implantation in the body lumen until the second region is secured to the inner surface of the body lumen.

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: A braided stent having a plurality of retrieval and/or repositioning levers includes a stent body formed of a plurality of wires interbraided in a braided pattern. The repositioning and/or retrieval levers have a loop portion extending radially away from the stent body and first and second legs extending along the stent body. The levers are configured to be actuated radially inward toward the central longitudinal axis of the stent by a radially inwardly directed force to radially collapse the stent.

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.
