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 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 stent with a selectively covered end region. The stent includes a radially expandable tubular framework and a covering surrounding the tubular framework. The covering includes a skirt surrounding a distal end region of the tubular framework which is selectively removable from the distal end region of the tubular framework to expose the distal end region of the tubular framework to permit hyperplastic tissue ingrowth through the distal end region of the tubular framework. For example, the skirt may be folded, rolled, collapsed, or separated from the remainder of the covering to expose the distal end region of the tubular framework.
