摘要： An occlusion device having a support structure and an expandable occlusion element associated with the support structure. The expandable occlusion element is formed of a self-expanding material, such as a hydrogel. A retainer may be provided to hold the expandable occlusion element with respect to the support structure of the occlusion device, within or outside the support structure, and positioned such that expansion of the expandable occlusion element occludes a lumen through the support structure and the occlusion device. Expansion of the expandable occlusion element may be reversible, or the expandable occlusion element may be releasable from the support structure.

摘要： An illustrative endoluminal implant having an elongated tubular member. The elongate tubular member having a proximal stent, a distal stent and an interconnecting sleeve. The proximal stent tapers from a first outer diameter adjacent the proximal end region to a second smaller outer diameter adjacent the distal end region. The distal stent has an outer diameter less than the first outer diameter of the proximal stent. The interconnecting sleeve is collapsible in response to an applied radial force such that the sleeve is positionable across a natural valve or sphincter.

摘要： An endoprosthesis includes an elongated tubular member including a filament forming circumferential rows having a plurality of knitted loops and intermediate rungs extending between adjacent knitted loops. The tubular member includes at least one window and may include a plurality of anti-migration loops adjacent the at least one window and configured to shift between first and second positions when unconstrained. Making the endoprosthesis includes forming the plurality of knitted loops and intermediate rungs in a first row of loops and rungs, extending the filament to form a second row of loops and rungs interwoven with the first row, and forming the at least one window without cutting the filament. Placing the endoprosthesis includes positioning the endoprosthesis within a body lumen adjacent a branch lumen, expanding the tubular member to span the branch lumen, and shifting at least some anti-migration loops toward the second position and into the branch lumen.

摘要： An implantable medical device includes an elongate body extending from a distal region to a proximal region, at least one of the distal region and the proximal region including a flared region defining an inner flared surface. One or more visual indicators are positioned relative to the inner flared surface such that the one or more visual indicators are visible endoscopically from a position within or proximate the implantable stent.

摘要： 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.

摘要： A stent with a selectively curved region. The stent includes a radially expandable tubular framework and a covering surrounding the tubular framework. A stent also includes a drawstring having a first end attached to the tubular framework at a first attachment location proximate the distal end of the tubular framework. The second end of the first drawstring is manipulatable proximate the proximal end of the tubular framework to deflect the tubular framework into a curved configuration.

摘要： A system for maintaining patency of a body lumen may include a first endoprosthesis configured to shift from a straightened configuration to a helical configuration defining a plurality of loops, and a second endoprosthesis configured to shift from a radially collapsed configuration toward a radially expanded configuration. The plurality of loops defines a passage having an inner diameter. At least a portion of the second endoprosthesis is disposed within the passage in the radially expanded configuration. A method of maintaining patency of a body lumen may include advancing a first endoprosthesis into a first body lumen in a straightened configuration, deploying the first endoprosthesis within the first body lumen in a helical configuration defining a plurality of loops, advancing a second endoprosthesis into the first body lumen in a radially collapsed configuration, and shifting the second endoprosthesis to a radially expanded configuration within the plurality of loops.

摘要： An endoprosthesis may include an expandable framework configured to shift between a delivery configuration and a deployed configuration, and a covering including a plurality of polymeric cover segments disposed about at least a portion of the expandable framework. A portion of each of the plurality of polymeric cover segments may be fixedly attached to the expandable framework. The plurality of polymeric cover segments is longitudinally spaced apart from each other in the delivery configuration. The plurality of polymeric cover segments longitudinally overlaps each other in the deployed configuration.
