    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.

    Abstract: The present disclosure is related to medical devices, stents, occlusion devices, and the like, to occlude, limit, or otherwise facilitate a regulated fluid flow between body lumens. A medical device may be a pyloric occlusion device with first and second configurations. In the second configuration, the elongate body may comprise a first retention member, a second retention member, and a cylindrical saddle region configured to span a pyloric sphincter. The first retention member and the second retention member each include an inner wall, an outwardly circumferential wall, and an outer wall, a first interface connecting the inner wall and the outwardly circumferential wall, and a second interface connecting the outwardly circumferential wall and the outer wall. At least one of the outwardly circumferential wall or the interface of either the first retention member or the second retention member is configured to appose a pyloric antrum wall.

    Abstract: An occlusion device or plug having a proximal plug section and a distal plug section. The plug sections may each be shifted between an unexpanded configuration and an expanded configuration at the deployment site to occlude the deployment site. A tubular member such as a silicone tube may be used to form an occlusion device or plug shiftable or expandable into a desired configuration. An intermediate section between a proximal plug section and a distal plug section may be configured to be manipulated at least to shift at least one of the plug sections from an expanded configuration to an unexpanded configuration. A pair of stents may be coupled together via an intermediate section in such manner such that manipulation of the intermediate section causes at least one of the stents to shift from an expanded configuration to an unexpanded configuration.

    Abstract: Engageable stents disclosed herein may include an outer stent comprising an elongate body configured to be expandable between a constrained configuration and an unconstrained configuration. The elongate body in the unconstrained configuration may include a retention member and a cylindrical saddle region adjacent the retention member, the cylindrical saddle region defining a lumen extending along a longitudinal axis of the outer stent. The retention member of the outer stent may comprise a double-walled flange. The engageable stents may include an inner stent comprising an elongate body configured to be expandable between a constrained configuration and an unconstrained configuration. The elongate body in the unconstrained configuration may include a retention member and a cylindrical saddle region adjacent the retention member. The retention member of the inner stent may comprise a double-walled flange. The retention members of the outer and inner stent may be removably engageable with each other.

    Abstract: A mesh element having a mesh gauge selected to control flow of materials therethrough. The mesh element is implantable into an anatomical structure upstream of a body passage or within a body passage to control flow of materials through the body passage. The mesh element may be coupled to a support structure to facilitate anchoring of the mesh element in place relative to the body passage. The support structure may have a lumen defined therethrough to allow flow of materials through the body passage, with the mesh element regulating the flow of materials into the lumen. The mesh element alternatively may be directly coupled to an anatomical structure upstream of a body passage to regulate or determine flow of materials through the body passage.
