Abstract: According to aspects of the present disclosure, a system may include a loading device including an exterior surface. The system may also include an expandable member mounted on the exterior surface of the loading device. The expandable member may be configured to selectively transition between a collapsed state and an expanded state. The system may also include a covering mounted on the expandable member. The covering may extend around the expandable member and the loading device. The loading device may be configured to position the expandable member and the covering for mounting on an exterior surface of an elongate introduction sheath.

Abstract: The present disclosure is directed to a valve structure that comprises a flexible structure having a distal portion configured for attachment to a first member and a proximal portion configured for attachment to a second member. The flexible structure is configured such that when the first member is extended distally relative to the second member, the flexible structure adopts a reduced width profile and such that when the first member is retracted proximally relative to the second member to a point of maximal retraction, the flexible structure adopts an expanded width profile, which is more resistant to deformation due to fluid pressure in a proximal direction than it is to deformation due to fluid pressure in a distal direction. The present disclosure is also directed to devices and methods pertaining to such a valve structure.

Abstract: A method for treating an intestine with an expandable scaffolding expanded within the intestine. After placing the expandable scaffolding at a target location, such as across a fistula, the first and second end portions of the expandable scaffolding are radially expanded such that the first and second end portions contact an inner surface of the intestine on opposing sides of the fistula, anchoring the first and second end portions to the intestine. Radially expanding the first and second end portions foreshortens the medial portion along the longitudinal axis such that the first and second end portions are drawn closer together along the longitudinal axis as the medial portion foreshortens to close the fistula.
