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.

Devices, systems, and methods for pyloric occlusion

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.

Stent and associated systems and methods

According to exemplary embodiments of the present disclosure, devices, systems, and methods for pyloric occlusion in an endoscopic procedure may include a first flange and a second flange connected to the first flange by a saddle region having a lumen. The second flange may be proximal to the first flange. The pyloric occlusion device may further include a closure element. The closure element may be configured to occlude a flow of material through the lumen, including across the pylorus when deployed. The closure element may be a closure of the lumen by rotation of one of the first or second flanges about the saddle region relative to the other of the first or second flange.

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.

Stent with selectively curved region

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.
