Methods, apparatuses, and systems are described for stent delivery and positioning for transluminal application. The method may include positioning the stent in an undeployed configuration through an access site in a wall of a first body lumen. In some cases, the method may include retracting an outer sheath proximally and past an anchoring component disposed at a distal portion of an inner tubular member based on positioning the stent. A distal portion of the stent may be disposed between the anchoring component and the outer sheath while the stent is in the undeployed configuration. The method may further include deploying the distal portion of the stent from the outer sheath and within the first body lumen and expanding a proximal portion of the stent from within the outer sheath such that upon fully exiting the outer sheath, the proximal portion expands to a deployed configuration within a second body lumen.

Apparatuses, and systems are described for stent designs for transluminal application. The stent may include a stent body having a diameter and a length in a deployed configuration. The stent may include a helical wrapping pattern that is at least partially covered with a material. The helical wrapping pattern may be configured to reduce a foreshortening of the stent body upon deployment from an undeployed configuration to the deployed configuration to less than ten percent of a length of the stent body in the undeployed configuration. In some cases, the stent may include a first anchoring member coupled with a distal portion of the stent body and a second anchoring member coupled with a proximal portion of the stent body. The first and second anchoring members may be configured to increase a diameter of the stent.

The present disclosure relates to a gastrointestinal delivery device of a dressing, where the delivery device is capable of fitting through a narrow channel before expanding and applying the dressing. The gastrointestinal delivery device may be used in all gastrointestinal bleeding applications and can be used with a biocompatible, foldable, thin profile, chitosan dressing. Various aspects of the device and its uses are provided herein.

An esophageal stent configured to span a stricture may include a tubular body configured to shift between a delivery configuration and a deployed configuration, the tubular body having a first end and a second end. In the deployed configuration: the tubular body defines a first flange portion, a second flange portion, and a saddle portion extending from the first flange portion to the second flange portion; the tubular body further defining an overall longitudinal length extending from the first end to the second end; the first flange portion has a first outer radial extent, and the second flange portion has a second outer radial extent; the first outer radial extent and the second outer radial extent are greater than an outer radial extent of the saddle portion; and a longitudinal length of the saddle portion is at least 50% of the overall longitudinal length of the tubular body.
