Abstract: The present disclosure relates generally to the field of medical devices and establishing fluid communication between body lumens. In particular, the present disclosure relates to devices and methods for establishing a controlled flow or access passage between body lumens. For example, a device may include an elongate tubular body defining a lumen along a length thereof. The elongate tubular body may have an unexpanded configuration and an expanded configuration. In the expanded configuration, a proximal portion of the elongate tubular body may expand into a proximal retention member and a distal portion of the elongate tubular body may expand into a distal retention member, leaving a cylindrical saddle region extending therebetween. The cylindrical saddle region may include a constricted portion configured to move between a first diameter configuration and a second diameter configuration larger than the first diameter configuration.

Abstract: Medical devices and methods for using medical devices are disclosed. An example expandable medical device includes a tubular scaffold including an inner surface, an outer surface, a proximal end region, a distal end region, and a medial region extending between the proximal end region and the distal end region, wherein the tubular scaffold defines a folded-over portion, and wherein the folded-over portion extends from the distal end region toward the proximal end region. Further, the medical device includes a membrane disposed along the at least a portion of the medial region of the tubular scaffold.

Abstract: Medical devices and methods for using medical devices are disclosed. An example medical device includes a scaffold including an inner surface, an outer surface, a proximal end region, a distal end region, a lumen extending from the proximal end region to the distal end region, and a retention member extending radially away from the outer surface. The retention member has a distally facing surface and a proximally facing surface. A membrane is disposed within the lumen of the tubular scaffold and is secured to the inner surface of the tubular scaffold at a first circumferential attachment region and at a second circumferential attachment region. Further, the membrane is unattached to the inner surface of the tubular scaffold between the first circumferential attachment region and the second circumferential attachment region to define a tissue ingrowth region between the inner surface of the tubular scaffold and an outwardly-facing surface of the membrane.

Abstract: 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.

Abstract: 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.

Abstract: A knitted stent extending along a central longitudinal axis may comprise a filament forming a plurality of cells arranged in a plurality of columns and a plurality of rows. The plurality of rows may extend parallel to the central longitudinal axis. The plurality of columns may extend circumferentially around the central longitudinal axis. The plurality of rows may include a plurality of loop rows and a plurality of rung rows interposed between adjacent loop rows. Each cell within the plurality of loop rows may include a circumferential loop element connected to two longitudinally oriented connector elements. The plurality of rung rows may include a plurality of circumferential rung elements connected to adjacent loop rows. A majority of the plurality of loop rows may include open cells having an open end. At least one of the plurality of loop rows may include a plurality of closed cells having a closed end.

Abstract: A stent including a tubular body formed of one or more interwoven wires, a first anchor member disposed adjacent the first open end of the stent, a second anchor member disposed adjacent the second open end of the stent, and at least one divider disposed between the first and second anchor members. The first and second anchor members and the divider extend radially outward from the tubular body to divide the tubular body into at least a first saddle region extending between the first anchor member and the divider and a second saddle region extending between the second anchor member and the divider.

Abstract: 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.
