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.

Flow control stent

A mandrel for forming a stent with a tapered profile and one or more anti-migration features includes a first stent shaping segment having a first diameter, a second stent shaping segment having a second diameter less than the first diameter and a tapered segment disposed therebetween. A third stent shaping segment is releasably securable to the second stent shaping segment and has a third diameter greater than the second diameter. One or more movable pins are outwardly extendable from corresponding apertures formed within the tapered segment. An actuation element is engagable with the first stent shaping segment and includes a tapered surface configured to engage the one or more movable pins and support the one or more movable pins extended from the corresponding apertures.

Adjustable mandrel for forming stent with anti-migration features

The present disclosure relates generally to the field of stents for body lumen drainage. In particular, the present disclosure relates to systems and methods for forming a fluid channel between tissue walls of varying thickness using a stent.
