1. A stent, comprising:
a first flange having a first surface configured to face a region of the anatomy that is tissue forming a stricture;
a second flange configured to transition between an inflated state and a deflated state, the second flange having a second surface configured to face the region of the anatomy, wherein:
in the deflated state, the second flange is further configured to allow for passage of the second flange through the stricture, wherein an outer diameter of the second flange is smaller than an outer diameter of the first flange in the deflated state, and
in the inflated state, the second flange is configured to longitudinally compress the strictured tissue in the inflated state;
a shaft connecting the first surface of the first flange and the second surface of the second flange; and
an actuator mechanism on the first flange or the second flange, the actuator mechanism configured to apply force such that the first flange and the second flange at the inflated state are drawn together to longitudinally compress strictured tissue.
