a mandrel body including:
a first stent shaping segment having a first diameter, a second stent shaping segment having a second diameter different from the first diameter, and a tapered segment disposed between the first and second stent shaping segments, the tapered segment defining a tapered surface that angles from the first stent shaping segment to the second stent shaping segment;
a main bore extending within the mandrel body along a longitudinal axis of the mandrel body; and
a plurality of apertures extending through the tapered surface of the mandrel body and radially disposed about the longitudinal axis of the mandrel body, the plurality of apertures extending directly into the main bore;

a plurality of movable pins radially disposed about the longitudinal axis and outwardly extendable from the plurality of apertures; and
an actuation element engageable with the main bore extending within the mandrel body and including a tapered surface configured to engage the plurality of movable pins, the actuation element being actuatable relative to the mandrel body along the longitudinal axis of the mandrel body such that the tapered surface supports the plurality of movable pins extended from the plurality of apertures to form an anti-migratory stent, wherein each of the plurality of movable pins is configured to extend from one of the plurality of apertures at an acute angle relative to the longitudinal axis of the mandrel body.
