1. A method for delivering a stent from a first body lumen to a second body lumen through apposed walls of said lumens, said method comprising:

  • positioning an endoscope in the first body lumen adjacent to a target site on the wall of the first body lumen, which is a luminal wall;

    advancing a catheter assembly in a working channel of the endoscope to locate a distal region of the catheter assembly at the target site;

    advancing a portion of the catheter assembly through a hole in the apposed walls at the target site, the catheter assembly including a stent deployment sub-assembly;

    expanding a distal flange on the stent in the second body lumen by retracting a sheath;

    stopping the retraction of the sheath at a pre-determined distance that is less than a length of the stent;

    drawing proximally on the stent deployment sub-assembly to pull the distal flange against the wall of the second body lumen to maintain the walls in apposition; and

    after drawing proximally, expanding a proximal flange on the stent in the first body lumen to complete delivery by further retracting the sheath.
