The catheter assembly includes a main catheter branch, a side catheter branch arrangement, and a stent. The main catheter branch includes at least a main balloon and a side balloon. The side catheter branch arrangement includes a branch guidewire housing and a sleeve member. At least a portion of the side catheter branch arrangement extends through a proximal open end of the stent and out through a side branch aperture of the stent. The branch guidewire housing defines a side branch lumen configured to advance over a branch vessel guidewire. The sleeve member is sized to receive the branch guidewire housing, wherein the branch guidewire housing is axially movable within the sleeve member. The sleeve member is typically fixed axially relative to the main catheter branch.
