A delivery system catheter that can track to a deployment location and has sufficient stiffness to support the catheter within the anatomy, thereby aiding with deployment of a stent with minimal movement of the stent. This results in more accurate placement of the stent at the deployment location. The delivery system catheter includes a catheter body having a proximal end, a distal end, and an interior wall surface defining a first lumen extending from the proximal end toward the distal end. A second lumen is disposed between the interior wall surface and an outer surface of the catheter body. A plurality of stiffening members is disposed around the second lumen, the plurality of stiffening members being engageable to selectively stiffen the catheter body.
