A vascular catheter includes a flexible catheter body having proximal and distal ends and an elongate housing secured to the distal end of the catheter body. An interactional device is disposed on one side of the housing, and at least two spaced-apart inflatable chambers are located on the other side of the housing generally at its proximal and distal ends, respectively. The inflatable chambers may be expanded simultaneously or separately, and the spaced-apart positioning of the chambers provides for stable positioning of the housing during atherectomy procedures, imaging procedures, and the like. The balloon is conveniently connected to the housing by an integral flange structure which is secured through an inflation aperture on the housing side. The balloon may be inflated through an annular inflation which is defined by a separate isolation tube disposed in the central lumen of the catheter body.
