A low-profile steerable dilatation catheter for angioplasty procedures which has an inflated balloon on the distal end with little or no tendency to wrap on itself when the catheter is advanced through a patient's vascular system. The catheter comprises an elongated tubular member which is longitudinally relatively flexible but diametrically relatively rigid, a guide extension secured to the distal end of the elongated tubular member, and an inflatable balloon secured on the proximal end thereof to the distal end of the elongated tubular member and on the distal end directly or indirectly to the guide member or the tubular member and an elongated flexible member such as a helical coil secured to the guide extension distally of the balloon. The elongated tubular member is preferably a hypotube of stainless steel or nitinol.
