An adaptor for use with balloons of intravascular balloon catheters commonly used for treating conditions of the vascular system includes a hollow member and an elongated positioning member, which is connected to the hollow member. The hollow member possesses characteristics not possessed by the balloon of the balloon catheter. With a balloon catheter positioned within a blood vessel, the adaptor is capable of longitudinal movement through the blood vessel, between the balloon catheter and a wall of the blood vessel, independent of the balloon catheter. The adaptor is manuevered adjacent to the balloon by manipulating the positioning member until a proximal end and a distal end of the adaptor is generally aligned with a proximal and distal end of the balloon, respectively. Inflation of the balloon secures the hollow member against the balloon in such a manner that the characteristics of the hollow member are imparted to the balloon.
