Claim 5:
6. A method that treats a lesion within a vessel lumen of a patient, the method comprising:
selecting a balloon catheter with a balloon of a length that does not exceed the length of the lesion when the balloon is inflated to a first treatment pressure;
preparing the patient to receive the balloon catheter;
centering the deflated balloon at the distal end of the balloon catheter within a portion of a vessel lumen containing the lesion;
raising the internal pressure of the balloon to Pan internal pressure at which the balloon unfolds and assumes an inflated shape, sufficiently slowly to avoid generating vessel-damaging forces during unfolding and/or initial inflation stages of the balloon;
raising the internal pressure of the balloon to the first treatment pressure of Pmin, a minimum therapeutic pressure sufficient to initiate disruption of the lesion without damaging the vessel lumen; and
removing remaining secondary lesions by selecting additional balloon catheters with shorter inflated balloon lengths and by using internal balloon pressures higher than Pmin.
