Claim 8:
9. A method that treats lesions in a patient using balloon catheters, the method comprising:
for each lesion in a set of one or more primary lesions within a vessel lumen,
selecting a balloon catheter and configuration so that, when a balloon of the selected balloon catheter is inflated to a minimum therapeutic pressure sufficient to disrupt the lesion without damaging the vessel lumen, Pmin, which is less than a maximum useable internal pressure for the balloon, Pmax, and greater than an internal pressure at which the balloon unfolds and assumes an inflated shape, Pi, the length of the balloon does not exceed the length of the lesion;
centering the balloon of the selected balloon catheter within a portion of the vessel lumen containing the lesion;
raising the internal pressure of the balloon to Pmin;
evaluating any remaining secondary lesions; and
treating the remaining secondary lesions with selected balloon catheters and configurations with shorter inflated-balloon lengths and using internal balloon pressures greater than Pmin.
