Claim 3:
4. The method of claim 1 wherein removing remaining secondary lesions by reconfiguring the balloon catheter to produce shorter inflated balloon length and internal pressures higher than Pmin further comprises:
reducing the internal pressure of the selected balloon to a pressure at or below Pi;
for each set of one or more remaining secondary lesions that can be treated in a next balloon-positioning-and-inflation cycle,
adjusting the length of the selected balloon, while maintaining the internal balloon pressure below Pi, so that, when the internal pressure of the selected balloon is subsequently raised to a next treatment pressure higher than the first treatment pressure, the length of the selected balloon will be greater than a minimum inflation length but, when possible, less than or equal to the length of the set of one or more remaining secondary lesions;
centering the selected balloon within a portion of a vessel lumen containing the set of one or more remaining secondary lesions; and
raising the internal pressure of the selected balloon to the next treatment pressure.
