Claim 4:
5. The method of claim 4 wherein removing remaining secondary lesions by selecting additional balloon catheters with shorter inflated balloon lengths and by using internal pressures higher than Pmin further comprises:
reducing the internal pressure of the balloon to a pressure at or below P1 and removing the balloon catheter;
for each set of one or more remaining secondary lesions that can be treated in a next balloon-positioning-and-inflation cycle,
selecting a next balloon catheter with a next balloon length so that, when the internal pressure of a selected balloon with the next balloon length is subsequently raised to a next treatment pressure higher than the first treatment pressure, the length of the selected balloon will be either a minimum inflation length or, 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
raisin the internal pressure of the selected balloon to the next treatment pressure.
