Stent installation method using balloon catheter having stepped compliance curve

摘要: A method for installing a stent in vessel utilizes single balloon catheter both low pressure predilation at relatively small diameter to open the lesion sufficiently allow insertion and deployment of across subsequent high embedding wall. The same may also be employed insert deploy stent. balloons utilized have stepped compliance curve which allows predetermined substantially larger diameter. provided with configuration only portion has while further generally linear profile. With such treatment wall areas not reinforced by can avoided despite occurence longitudinal shrinkage during expansion thereof.
