Laser cutting error has large influence on the beam width of intravascular stents. Minor
random variation in beam width of stents may significantly impact the expansion uniformity. In this
paper, the relevant factors that may affect the beam width during the manufacture are investigated.
Based on the randomization model, the pattern how the factors affect expansion uniformity is
explored, and the method for calculating uniformity index is proposed. A detailed computation is
made on the width randomization for the two expansion elements. The results show that with the
increase of the value range of beam width, probability of uniformity index decreases gradually; the
strengthening factor has large effect on the expansion uniformity. The method is meaningful for
studying how the processing error affects expansion uniformity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
