Abstract:Vascular stent is an important kind of medical device for the treatment of the vessel occlusion. In this work, we designed and fabricated a kind of biodegradable vascular stent. The dynamics of expanding, compressing and bending process for the single "sine", "60 degrees sine" and "U" type stent unites were analyzed with Finite Element Method (FEA) respectively, and furthermore, the expanding characters of polylactic acid (PLA) stent models with length of 4mm, 6mm, and 8mm were simulated. The "sine" type brack… Show more
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.
