Thermomechanical analysis of shape memory polyurethane braided stent using finite element method
Polymeric stent is considered as an alternative of metallic stent which have some problems such as restenosis and short stenting period. Several elements need to be considered for designing an effective stent. Though, the biocompatibility of the stent may be the first issue for the stent procedure due to the restenosis, the mechanical behavior of a stent and stent-vessel interactions are also very important factors to ensure its opening within the arterial conduits. Since the technical success of a stent for many types of obstructive lesion depends directly on its mechanical behavior, a mechanical model is required to design the stent structure through predictive modeling. This study aimed to investigate the thermomechanical behaviors of polymeric braided stents that have thermal-induced shape memory properties and to analyze the effect of parameters for the optimal design.
