Structural design of patient-specific vascular ring stents

Abstract The expediency of replacing the corrugated ring a vascular stent with constant corrugation pitch by variable is being investigated. To describe change in corrugation, special function introduced. equilibrium and deformation equations were analyzed using asymptotic homogenization method. dependence radial stiffness on constructive parameters obtained. effectiveness design under consideration evaluated area lumen provided stent. Compared to stents regularly rings, this larger which improves efficiency.
