An intravascular stent is a tubular structure intended for permanent implant in native or graft vasculature. The stent is designed to provide mechanical radial support after deployment. This support is meant to enhance vessel patency over the life of the device. In this work an approach for designing the geometry and construction of slotted-tube balloon-extendable stent, produced by Nd3+:YAG laser cutting from stainless steel 316L tube is proposed.
3D model of the stent, produced by ISMA Ltd, Sofia, is prepared by using SolidWorks. FEM analysis of the stent is performed and the mechanical properties are compared with variety of commercial stents.
