Vascular stents involve materials science, mechanical design, biomedicine and other disciplines. It is multi-disciplinary high-tech integrated product. Vascular stent interventional therapy is an effective method to treat vascular stenosis diseases. With the rapid development of computers, finite element simulation is widely used in the design and development of vascular stents and its materials. Vascular stents prepared with degradable materials endow the stent with degradable characteristics, and also put forward higher requirements for materials and stent structure. This article introduced the relevant performance requirements of vascular stents and the development and application of finite element methods in stent research and development in details, providing a reference for the design and development of vascular stents.
