ABSTRACT
We analyzed coupling expansion process of three different structures of stainless steel (SUS-316LI) stents by using finite element method (FEM) simulation in this study. Firstly we made specific analysis and comparison between three stents of deformation and stress-strain distribution in the coupling expansion process and then we described the shortening rate, radial bounce rate, expand nonuniformity, safety factor and other biological mechanics performance of the three stents quantitatively. And finally we analyzed the influencing factors and the best structure of the three kinds of the stainless steel stent comprehensively. Through all the processes, we have verified the rationality of the finite element simulation result by using the expansion test in vitro.
