Abstract The mechanical behaviors during crimping and expansion as well as the flexibility of coronary stent made of nickel-free stainless steel were simulated in this paper. The longitudinal recoil, radial recoil and the deformation behavior in crimping and expansion for different stent mesh width were investigated. The moment-deflection curve and flexibility of the stent were calculated. The results show that the nickel-free stainless steel stent has smaller longitudinal and radial recoil, and excellent flexibility in elastic bending deformation process.
