Abstract
Coronary stent implantation has become an important method, of treating coronary heart disease. It has a pre-compression process when using the stent, which will be fixed in the balloon, and then be processing the expansion of operations. This research use the FE method, without considering the interaction of vessel stents and the circumstances under artery loading to simulate the three different materials (CoCr alloy, 316L stainless steel and Mg alloy), but it must has the same free pre-compression expansion process of the structure of the stent. By setting the mesh of the FE stent models, the boundary conditions, the loading, etc, and other key factors, The results demonstrate deformation mechanism, which can be used to calculate radical recoil rate and axial shortening rate. At last, the safety factors of stents are forecasted.
