Abstract：Abstract: To calculate the impact of working status of vessel wall with atherosclerotic and partial blockage of plaque formation. Base on the continuity equation of blood flow , the equation of motion and vessel wall equation of blood pressure .By given the wave function on the basis of blood pressure we can obtain a narrow blood vessel wall radial displacement and hoop stress and analysis of the different degree of stenosis of the vessel wall deformation and stress of . The force required to vascular stents of under different narrow circumstances and different levels of local plaque sclerosis and calculated the vessel wall after stent implantation of the radial displacement and stress state. The results of this study for clinical and correct stenting stent stenosis on the deformation and stress analysis of reference . Can avoid congested or hardening of blood vessels transition, due to stenting of inadequate medical vascular rupture.
