[Hemodynamics analysis of intravascular stents with different design features].
Wall shear stress plays an important role in the development of in-stent restenosis. It has been demonstrated that low wall shear stress. is associated with neointimal hyperplasia. We used computational fluid dynamics (CFD) to investigate the steady and pulsatile flows in the vicinity of model stents and focused on the changes of wall shear stress caused by the implanted stents. The results showed that wall shear stress depended greatly on the size and structure of the stents, which would have implications for the optimization of intravascular
