It is commonly known that the stent design has a significant influence on the flow topology and therefore on the wall shear stress (WSS) distribution as well.Postoperative complications like in-stent restenosis correlate with alterations in the WSS distribution.In the present computational fluid mechanic study the key design parameters of a generic model stent were investigated and the hemodynamical efficiency was evaluated by calculating the sensitivity.It can be concluded that the strut thickness is the most significant design parameter regarding the occurrence of low wall shear stress.
