Abstract

In order to avoid the formation of low shear stress areas and improve the stent stability, in the current work, the boundary elementary method was applied to investigate the influence of strut structure on hemodynamic characteristics including the blood flow fields, shear stresses on a vessel wall and pressures on the struts. Results found that the struts with an oval cross section could lead to a homogenous pressure distribution and increased shear stress, which would lower the risk for restenosis after interventional therapy. Furthermore, such results would be beneficial to the structure design and optimization of stents used for the interventional therapy. Keywords: interventional therapy, strut structure, hemodynamic characteristics, the boundary element method.
