The Numerical Analysis on the Influence of Hemodynamic to Different Cross-sections of Struts
PENG Hongmei
Abstract：To provide the theoretical guidance for the optimal design of the stent to analyse the hemodynamic near the struts with the square,circle and oval cross -section.The blood flow fields,shear stresses on vessel wall and pressures on the struts were researched using the boundary element method after intervening three types of stents,which are square,circle and oval cross-section struts.Compared with the struts with the square or circle cross-section,the strut with the oval cross-section had certain advantages, which could reduce the blood flow disturbance,increased the stability of the stent,and avoided low speed vortex and low shear stress areas to be formed.The strut with the oval cross-section has certain advantages,which can increase the stability of the stent,and reduce restenosis.
