To provide a reference basis for the structural design and optimization of endovascular stent by analyzing the flow resistance of the new stent with triangle cross-section using numerical simulation method, and finding out the stent structure which will influence hemodynamic parameters. Four kinds of models of the triangle cross-section bare stent were constructed in infinite flow field using solidworks software. Numerical simulations of the four models were performed respectively using ANSYS finite element software. Steady flows and transient flows in these models were studied. Hemodynamics data in the four models were collected, such as the flow patterns, the distribution of pressure and the flow resistance of the new stents. The stent with triangular wire cross-section can be applied to cover aneurysm cavity because that resistance of blood inflow to aneurysm was large and outflow from aneurysm was small. Thus, it was easy to outflow than inflow. Thereby blood perfusion and flow of aneurysm cavity was restrained, and the pressure of aneurysm cavity was reduced, which plays a certain effect on the treatment of aneurysm. This result provides some instructions for the design of stent structure.
