Due to the recent increase in the number of stent insertion procedures, the number of studies to evaluate the mechanical behaviors of stents, such as the stress and deformation states, using finite element analysis is also increasing. However, it is still not easy to design stents that are uniformly expanded and show enough radial strength and flexibility. Therefore, in this study, the Taguchi method and finite element analysis were used to determine a set of optimal design variables for unit patterns of stents, and a new design approach was developed to realize uniform expansion, enough radial strength and good flexibility. The stent designed using the new design approach was verified by experiments.
由于最近支架植入手术数量的增加，利用有限元分析来评估支架力学行为（如应力和变形状态）的研究数量也在增加。然而，设计出能均匀扩张并具有足够径向强度和柔韧性的支架仍然并非易事。因此，在本研究中，采用田口方法和有限元分析来确定支架单元图案的一组最优设计变量，并开发了一种新的设计方法以实现均匀扩张、足够的径向强度和良好的柔韧性。使用新设计方法设计的支架通过实验得到了验证。
