摘要

在支架内表面添加微结构可以降低阻力，抑制血液粘附现象。本研究以仿生学为基础，提出了鱼鳞状微结构血管支架的设计方案，并利用有限元法对其主要设计参数进行了优化。此外，还比较分析了标准支架和鱼鳞状微结构支架对理想脑动脉瘤的血流动力学效应。结果表明，与标准支架相比，鱼鳞状微结构支架明显加快了 11.6% 的腔内血流速度。此外，鱼鳞状微结构支架还能将进入动脉瘤腔内的血流量减少 28.6%。

Design of fish-scale microstructured stents and their biomechanical effects on cerebral aneurysm.

The addition of microstructures to the inner surface of the stent reduces resistance and inhibits the phenomenon of blood adhesion. In this study, the design of a fish-scale microstructured vascular stent was proposed based on bionics, and its main design parameters were optimized using the finite element method. In addition, the hemodynamic effects of a standard stent and a fish-scale microstructured stent on an ideal cerebral aneurysm were comparatively analyzed. The results showed that the fish-scale microstructured stent significantly accelerated intraluminal blood flow velocity by 11.6% compared to the standard stent. In addition, the fish-scale microstructured stent was able to reduce blood flow into the aneurysm lumen by 28.6%.
