摘要
利用液压方法测量国产钛镍形状记忆合金交叉网格血管内支架的力学性能的试验方法。并通过与平板压缩试验和包裹拉伸试验结果的比较 ,说明这是一种能近似模拟支架体内力学环境的自动测量方法 ,具有直观性好、可重复程度高等优点。
A test device is introduced which can give self-explanatory hoop strength by exertion of combined endovascular stent force and a hydraulic pressure on an elastic tube. Comparison with results from other test methods such as flat-plate compression and wrap-around collar test shows that this is a reliable and automatic approach to stent characterization in the physical biomechanical environment with a prospect for wide use in the development of homemade endovascular stent.
