通过对微盲孔支架管材和电抛光支架管材的拉伸对比实验及微盲孔支架和电抛光支架径向支撑力学性能的对比实验研究,测试结果显示微盲孔处理前后性能偏差很小,表明支架表面微盲孔结构基本不会影响支架的力学性能,证实了微盲孔支架的安全性,利于微盲孔支架的推广使用。
Through comparative tensile experiments of two kinds of stent tubes with micropores and electro polished and comparative radial strength experiments of two kinds of stents with micropores and electro polished,the results show that the deviation of mechanical properties of stent with micropores is very small in comparison with stent without micropores.This indicates that micropores structure on the stent surface almost does not have any effect on the mechanical performance of stent and proves that the stent with micropores is safe,which may help to promote the use of polymer-free stent direct drug-loading by micropores.
