【Abstract】 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.更多还原
