PURPOSE: A manufacturing method of a titanium nano-structure stent is provided to prevent vascular restenosis by suppressing the toxicity reaction of macrophage. CONSTITUTION: A manufacturing method of a titanium nano-structure stent comprises: a step of vaporizing titanium on the surface of a sample by using an electron-beam evaporator; and a step of forming a nano structure on the titanium surface by enhancing deposition speed. In the deposition step, the electron beam current density is 165-175 mA/cm^2. |
