Method for manufacturing of drug-releasing stent coated with titanium—oxide thin film |
摘要 |
A method for manufacturing a drug-releasing stent is provided. The method includes providing a titanium precursor, a carrier gas and a reactant gas in a plasma vacuum chamber, and generating a plasma for 1 to 6 hours to form a titanium oxide thin film on the surface of a stent. The method further includes providing steam or oxygen and hydrogen in the plasma vacuum chamber and generating a low-temperature plasma for 10 minutes to 2 hours to modify the surface of the titanium oxide thin film. The method further includes reacting the titanium oxide thin film of the stent with a drug in an acidic solution and under an inert gas atmosphere at room temperature to 100° C. for 30 minutes to 4 hours to attach the drug. |
