ABSTRACT:
A method for coating bioactive material and a structured coated with a bioactive material are disclosed. The bioactive material coating method includes: flowing a coating solution, produced as a bioactive material is dissolved in a mixed solvent, inside a structure having a lumen; and coating the bioactive material on at least one of inner and outer surfaces of the structure, with different concentrations. The mixed solvent is mixed with two or more solvents having different features. The occurrence of the strangulation of blood vessels and inflammation can be reduced. An increase in the size of the myofibroblast is not suppressed. The coating solution is produced as a medication is dissolved in a mixed solvent, where the mixed solvent is produced as a polar solvent and a nonpolar solvent are mixed with each other at a certain ratio.
