Abstract: The present invention relates to a device for coating the inside of an artificial blood vessel and, to explain more specifically, to a device for coating the inside of an artificial blood vessel inserted into the body of a human for a medical purpose, which is configured to be able to selectively coat just the inside of a lumen of the artificial blood vessel with a bioactive substance for inhibiting neointimal hyperplasia, in order to prevent a side effect, such as angiostenosis or inflammation, from occurring in an area connecting the artificial blood vessel and a blood vessel in the body.

Abstract: A method for coating medication for a medical product is disclosed. A technique for coating gel in a viscous semisolid state is provided to facilitate coating of medication. Coating of medication on an article can be facilitated using gel, and coating of medication on an article such as an article made of silk and an article made of polypropylene can be further facilitated.

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.
