DRUG BALLOON BASED ON HYDROGEN-BOND INTERACTION AND COATING METHOD THEREFOR

摘要

Disclosed is a drug coated balloon based on hydrogen-bond interaction and the coating method therefor. The balloon comprises a balloon surface and a drug layer containing an active drug. The balloon surface carries hydrophilic groups as a result of treatment or modification; there is hydrogen-bond interaction between the balloon surface and the drug layer. The hydrogen-bond interaction increases the binding force between the drug layer and the balloon surface, thus ensuring the extensibility of the coated layer and favoring the loading of a drug on the balloon surface.
