METHOD FOR PREPARING DRUG-ELUTING STENT HAVING NANO-STRUCTURED PATTERN AND DRUG-ELUTING STENT PREPARED THEREFROM

摘要

This invention relates to a method for preparing a drug-eluting stent using a chemical vapor deposition, the method comprising modifying the surface of a biodegradable polymer with nanostructures through a plasma-assisted chemical vapor deposition so as to improve drug-loading capability and drug elution rate.
