Title:
METHOD FOR MANUFACTURING DRUG-ELUTING STENT COMPRISING THREE-DIMENSIONALLY-CONNECTED FLEXIBLE NANOSTRUCTURED FILM, AND DRUG-ELUTING STENT MANUFACTURED THEREBY
Document Type and Number:
WIPO Patent Application WO/2021/256743
Kind Code:
A1
Abstract:
The present invention provides a method for manufacturing a drug-eluting stent, in which a three-dimensional nanostructured film is formed on the surface of a stent, thereby enabling a drug to be coated thereon, and a drug-eluting stent manufactured thereby, and provides a method for manufacturing a drug-eluting stent and a drug-eluting stent manufactured thereby, the method comprising the steps of: (a) preparing a stent; (b) forming a three-dimensional nanostructured film on the surface of the stent; and (c) modifying the surface of the three-dimensional nanostructured film.
