METHOD FOR MANUFACTURING COATED STENT OF DRUG RELEASE CONTROLLING TYPE USING BIOCOMPATIBLE POLYMER

摘要

PURPOSE: A method for manufacturing a drug release controlling type stent using a biocompatible polymer for coronary stenting is provided to control a drug release period and to lower a restenosis rate after performing a coronary stenting operation. CONSTITUTION: The manufacture method comprises: washing stent to remove foreign matter attached on the surface of the stent; immobilizing biomolecules through a covalent bond of stent polysulfone; synthesizing polysulfone having isocyanate attached thereto and attaching a carboxyl group to the synthesized polysulfone; producing morpholinoethanesufone; and mixing the stent with adipic acid in a PH 3-6 MES buffer solution.
