METHOD OF SURFACE NANOCOATING FOR DRUG-ELUTING STENTS
摘要
PURPOSE: A nano coating method of the surface of a drug releasing stent is provided to control the surface of a drug releasing stent in a nanometer scale. CONSTITUTION: A nano coating method of the surface of a drug releasing stent is constituted as follows. The surface of a stent is coated by spraying bio-degradable high molecule solvent containing biodegradable polymer on the surface of the stent by using an ultrasonic wave spray machine. The average drop size of the bio-degradable high molecule solvent is controlled in a size of 10-100 micrometers.
