COATING METHOD FOR STENTS OR BIOMEDICAL IMPLANTS BY ELECTROSPRAY

摘要

PURPOSE: A coating method for stents or biomedical implants by electrospray is provided to make uniform surface coating possible and to allow various functionalities. CONSTITUTION: A coating method for stents or biomedical implants by electrospray is constituted as follows. The method of coating of the stent using electrospray or the transplantation water comprises the next step. A coating solution is supplied to an injection nozzle by applying pressure to the coating solution or pushing the coating solution at a constant speed. The coating solution is electrically charged by applying high voltage from a high voltage applying device to a metal material coming into contact with the coating solution. The surface of stents or biomedical implants is coated by spraying the charged coating solution.
