The present invention relates to a stent coating apparatus and a coating method using the same and, more specifically, to a stent coating apparatus which comprises: a holding tool which moves back and forth in the longitudinal direction of the stent while holding and rotating the dried stent which will be coated; a spray tool which includes a spray nozzle and sprays the stent, which is moved forward and backward when rotated by the holding tool, with a coating solution; and a dry tool which coats by drying the coating solution coated by the spray tool. In the holding tool: a plurality of coating solution bubbles are formed on the stent by being sprayed with the coating solution by the spray tool in a process which moves the stent back and forth for several times; a predetermined amount of coating solution bubbles are continuously formed on non-coated stent; and the coating solution bubbles are immidiately dried in order to coat the stent in a desired thickness. The plurality of coating solution bubbles are immidiately dried by the dry tool in order to prevent the coating solution bubbles from being spread over the adjacent area. According to the the present invention, the stent coating apparatus uniformly sprays the coating solution on whole stent by rotating the stent and moving back and forth and coats the stent with uniform thickness and amount of the coating solution by drying the coated coating solution in short time so that product quality can be enhanced. |
