A method of manufacturing a covered stent is disclosed. The method includes winding a first PTFE tape around a cylinder body of a jig, winding a second PTFE tape around a stent including the jig fitted therein, heating the stent in an oven, fitting the stent into upper and lower elastic members, fitting the elastic members into a mold, pressing the upper elastic member to bond the PTFE tapes to each other and to thus form a first film at a cylindrical body of the stent, taking the elastic members out of the mold, taking the stent out of the elastic members, removing the jig from the stent, forming a silicone coating layer at an expansion portion of the stent, and sewing the spaces in the expansion portion, the second PTFE tape, and the silicone coating layer to form a second film at the expansion portion. |
