PROBLEM TO BE SOLVED: To provide a balloon coating method capable of coating while the thickness of a coating layer, pharmaceutical morphological types, etc. are being freely adjusted depending on balloon sites.SOLUTION: The provided method includes an immersion step of inserting a balloon 30 into a tubular member 160 capable of storing a coating solution R including a volatile solvent into which a water-insoluble pharmaceutical has been dissolved and then feeding the coating solution R into the gap between the outer surface of the balloon and the inner wall surface of the tubular member, a draw-up step of drawing up the balloon 30 from the tubular member 160 by mobilizing the balloon 30 along the axial direction thereof, and a volatilization step of volatilizing the volatile solvent of the coating solution R adhered to the outer surface of the balloon 30.COPYRIGHT: (C)2015,JPO&INPIT【課題】コーティング層の厚さや薬剤の形態型などを、バルーンの部位に応じて自在に調節しつつコーティング可能なバルーンコーティング方法を提供する。【解決手段】水不溶性薬剤を溶解させた揮発性溶媒を含むコーティング液Rを収容可能な管状部材に前記バルーンを挿入し、前記バルーン30の外表面と前記管状部材160の内壁面の間の隙間に前記コーティング液Rを供給する浸漬工程と、前記バルーン30を当該のバルーン30の軸方向へ移動させて前記管状部材160から引き上げる引き上げ工程と、前記バルーン30の外表面に付着した前記コーティング液Rの揮発性溶媒を揮発させる揮発工程と、を有している。【選択図】図9
