PROBLEM TO BE SOLVED: To solve the problem in which insertion of a rod-shaped core material into the balloon catheter distal end may fail if the center of a protective tube and the center of the guide wire lumen distal end of the balloon catheter are not matched with each other, when inserting the rod-shaped core material into the balloon catheter with the protective tube covered on the inner tube balloon of the object having a structure in which the distal end of the inner tube is inside the outer tube with a double tube structure.SOLUTION: Provided is a method for manufacturing a balloon catheter with a rod-shaped core material inserted into a guide wire lumen, in which a balloon is covered with a protective tube and a rod-shaped core material is inserted into a guide wire lumen, in which the distal end of the balloon catheter is brought into contact with the inner wall of the protective tube by pushing the distal part of the protective tube against the base, and the rod-shaped core material is inserted into the guide wire lumen in the contacted state.SELECTED DRAWING: Figure 2dCOPYRIGHT: (C)2020,JPO&INPIT【課題】 二重管構造で内管の遠位端は外管の内側にあるような構造の対象物の内管バルーンに保護管が被さったバルーンカテーテルに棒状芯材を挿入する際、バルーンカテーテルのガイドワイヤールーメン遠位端のセンターと保護管のセンターが一致しない場合、棒状芯材をバルーンカテーテル遠位端への挿入が失敗する可能性がある。【解決手段】 バルーンに保護管が被せられ、棒状芯材がガイドワイヤールーメンに挿入されたバルーンカテーテルの製造方法であって、保護管の遠位部を台に押し付けることによって、バルーンカテーテルの遠位端を保護管の内壁に接触させ、接触させた状態で棒状芯材をガイドワイヤールーメンに挿入する、棒状芯材がガイドワイヤールーメンに挿入されたバルーンカテーテルの製造方法。【選択図】 図２ｄ
