Zusammenfassung:	The utility model provides a balloon catheter which comprises a balloon which comprises a balloon main body portion and has a compression state and an expansion state. The balloon restraining assembly comprises at least one restraining rod, the restraining rod is spirally wound on at least part of the outer surface of the balloon main body part to form a spiral structure, and the spiral structure extends in the axial direction of the balloon; and when the balloon is in an expanded state, at least part of the restraint rods are arranged to radially limit at least part of the balloon main body part. The spiral structure is formed on the outer side of the balloon main body part through the restraining rod, compared with other restraining structures, the spiral structure has better back-holding performance, meanwhile, the spiral structure extends and winds in the axial direction of the balloon, restraining force in different directions can be applied to the balloon, and axial expansion of the balloon is more suff
