By introducing multiple second parts into the balloon catheter, which folds into a stable shape during both expansion and contraction, the problem of increased diameter of the balloon catheter during contraction after expansion is solved, thus improving the catheter's passability and stability.

AI Technical Summary
Existing balloon catheters have difficulty reducing their diameter during contraction after dilation, which may result in an increased diameter during withdrawal, affecting their permeability.
A catheter balloon is designed, comprising multiple first and second parts. The second part is adjacent to the central axis in the inflated state and moves toward the central axis before the first part during deformation to form a blade section, ensuring that the balloon always folds into a stable shape in both the inflated and contracted states.
This method achieves a stable reduction in balloon diameter during repeated deformation, improves intravascular permeability, and inhibits the expansion of the connection between the tip and base, ensuring catheter stability and permeability.
