Abstract: A balloon catheter retractor (1), comprising a balloon catheter (13) and a balloon (12) fixed on the balloon catheter (13), wherein when the balloon (12) is inflated with a fluid, the balloon (12) bends and drives the balloon catheter (13) to bend correspondingly. By applying a radial limit to the balloon (12), the balloon (12) does not expand in a diametrical direction when expanding to a certain diameter. The balloon catheter retractor (1) can enhance the bending capacity and the characteristic of maintaining the bending performance.
