Abstract: A balloon pulling device, comprising a core tube (11) portion and a balloon (12) portion, wherein the core tube (11) portion may inflate and deflate the balloon (12) portion by using a fluid; the present invention is characterized in that the balloon (12) portion comprises a plurality of expansion segments (13), the expansion segments (13) being larger than the remaining portion of the balloon (12) after being inflated with a fluid such that the entire balloon (12) forms a curved contour. A simple and reliable balloon pulling device capable of retracting at a long distance while being finely adjusted is achieved.

Abstract: Provided is a traction device for curved balloon catheter, which is characterized by comprising: a catheter (5) with a handle (2) at one end, a locator (3) and a traction balloon (4) arranged outside the catheter (5), which one or more cavities are arranged in the catheter (5), the catheter part is provided with at least one hole, at least one cavity fills and discharges the traction balloon (4) with fluid through the hole, the traction balloon (4) bends to one side when filled with fluid, and the handle (2) can drive the catheter (5) and the traction balloon (4) to rotate, thus realizing a simple and reliable traction.
