Balloon dilation catheter with tethered structure
By setting a restraint structure outside the balloon, the problem of unstable shape of the balloon dilation catheter during dilation is solved, achieving cylindrical dilation and reducing delivery resistance, thus improving the effect of vasodilation.

AI Technical Summary
Technical Problem
Existing balloon dilation catheters cannot maintain a cylindrical shape during dilation, resulting in a "dumbbell" effect and failing to effectively dilate vascular stenosis lesions.
Method used
A restraint structure is installed outside the balloon. The restraint structure is in a preset shape to match the balloon and is fixed to the tube body to ensure that the balloon maintains a cylindrical shape when it expands and can slide during delivery to reduce resistance.
Benefits of technology
It achieves complete balloon expansion, avoids the "dumbbell" effect, improves expansion effect, and reduces delivery resistance.

Abstract
The application relates to a balloon dilatation catheter with a binding structure, which comprises the binding structure and a balloon dilatation catheter (quick exchange type or OTW type). The balloon dilatation catheter is divided into two parts of a balloon and a tube body. The binding structure is wholly sleeved on the outer periphery of the balloon, and at least one end of the binding structure is fixed to the balloon dilatation catheter tube body; the binding structure is in a preset shape, specifically a cylindrical structure, and the shape of the balloon in an expanded state matches the preset shape of the binding structure. After the balloon is expanded, the binding structure can effectively bind the external shape of the balloon, ensures that the balloon is expanded according to the preset shape of the binding structure, forms a relatively complete cylindrical shape, does not produce a dumbbell effect, and thus realizes sufficient expansion of a plaque position.
