This application discloses a restraint balloon, its preparation method, and a balloon catheter, relating to the field of medical devices. The restraint balloon includes: an expandable balloon body; and a restraint component, composed of fibrous strands and fixed to the outer surface of the balloon body, used to limit the radial deformation of the balloon body during expansion. The restraint balloon of this application can limit the radial deformation of the balloon body, effectively dispersing stress during expansion. It can be used for the clinical treatment of non-vascular lumen stenosis. Because the fibrous strand restraint component can deform synchronously with the balloon body during expansion, and can contract to a near-initial state along with the balloon body after decompression due to its own elastic recovery characteristics, it significantly reduces the difficulty of balloon retraction, improving the safety and convenience of surgical procedures. It also has the advantages of low cost, high yield, simple processing, and high manufacturing efficiency.
