Beschreibung
Zusammenfassung:	The invention provides a cardiovascular intervention balloon catheter. The surface of a balloon is a rough surface, and the structure of the rough surface is of nanometer scale; the surface of the balloon is coated with a hydrophilic coating. The surface of the cardiovascular intervention balloon catheter is modified to form a plurality of nanometer scale structures, the mechanical performance of the nanometer scale structures is not changed in the deformation process of the balloon, and meanwhile the friction force on a contact surface between the bracket and the balloon is increased, so that the friction force on the contact surface between the bracket and the balloon is enhanced, and the bracket is prevented from falling off from the balloon in a conveying process.
