For example, when cannulating, the appropriate size and shape of the catheter should be selected to reduce irritation and damage; the urinary catheter is inserted through the urethra into the bladder, and through the drainage effect of the pipe, it helps the patient to urinate, etc. Since the catheter has a wide range of uses, it can be used to treat coronary and peripheral arterial calcified lesions by using the catheter to enter the patient's blood vessels for treatment;

[0003] When the catheter for treating coronary and peripheral arterial calcified lesions is in use, the stent mesh is usually directly sleeved on the surface of the shock wave balloon for use, which causes the stent mesh to be easily detached or deviated due to the influence of the expansion of the shock wave balloon, thereby affecting the treatment effect of the catheter for treating coronary and peripheral arterial calcified lesions. At the same time, the catheter for treating coronary and peripheral arterial calcified lesions cannot improve the expansion efficiency of the shock wave balloon when in use, which causes the shock wave balloon to expand slowly, thereby increasing the treatment time for treating coronary and peripheral arterial calcified lesions.
