[Problem] To provide a catheter balloon which, when treating calcific aortic stenosis, rheumatic and congenital aortic stenosis, etc., facilitates control of the expanded outer diameter of the stretchable balloon, enables effectively prevention of balloon migration, and can easily be fixed in a prescribed position. [Solution] This catheter balloon (10) is provided with a cylindrical balloon unit (20) formed from a non-stretch material or a low-stretch material, and a band unit (30) manufactured from a material consisting of a stretchable elastic body. The band unit (30) has a diameter shorter than the expanded diameter of the balloon unit (20) in a state in which no expanding force is being applied, and is wound around the middle part of the balloon unit (20). |
