PROBLEM TO BE SOLVED: To provide a balloon catheter for treating an aneurysm, especially dissociative aneurysm of the aorta, in an early stage without surgical treatment. SOLUTION: An instrument of treating dissociative aneurysm of the aorta has a flexible bag-like member 2 at a distal end of a catheter 1. When this bag-like member 2 does not receive fluids inside, the member 2 becomes a flat film shape. When this member 2 receives the fluids, the member 2 becomes a tube shape. An internal side of the film-like member 3a and an external side of the film-like member 3b, both of which comprise the bag-like member 2, are partially joined. |
