Abstract:
Provided is a balloon for a balloon catheter such that it is possible to efficiently incise a lesioned part, while being able to easily fix a balloon to the lesioned part and prevent the shifting of the balloon from the lesioned part. This balloon (2) has a balloon body (20) that has a straight tube part (23), a proximal-side tapered part (22), a proximal-side sleeve part (21), a distal-side tapered part (24), and a distal-side sleeve part (25), said balloon body (20) having a band-shaped region (40) which extends in the longitudinal axis direction (x). The band-shaped region (40) includes a first region (41) composed of a projecting part whose height from the outer surface of the balloon body (20) is (H), and a second region (42) whose height is less than (H). The first region (41) is disposed in the straight tube part (23), and the surface roughness of the second region (42) is greater than the surface roughness of the first region (41).
