The medical balloon (1; 2; 3; 4; 5) has a relatively small contour diameter after the pressure of the balloon is released, and has a good capability of passing through a diseased region. The medical balloon (1; 2; 3; 4; 5) comprises a balloon conical portion (121, 122) and a balloon straight segment (11).
