Abstract
A balloon catheter may include a shaft having a distal side and a proximal side and a balloon provided at the distal side of the shaft. The balloon may have a plurality of wings in a deflated state, with each of the wings having a projection on an outer surface in a wrapped state, and each of the projections having a projecting direction, which is opposite to a wrapping direction of the wing. In a cross section that is perpendicular to a long axis direction of the balloon, a base of the projection may have a base first end part farther from a tip of the wing and a base second end part closer to the tip of the wing, and a tip of the projection may be closer to a base of the wing with respect to a line passing through the base first end part which is perpendicular to a line passing through the base first end part and the base second end part.
