Abstract
A balloon has an inflatable portion that forms a tube shape extending in an extending direction in an inflated state, a distal end connecting portion provided to an end portion of the inflatable portion on one side thereof, and a proximal end connecting portion provided to an end portion of the inflatable portion on the other side thereof. At least the inflatable portion includes a plurality of first portions that forms wings in the deflated state and a plurality of second portions that is adjacent to the plurality of first portions in a circumferential direction centered on the center axis. In the process of changing shape from the inflated state to the deflated state, the plurality of second portions moves towards the center axis in advance of the plurality of first portions and thereby forms, in the inflatable portion, indentations recessed toward the center axis.
