Abstract
A folding method of an inflatable balloon disposed on an outer peripheral surface of an inner tube of a balloon catheter is disclosed. The method includes: disposing the balloon to an inner side of a plurality of first blade portions arranged so as to surround a reference position while maintaining a state where pressure is applied to an inside of the balloon; correcting a bend of the balloon by moving the plurality of first blade portions toward the reference position in the state where the pressure is applied to the inside of the balloon; pleating a plurality of wing portions protruding radially outward on the balloon by further moving the plurality of first blade portions toward the reference position to partially press the balloon while gradually discharging the fluid inside the balloon; and folding the balloon along the inner tube.
