Provided is a filling liquid (161) for filling a balloon (170) for a method for occluding a tubular organ, including a microcapsule (162) in which a balloon-dissolving substance that dissolves the balloon (170) is encapsulated, wherein the microcapsule is destroyable by an ultrasonic beam; and a liquid that is harmless in the tubular organ and does not dissolve the balloon. Further provided is a method for terminating a tubular organ occlusion including a step of applying an ultrasonic beam to a balloon (170) that is filled with the filling liquid (161) and occludes a tubular organ, thereby breaking the balloon (170) as a result.
