Abstract:
A surgical balloon comprising, an aggregate of a plurality of balloons closely located with each other,wherein in order to close a space connecting one area in a body to another area thereof so as to block a liquid or a gas flowing through the space, at least one balloon is press-adhered to a portion adjacent to bone tissue, cartilage tissue or hard tissue so as to be fixed thereon while other balloons closely adjacent thereto are indirectly fixed and allowed to expand with the fixed position being maintained, so as to shield a peripheral area; wherein the aggregated balloons include balloons having a high inner pressure and balloons having a low inner pressure that are closely located with each other, the balloons having a high inner pressure being press-adhered and fixed onto a nasal cavity or a rear nostril with other balloons adjacent thereto being allowed to expand to block the nasal cavity and throat heads from communicating with each other wherein a shielding balloon having a low inner pressure contains a balloon inside having a high inner pressure while keeping a positional relationship with contact faces being maintained so that the shielding balloon having a low inner pressure, located outside, is allowed to expand in a direction opposite to the contact face with the fixed balloons having a high inner pressure, located inside thereof, thereby exerting a pressing force in a specific direction.
