Abstract: The invention is directed to a device for the sealing occlusion and/or for the space-filling tamponade of hollow organs or other cavities in the human body, comprising a preferably fully and residually formed balloon (2) which applies a sealing pressure that is as constant as possible to the wall of the organ to be occluded or tamponaded.
