Abstract: The invention relates to a tubular sleeve for the atraumatic treatment of hollow organs, wherein the sleeve is folded in an initial state and can be unfolded in order to lie against an inner wall of a hollow organ in a final state. The sleeve is characterized in that the sleeve is formed of an outer wall and an inner wall, which are arranged concentrically to each other, wherein the outer wall and the inner wall are tightly connected to each other at ends thereof in such a way that an approximately tubular compartment is formed in the region between the outer wall and the inner wall and the folding of the sleeve is directed about a sleeve longitudinal axis.
