An intervertebral disk prosthesis or a nucleus replacement prosthesis having an at least partially flexible jacket (3, 4, 5) that encloses a cavity (2) having a variable shape. The jacket (3, 4, 5) is at least partially configured as a semi-permeable membrane (3) for a solvent so that a solution of a substance contained in the cavity (2) can adapt its concentration and its volume to the external load conditions according to the principle of reverse osmosis.
