A device for providing an indication concerning the pressure existing in an environment, particularly in human or animal tissue, with a closed capsule (4) to be implanted therein, said capsule (4) having a wall (6) which is partly flexible and being partly filled with a quantity of material (12) which is displaced as a result of movements of the wall (6) and of which, in a reference position of the capsule (4), the surface level (14) with respect to one or more radiopaque markers (10) on the capsule (4) can be detected, so that by means of repeated observations changes in the tissue can be detected. <IMAGE> |
