Abstract
A prothesis intended to be introduced into a bodily canal which includes a flexible tube for preserving the normal passage cross section of the bodily canal and a holding device for immobilizing the flexible tube in position in the canal. The holding device is a tubular structure and is radially deformable so that it can pass from a first state in which its cross section is at most equal to that of the bodily canal into which it is to be introduced to a second state in which its cross section is such that the holding device bears on the wall of an orifice of the bodily canal emerging in a natural cavity. The holding device is linked at a distance to the flexible tube.
