Abstract
Intervertebral disk prosthesis comprising an external waterproof multilayered deformable casing surrounding a peripheral partition membrane delimiting an outer space and an inner cavity, wherein the inner cavity is partitioned by vertical walls delimiting at least four cavity compartments configured to be filled with a non-toxic saline solution, and wherein the vertical walls comprise orifices and/or porous membranes configured to induce the saline solution to flow from one cavity compartment toward another upon heterogeneous application of a pressure comprised between 0.05 and 3 MPa in a duration comprised between 10 seconds and 60 minutes, and to revert back to its native compartment upon removal of said pressure in a duration comprised between 10 seconds and 180 minutes, and wherein the walls are distributed asymmetrically in the inner cavity so that a posterior part of the inner cavity comprises fewer and/or larger cavity compartments than an anterior part of the inner cavity.
