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.

Abstract: Certain embodiments of the invention relate to a method for monitoring the use of sensitive products (16) in which the products and/or their packaging are marked and identified and then the products are marketed while storing successively their references in a CENTRAL FILE, associated with determined user customers and with suppliers, then in stock-management files (30, 30?) and, gradually as they are used at a user customer, in customer files (34, 34?, etc.). If one or more anomalies are found making it possible to qualify a product of determined type as defective (RD), data comprising the reference of the defective product can be automatically and simultaneously transmitted to all of the media of the various files, the reference of the defective product is automatically compared (35, 35?, etc.) with the product references appearing in the files, and in the event of a positive comparison, a warning signal is immediately or substantially immediately triggered.

Abstract: The present invention concerns a method and a system for tracking medical products in which the product (11, 12) and/or its packaging (16) is marked and identified with a first reference (18) that is stored in a first file (20) and the packaged product is shipped (7) to the client for storage for subsequent use for a patient listed in a second file (31). The references of the product are detected (27) automatically and remotely when it is shipped and stored in a third, or stock control, file (28) of the client at the time of an operation.

Abstract: The invention concerns an interspinous stabilizer comprising two members anchoring it to spinous processes of two respective vertebrae, and a body extending along a direction aligning the members, the body, being compressible along the alignment direction by the effect of stress based on a predetermined configuration, the body being adapted to recover spontaneously said predetermined configuration after the stress has ceased, the body comprising a leaf spring with a geometrical generatrix. The anchoring members are capable of fixing the stabilizer to the spinous processes such that the generatrix extends substantially from the front to the rear relative to the patient's body.
