  • Cartilaginous and osteochondral substitute comprising multilayer structure and use thereof
    Patent number: 9155818
    Abstract: The present invention relates to a multilayer structure (1) including a first upper layer (2) consisting of an organic matrix including collagen and at least a lower layer (3, 4, . . . 10) consisting of a composite matrix including hydroxylapatite and collagen. Furthermore, the present invention relates to a cartilaginous substitute including said multilayer structure (1) as well as an osteochondral substitute including said multilayer structure (1). Finally, the present invention relates to the use of said multilayer structure (1) for the preparation of said cartilaginous substitute and said osteochondral substitute for the treatment of cartilaginous defects and osteochondral defects or for the neo-formation of a cartilaginous tissue and/or a subchondral bone tissue.

  • Pin for Anchorage of Articular Prosthesis, Articular Prosthesis Comprising Said Pin, Tibial Component and Articular Prosthesis for the Knee Comprising Said Tibial Component
    Publication number: 20080200957
    Abstract: A pin for the anchoring of articular prostheses includes a connecting portion (4) with a prosthesis (2) and an engagement portion (5) in a hole obtained within a bone. The engagement portion (5) is at least partly deformable in a radial direction and in a resilient way, in order to allow the instantaneous blocking of the pin (1) in the hole and the primary fixing of the prosthesis (2) on the bone, so as to al low an easy primary fixing of the prosthesis by simply introducing with a pressure the connecting portion in the hole obtained within the bone itself.
