Abrégé
(EN)
An implantable device for facilitating the healing of voids in bone, cartilage and soft tissue is disclosed. A preferred embodiment includes a cartilage region comprising a polyelectrolytic complex joined with a subchondral bone region. The cartilage region, of this embodiment, enhances the environment for chondrocytes to grow articular cartilage; while the subchondral bone region enhances the environment for cells which migrate into that region's macrostructure and which differentiate into osteoblasts. A hydrophobic barrier exists between the regions, of this embodiment. In one embodiment, the polyelectrolytic complex transforms to hydrogel, following the implant procedure.
(FR)
L'invention porte sur un dispositif implantable favorisant le comblement des vides dans les os, les cartilages et les tissus mous. Dans l'exécution préférée la zone du cartilage L'exécution préférée comporte une zone cartilagineuse comprenant un complexe polyélectrolytique lié à une zone sous-chondrale de l'os. Ladite zone cartilagineuse renforce l'environnement qui permet aux chondrocytes de produire du cartilage articulaire, tandis que la zone sous-chondrale de l'os renforce l'environnement qui permet aux cellules migrant vers la macrostructure de la zone de se différentier en ostéoblastes. Dans ladite exécution il existe une barrière hydrophobe entre les zones. Dans une autre exécution, le complexe polyélectrolytique se transforme en hydrogel après l'implantation.
