The invention provides a multi-layer membrane comprising a matrix layer predominantly of collagen II and having an open sponge-like texture, and at least one barrier layer having a close, relatively impermeable texture. Such a membrane is particularly suitable for use in guided tissue regeneration, in particular for use in vivo in the reconstruction of bone or cartilage tissue.
L'invention concerne une membrane multicouche comprenant une couche matrice sensiblement à base de collagène II et présentant une texture spongieuse ouverte et au moins une couche barrière présentant une texture fermée relativement imperméable. Cette membrane convient particulièrement à une utilisation en vue d'une régénération tissulaire guidée, plus particulièrement à une utilisation in vivo dans la reconstruction du tissu osseux et cartilagineux.
