Title (EN) RESORBABLE CROSSLINKED FORM STABLE MEMBRANE
(FR) MEMBRANE STABLE SOUS FORME RÉTICULÉE RÉSORBABLE
Abstract:
(EN) The invention relates to resorbable crosslinked form stable membrane which comprises a composite layer of collagen material and inorganic ceramic particles containing 1.5 to 3.5 weight parts of inorganic ceramic for 1 weight part of collagen material, sandwiched between two layers of elastic pretensed collagen material (collagen material that has been stretched such as to be in the linear/elastic region of the stress-strain curve), the collagen material comprising 50-100 % (w/w) collagen and 0-50 % (w/w) elastin, and has shape and dimensions suitable for use in human tissue regeneration outside the oral cavity in rhinoplasty, postlateral spinal fusion or orbital reconstruction.
(FR) L'invention concerne une membrane stable sous forme réticulée résorbable qui comprend une couche composite constituée d'un matériau de collagène et de particules céramique inorganiques contenant de 1,5 à 3,5 parties en poids de céramique inorganique pour 1 partie en poids de matériau de collagène, en sandwich entre deux couches de matériau de collagène précontraint élastique (matériau de collagène qui a été étiré de façon à être dans la région linéaire/élastique de la courbe de contrainte-déformation), où le matériau de collagène comprenant de 50 à 100 % (p/p) de collagène et de 0 à 50 % (p/p) d'élastine. La membrane selon l'invention a une forme et des dimensions se prêtant à une utilisation en régénération tissulaire chez l'homme, hors cavité buccale en rhinoplastie, fusion spinale post-latérale ou reconstruction orbitale.
