The invention concerns a method for preparing a non-toxic, sterile, biocompatible, crosslinked collagen material with controlled in vivo biodegradation speed. It consists in subjecting a collagen constituent, either to beta radiation, or to gamma radiation. The collagen material obtained is biodegradable in a few days depending on the type of irradiation used.
L'invention a pour objet un procédé pour la préparation d'un matériau collagénique réticulé, biocompatible, stérile, non toxique et à vitesse de biodégradation in vivo contrôlée. Il comprend le fait de soumettre un composant collagénique à l'état humide, soit à une irradiation par rayonnement béta, soit à une irradiation par rayonnement gamma. Le matériau collagénique obtenu est biodégradable en quelques jours à plusieurs semaines selon le type d'irradiation mis en oeuvre.
