Title (EN) BIOLOGICAL TISSUE-REINFORCING MATERIAL
(FR) MATÉRIAU DE RENFORCEMENT DE TISSU BIOLOGIQUE
Abstract:
(EN) Provided is a biological tissue-reinforcing material including a laminated structure, the laminated structure including: a fiber structure, sponge body, or film made of a bioabsorbable polymer; and a film made of etherified cellulose that is produced through etherification of hydroxy groups of cellulose. The biological tissue-reinforcing material is capable of more reliably reinforcing weakened tissue while preventing air leakage or fluid leakage without using fibrin glue, which is a blood product.
(FR) L'invention concerne un matériau de renforcement de tissu biologique comprenant une structure stratifiée, la structure stratifiée comprenant : une structure fibreuse, un corps spongieux ou un film en un polymère bioabsorbable; et un film en cellulose éthérifiée qui est produite par éthérification de groupes hydroxy de cellulose. Le matériau de renforcement de tissu biologique peut renforcer de manière plus fiable un tissu affaibli tout en empêchant une fuite d'air ou une fuite de fluide sans utiliser de colle à la fibrine, qui est un produit sanguin.
