Patent

CA 2236306

The invention concerns a biologically compatible, biologically non-absorbable and non-toxic adhesive composition, for surgical and/or therapeutic use in particular for bonding together biological tissues or with an implanted biological material, characterised in that it contains at least one biodegradable macromolecular polyaldehyde of natural origin, in an aqueous solution such as oxidised starch or a polyaldehyde with similar properties of stability. This composition can further contain one collagenic constituent selected among: collagen having partially lost its helical structure, non-hydrolysed, consisting mostly of alpha chains, rendered soluble in an aqueous medium; native collagen in a concentration less than 5 %. The invention also concerns a method for bonding biological tissues together or to an implanted biological material using this adhesive composition. The invention is useful for preventing post-operative adhesions.

La présente invention concerne une composition adhésive biocompatible, biorésorbable et non toxique, à usage chirurgical et/ou thérapeutique notamment pour la liaison de tissus biologiques entre eux ou avec un biomatériau implanté, caractérisée en ce qu'elle comprend au moins un polyaldéhyde macromoléculaire biodégradable d'origine naturelle, en solution aqueuse tel que de l'amidon oxydé ou un polyaldéhyde ayant des propriétés similaires de stabilité. Cette composition peut comprendre en outre un composant collagénique choisi parmi le collagène ayant perdu au moins partiellement sa structure hélicoïdale, non hydrolysé, constitué majoritairement de chaînes .alpha., solubilisé en milieu aqueux; le collagène natif selon une concentration inférieure à 5 %. L'invention concerne également un procédé de liaison de tissus biologiques entre eux ou à un biomatériau implanté comprenant la mise en oeuvre de cette composition adhésive. L'invention s'applique à la prévention des adhérences post-opératoires.
