The composite prosthesis comprises a textile reinforcement material, one side of which is associated with a polymer matrix which is constituted by a real physical gel of chitosan, forming a visco-elastic mass comprising at least 95% water and having a thickness of at least 1mm. Said chitosan has a degree of acetylation of at most 30%, preferably between 0 and 15% and a molecular weight of at least 300,000 g / mol, preferably 400,000 g / mol. |
