IMPLANT FOR TISSUE REGENERATION COMPRISING A SUTURABLE CHITOSAN HYDROGEL

摘要

The present invention concerns an implant for tissue regeneration in the form of a colorectal patch or a vascular substitute, characterised in that it consists at least partly of a physical chitosan hydrogel having a degree of acetylation (DA) less than or equal to 15%, characterised in that parameter P, corresponding to the product of the weight average molecular mass Mw of chitosan expressed in kg/mol multiplied by the concentration of chitosan in the hydrogel expressed as a mass % relative to the total mass of the hydrogel, is greater than or equal to 1500 %.kg/mol.
