Biocompatible compositions comprising a biocompatible thickening polymer and a chitosan derivative

Abstract

Biocompatible compositions, in particular for the preparation of a biodegradable coating for medical articles, include a biocompatible thickening polymer and a chitosan derivative comprising D-glucosamine units of the following formula (I): wherein X is an alditolic or aldonic polyol residue of the following formula (II): wherein: R is CH2 or CO; R1 is hydrogen, a monosaccharide moiety or an oligosaccharide moiety; R2 is OH or NHCOCH3. The present invention also relates to uses of the disclosed compositions, to a kit of parts including a composition in powder form and to a method for the preparation of a biocompatible composition in gel form. The biodegradable coating shows a good and long-lasting adhesion to the surface of a medical article and allows to improve both the coating operations and the effectiveness in preventing any biofilm formation on the medical article.
