Abstract
The present invention relates to a biocompatible collagenous material which is non-toxic and biodegradable in less than one month, preferably in less than one week. This material comprises collagen and at least one hydrophilic macromolecular additive which is chemically non-reactive towards the collagen, with the collagen having at least partially lost its helical structure and being crosslinked. The invention also relates to a process for obtaining such a material. The collagenous material according to the invention is used, in particular, for preventing post-operative adhesions.
