Abstract
The invention concerns a method for preparing a non-toxic, sterile, biocompatible, crosslinked collagen material with controlled in vivo biodegradation speed. It consists in subjecting a collagen constituent, either to beta radiation, or to gamma radiation. The collagen material obtained is biodegradable in a few days depending on the type of irradiation used.
