AbstractA method of treating a reconstituted biopolymeric implant which includes the steps of exposing the implant to an aqueous environment so that a final water content of the implant ranges from 5% by weight to a maximal water absorption capacity; and sealing the hydrated implant in a gamma ray-penetrable but bacteria- or virus-impenetrable material. Also disclosed is an implant preparation obtained by the above method.
