The invention concerns a method for preparing an acellular organic tissue for revitalisation by means of the reimplantation of living cells, said method involving the following stages: preparing the acellular tissue on an essentially flat surface, creating a plurality of holes on the surface of the tissue, distributed all over said surface and positioned so that they penetrate at least through a portion of the thickness of said tissue. The holes are suitable for containing the living cells when they are reimplanted. The invention also includes a device for implementing said method, characterized in that it comprises - one ore more needles (1) arranged in a holder (20); - a source of electric power (4) connected to said one or more needles.
