Abstract: A cranial prosthetic comprises a perforated plate, wherein the perforations comprise a plurality of holes substantially equidistant from a central point. One such cranial prosthetic comprises a curved perforated plate, wherein the perforations comprise four holes substantially equidistant from a central point. In an example, the perforated plate also comprises an additional hole at the central point, detachable screw/suture fixing tabs for attaching the cranial prosthetic to the cranium via screws/sutures, detachable securing means consisting of flaps that secure the electrode when closed, and indentations in the form of channels suitable for recessing extension leads with at least one exit point, which connect individual electrodes to the main lead. Removable protective caps may be placed over the detachable securing means when closed.

Abstract: This specification generally relates to cranial prosthetics and their use in therapy. More specifically the specification relates to a cranial prosthetic, which comprises a perforated plate, wherein the perforations comprise a plurality of holes substantially equidistant from a central point. One such cranial prosthetic comprises a curved perforated plate, wherein the perforations comprise four holes substantially equidistant from a central point. The plate also comprises an additional hole at the central point, detachable screw/suture fixing tabs for attaching the cranial prosthetic to the cranium via screws/sutures, detachable securing means consisting of flaps that secure the electrode when closed, and indentations in the form of channels suitable for recessing extension leads with at least one exit point, which connect individual electrodes to the main lead.
