DEVICE: PEEK Patient Specific Cranial/Craniofacial Implant(PSCI) (06903195108596)

An implantable shield designed to repair larger skull defects that is preformed before surgery and typically made of sheets of material [e.g., stainless steel, vitallium, titanium (Ti), plastic resins] that cannot be reshaped at the time of surgery without changing the physical or chemical properties of the material. The device is generally preformed with a central convex curvature matching the curvature of the forehead, side, or rear areas of the human adult skull; it is usually fixed to the intact cranial bones using screws and/or other fasteners. The device is used to repair defects due to injury, surgical intervention for tumour removal, congenital anomaly, or disease.
