OSSDSIGN Cranial PSI (Patient Specific Implant) is a device that replaces native bone in the cranial skeleton. Each Cranial PSI is a patient-specific device specifically created for a patient’s unique anatomical requirements. Cranial PSI consists of a rigid titanium mesh that is largely covered by biocompatible ceramic tiles. The ceramic tiles are in a mosaic pattern that provides space between tiles to allow free circulation of fluids (510(k) no. K161090)
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.
