It is intended for surgical use by neurosurgeons or qualified clinicians in a clinical or hospital setting. The material is applied to the cranial defect site to restore structural integrity. It functions as a bone void filler or prosthetic material for cranioplasty procedures. The device provides a stable, biocompatible medium for defect reconstruction, potentially improving patient outcomes by restoring cranial contour and protection. ## Clinical Evidence Bench testing only. Performance testing demonstrated functional equivalence to the predicate device. ## Technological Characteristics Methyl methacrylate resinous material for cranioplasty. Formulated with materials identical to the predicate device. Class II device (Product Code GXP). ## Regulatory Identification Methyl methacrylate for cranioplasty (skull repair) is a self-curing acrylic that a surgeon uses to repair a skull defect in a patient. At the time of surgery, the surgeon initiates polymerization of the material and forms it into a plate or other appropriate shape to repair the defect. ## Predicate Devices - Codman Cranioplastic, Acrylic Cranioplasty Material ([K873689](/device/K873689.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. AUG 3 1 2000 If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations. This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market. {2}------------------------------------------------ ## Page 2 -- Mr. Bryan Barr If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at additionally 607.10 for m This alagilestions on the promotion and advertising of your device, (201) 594-1037.
