Device features T-profile with two semi-circular tabs (0.2 mm thick) and two spring-like projections designed to lodge in the diploe of surrounding cranial bone. Surgeons secure the clip using 1.5 mm Ti Alloy Bone Screws inserted laterally into the diploe. Device is single-use, MRI compatible, and low-profile (4.2 mm height). Used in clinical/surgical settings by neurosurgeons to stabilize bone flaps, facilitating healing and structural integrity of the cranium. ## Clinical Evidence No clinical data; bench testing only. ## Technological Characteristics Material: Titanium alloy. Dimensions: 11.5 mm length, 9.0 mm width, 4.2 mm height. Fixation: 1.5 mm Ti Alloy Bone Screws. Design: T-profile with spring-loaded projections for diploe engagement. Single-use. MRI compatible. ## Regulatory Identification A preformed alterable cranioplasty plate is a device that is implanted into a patient to repair a skull defect. It is constructed of a material, e.g., tantalum, that can be altered or reshaped at the time of surgery without changing the chemical behavior of the material. ## Predicate Devices - Synthes Midfacial System ([K953806](/device/K953806.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

CLASSIFICATION | Class II, 21 CFR 882.5320 and 882.5360 | | PREDICATE DEVICE | Synthes Midfacial System (K953806) | | DESCRIPTION | Synthes Cranial Spring Clip (CSC) is intended to reattach a cranial bone flap to the surrounding cranium after a craniotomy procedure. The CSC has a T-profile, which consists of two semi-circular tabs, and two projections that are bent into springs to lodge in the diploe of the cranial bone surrounding the osteotomy. The two tabs are 0.2 mm thick and rest on the superior surfaces of the cranial flap and the surrounding cranial bone. The CSC has a low profile, is 11.5 mm in length, 9.0 mm in width, and is 4.2 mm in height (0.2 mm above the cranial surface). 1.5 mm Ti Alloy Bone Screws will be inserted laterally through the CSC and into the diploe. The CSC is for single use only. | | INTENDED USE | Synthes CSC is intended to reattach a cranial bone flap to the surrounding cranium after a craniotomy procedure. | The CSC is contraindicated in the following situations: in patients with a skull thickness less than 4 mm; or when the gap surrounding the bone flap is greater than 2 mm. The CSC is MRI compatible. {1}------------------------------------------------ Food and Drug Administration 9200 Corporate Boulevard Rockville MD 20850 MAR 1 6 1998 Ms. Sheri L.
