The NeuroVention Cranial Fixation System is intended for use as a burr hole cover and/or skull bone fixation following craniotomy, cranioplasty, or craniectomy surgery.
Device Story
NeuroVention Cranial Fixation System comprises titanium, titanium alloy, and PEEK plates, burr hole covers, and screws used for cranial bone fixation. System includes manual surgical instruments (screwdriver, drivers, forceps, drill bit) for implantation. Provided non-sterile; requires steam sterilization by user facility. Used in OR by neurosurgeons to stabilize bone flaps or cover burr holes post-craniotomy/craniectomy. Surgeon selects appropriate implant configuration based on patient anatomy and surgical needs. Device provides rigid fixation; mechanical performance verified via static compression, skull conformity, and screw pushout/torque testing. MR conditional status established for 1.5T and 3.0T environments.
Clinical Evidence
Bench testing only. No clinical data was required. Mechanical testing included static compression, skull conformity, screw axial pushout, and screw torque to failure (per ASTM F543-13). Usability testing was performed for the drill bit. All testing met or exceeded established protocols and acceptance criteria.
Technological Characteristics
Materials: Titanium (ASTM F67), Ti-6Al4V ELI (ASTM F136), PEEK (ASTM F2026), Stainless Steel (ASTM F899). Components: Plates, burr hole covers, screws. Manual instrumentation: Screwdriver, drivers, forceps, drill bit. Sterilization: Steam (user-performed). MR Conditional (1.5T/3.0T).
Indications for Use
Indicated for burr hole coverage and skull bone fixation in patients undergoing craniotomy, cranioplasty, or craniectomy surgery.
Regulatory Classification
Identification
A burr hole cover is a plastic or metal device used to cover or plug holes drilled into the skull during surgery and to reattach cranial bone removed during surgery.

Each is provided non-sterile single use and is made of titanium as per ASTM F67, titanium alloy (Ti-6AI4V ELI) implantable components that comply with ASTM F136 or PEEK per ASTM F2026. Class I exempt instrumentation is available for delivery and removal: Screwdriver Adapter (handle), Torx Drivers, Forceps. Additionally, a Class II Drill bit is included to create pilot holes for the screws.
#### Indications and Intended Use
The NeuroVention Cranial Fixation System is intended for use as a burr hole cover and/or skull bone fixation following craniotomy, cranioplasty, or craniectomy surgery.
#### Technological Characteristics and Substantial Equivalence
Documentation was provided to demonstrate that the NeuroVention Cranial Fixation System is substantially equivalent to the legally marketed predicates. It consists of a storage module that contains the various shapes of implants, screws and implantation instruments. The devices and accessories included in the Subject device and the predicate devices are both burr hole covers, cranioplasty plates and screws. The NeuroVention Cranial Fixation System is substantially equivalent to the predicate devices in intended use, site of application, patient populations of use, mechanical performances, basic design, and operating principles. The NeuroVention Cranial Fixation System is comparable to its predicate in size and materials. Mechanical testing shows the mechanical strength of the Subject device to be equivalent or better than the predicate devices.

Performance Data The potential hazards have been evaluated and controlled through Risk Management.
> All testing met or exceeded the requirements as established by the test protocols and applicable standards. A review of the mechanical data indicates that the components of the Subject device are capable of withstanding expected loads without failure. The Subject device was therefore found to be substantially equivalent to the Predicates. Clinical data was not needed to support the safety and effectiveness of the Subject Device.
The following mechanical testing was performed:
- Static Compression
- . Skull Conformity
- Screw Axial Pushout •
- . Screw Torque to Failure per ASTM F543-13
- . Usability testing of Drill Bit
All results passed acceptance criteria and were equivalent or better when compared to the predicates.
Biocompatibility The components of the predicate device for the implantable components, are manufactured from the same titanium and titanium alloy for implantable components in conformity with ASTM F67-13 and ASTM F136. The Subject device also has a PEEK configuration made from VESTAKEEP by Evonik Industries per ASTM F2026. The instruments are made of the same stainless steel in conformance with ASTM F899. These materials are well known and well characterized have been used in other commercially available cranial implants. The predicate devices are used for the same duration and come into contact with the patient in the same manner and in the same body parts. The materials are considered to be biocompatible and have a long history of safe use as part of medical devices marketed in the United States and around the world. The Subject and predicate devices as well as a large number of implantable devices are manufactured in the same way with the same materials.
- Conclusion Based on design, materials, intended use, technological characteristics, and comparison to predicate devices, the Subject Neurovention Cranial Fixation System has been shown to be substantially equivalent to legally marketed predicate device.
