Intended Use

The RIGEL™ 3DR Anterior Cervical Corpectomy System is indicated for vertebral body replacement in the cervical spine (C2-T1) in skeletally mature patients. The RIGEL™ 3DR Anterior Cervical Corpectomy System is intended to replace a diseased or damaged vertebral body caused by fracture, or tumor, or for reconstruction following corpectorned to achieve decompression of the spinal cord and neural tissues in cervical degenerative disorders. The System is intended to be used with supplemental fixation that has been cleared by the FDA for use in the cervical spine. The System is designed for use with autogenous and/or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft as an adjunct to fusion. The System is also intended to restore the integrity of the spinal column even in the absence of fusion for a limited time period in patients with advanced stage tumors involving the cervical spine in whom life expectance is of insufficient duration to permit achievement of fusion, with bone graft used at the surgeon's discretion.

Device Story

Vertebral body replacement system; provides structural stability/mechanical support to cervical spine post-corpectomy. Implants additively manufactured; used with supplemental fixation cleared for cervical spine. Surgeon-implanted in clinical setting. Restores spinal column integrity; facilitates fusion via bone graft; supports palliative care in advanced tumor cases. Benefits: spinal decompression, structural support, stabilization.

Clinical Evidence

Bench testing only. Mechanical performance assessed via static/dynamic compression (ASTM F2077-18), static/dynamic torsion (ASTM F2077-18), and subsidence testing (ASTM F2267-04). No clinical data provided.

Technological Characteristics

Implants: Titanium-6 Aluminum-4 Vanadium ELI (ASTM F3001), additively manufactured. Instrumentation: Stainless Steel (ASTM F899). Sterile, single-use. Mechanical fixation device; no software or energy source.

Indications for Use

Indicated for vertebral body replacement in the cervical spine (C2-T1) in skeletally mature patients with diseased/damaged vertebrae due to fracture, tumor, osteomyelitis, or cervical degenerative disorders requiring decompression. Used with supplemental fixation and bone graft. Also indicated for spinal column integrity restoration in patients with advanced-stage cervical tumors where fusion is not expected.

Regulatory Classification

Identification

A spinal intervertebral body fixation orthosis is a device intended to be implanted made of titanium. It consists of various vertebral plates that are punched into each of a series of vertebral bodies. An eye-type screw is inserted in a hole in the center of each of the plates. A braided cable is threaded through each eye-type screw. The cable is tightened with a tension device and it is fastened or crimped at each eye-type screw. The device is used to apply force to a series of vertebrae to correct “sway back,” scoliosis (lateral curvature of the spine), or other conditions.

Dear Mr. Bauman:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

## VII. INDICATIONS FOR USE

The RIGEL™ 3DR Anterior Cervical Corpectomy System is indicated for vertebral body replacement in the cervical spine (C2- T1) in skeletally mature patients. The RIGEL™ 3DR Anterior Cervical Corpectomy System is intended to replace a diseased or damaged vertebral body caused by fracture, osteomyelitis, or tumor, or for reconstruction following corpectomy performed to achieve decompression of the spinal cord and neural tissues in cervical degenerative disorders. The System is intended to be used with supplemental fixation that has been cleared by the FDA for use in the cervical spine. The System is designed for use with autogenous and/or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft as an adjunct to fusion. The System is also intended to restore the integrity of the spinal column even in the absence of fusion for a limited time period in patients with advanced stage tumors involving the cervical spine in whom life expectance is of insufficient duration to permit achievement of fusion, with bone graft used at the surgeon's discretion.

# VIII. PREDICATE DEVICE COMPARISON

The RIGEL™ 3DR Anterior Cervical Corpectomy System has the same intended use, indications for use, labeling, and technological characteristics as the predicate systems, including the same design features, geometries, and a similar size range of footprints.

The mechanical performance profile of the RIGEL™ 3DR Anterior Cervical Corpectomy System was assessed through static and dynamic testing in accordance with the following test methods:

- Static and dynamic compression testing (ASTM F2077-18)
- Static and dynamic torsion testing (ASTM F2077-18)
- Subsidence testing (ASTM F2267-04) ●

# X. CONCLUSIONS

The RIGEL™ 3DR Anterior Cervical Corpectomy System has the same intended use, indications for use, labeling, and technological characteristics as the predicate systems, including the same design features, geometries, and a similar size range of footprints. Performance data demonstrate that the RIGEL™ 3DR Anterior Cervical Corpectomy System is substantially equivalent to legally marketed predicate systems.
