Intended Use

The CODMAN SLIM-LOC™ System is a permanent implant, generally indicated for short-term stabilization of the cervical spine from C2 to C7 employing screw fixation at the anterior face of the vertebral bodies. This product may be employed as an internal fixation device during the time interval required for arthrodesis.

Device Story

System consists of titanium alloy plates and screws for anterior cervical spine stabilization; implanted during surgery to provide internal fixation during arthrodesis. Plates feature integrated screw locking mechanism to prevent screw back-out; various cancellous screw types provided. Used by surgeons in clinical/OR settings. Device provides mechanical stabilization to the cervical spine; benefits patient by maintaining alignment and supporting fusion during healing process.

Clinical Evidence

Bench testing only. Biomechanical testing performed to support the device for its intended use.

Technological Characteristics

Manufactured from ASTM F-136 implant grade titanium alloy. System includes plates with integrated screw locking mechanism and cancellous screws. Mechanical fixation device.

Indications for Use

Indicated for stabilization of cervical spine (C2-C7) via anterior unicortical screw fixation. Patient populations include those with instability due to trauma, correction of cervical lordosis/kyphosis, pseudoarthrosis from failed surgery, primary or metastatic tumors, and advanced degenerative disk disease, spinal canal stenosis, or cervical myelopathy requiring corpectomy.

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 Ms. Wunder:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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 (Act). 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.

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 Eederal 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.
