Intended Use

The VERTE-STACK® Spinal System is a vertebral body replacement device intended for use in the thoracolumbar spine (T1-L5) to replace a collapsed, damaged, or unstable vertebral body due to tumor or trauma (i.e., fracture). The VERTE-STACK® Spinal System is to be used with supplemental fixation. Specifically, the VERTE-STACK® device is to be used with the Medtronic Sofamor Danek ZPLATE II Anterior Fixation System, the DYNALOK™ CLASSIC Spinal System, the VANTAGE™ Anterior Fixation System, the TSRH® Spinal System, the CD HORIZON® Spinal System, the GDLH® Spinal System and/or their successors. Additionally, the VERTE-STACK® device is intended to be used with bone graft.

Device Story

Vertebral body replacement system consisting of stackable, hemi-cylindrical center and add-on cages; used to reconstruct vertebral space following corpectomy. Components available in various lengths, diameters, and angulations to accommodate patient anatomy. Implanted by surgeons in clinical/OR settings. Requires supplemental anterior/posterior spinal instrumentation for stability; PEEK constructs compatible with stainless steel or titanium fixation; titanium constructs restricted to titanium fixation. Device provides structural support to replace damaged vertebrae; facilitates fusion when used with bone graft.

Clinical Evidence

No clinical data. Bench testing only.

Technological Characteristics

Materials: PEEK-OPTIMA LT1, Tantalum, titanium, or titanium alloy. Form factor: Stackable hemi-cylindrical cages. Energy source: None (mechanical). Connectivity: None. Sterilization: Not specified.

Indications for Use

Indicated for patients with collapsed, damaged, or unstable vertebral bodies in the thoracolumbar spine (T1-L5) resulting from tumor or trauma (fracture). Must be used with supplemental fixation and bone graft.

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.

- Proprietary Trade Name: VERTE-STACK® Spinal System II.
- Classification Name/Product Code: Spinal Intervertebral Body Fixation Orthosis III. (21 CFR 888.3060)
- Product Code: MQP IV.

#### V. Product Description

The VERTE-STACK® device consists of hemi-cylindrical center cages of various lengths and diameters, as well as hemi-cylindrical add on cages of various lengths, diameters and angulation. The assembled VERTE-STACK® device consists of three components (one hollow center cage, and two hollow add-on cages). The VERTE-STACK® components can be rigidly locked into a variety of configurations, with each construct being tailor-made for the individual case.

The design of the VERTE-STACK® device includes a variety of stackable components of different sizes and heights. The stackable components are designed to suit the individual patient pathology.

The VERTE-STACK® device may be used individually, or two or more may be stacked together in order to accommodate the individual anatomical requirements of the vertebral space created by the corpectomy.

The VERTE-STACK® Spinal System implant components are made of medical grade PEEK-OPTIMA LT1 along with a marker made from either Tantalum or titanium. Alternatively, VERTE-STACK® Spinal System may be manufactured from titanium alloy.

The VERTE-STACK® Spinal System must be used with additional anterior and/or posterior spinal instrumentation to augment stability. VERTE-STACK® constructs manufactured from PEEK may be used with stainless steel or titanium supplemental

fixation devices. Titanium VERTE-STACK® constructs may not be used with stainless steel supplemental fixation devices.

The purpose of this submission was to modify the wording of the VERTE-STACK® Spinal System package insert by removing certain contraindications and by including a NOTA BENE for potential factors to consider with regards to when not to use this device. The rewording of the document makes it more consistent with that of the package insert for the CD HORIZON® Spinal System, which may be used as the supplemental fixation device for the VERTE-STACK® device.

#### V. Indications

The VERTE-STACK® Spinal System is a vertebral body replacement device intended for use in the thoracolumbar spine (T1-L5) to replace a collapsed, damaged, or unstable vertebral body due to tumor or trauma (i.e., fracture). The VERTE-STACK® Spinal System is to be used with supplemental fixation. Specifically, the VERTE-STACK® device is to be used with the Medtronic Sofamor Danek ZPLATE II Anterior Fixation System, the DYNALOK™ CLASSIC Spinal System, the VANTAGE™ Anterior Fixation System, the TSRH® Spinal System, the CD HORIZON® Spinal System, the GDLH® Spinal System and/or their successors. Additionally, the VERTE-STACK® device is intended to be used with bone graft.

#### VI. Substantial Equivalence

Documentation was provided which demonstrated that the subject VERTE-STACK® Spinal System components are substantially equivalent to the previously cleared VERTE-STACK® Spinal System components most recently cleared in K061938, SE 08/15/2006; and to the CD HORIZON® Spinal System, as cleared in K061304, SE 07/18/2006.

Dear Mr. Chin:

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 (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. 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.
