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 Titanium DYNALOK™ CLASSIC Spinal System, the VANTAGE™ Anterior Fixation System, the Titanium TSRH® Spinal System, the Titanium CD HORIZON® Spinal System or the Titanium GDLH® Spinal System. Additionally, the VERTE-STACK™ device is intended to be used with bone graft.
Device Description
The VERTE-STACK™ device is a stackable spacer, which inserts between vertebral bodies in the anterior thoracic and lumbar spine. The device is intended for vertebral body replacement to aid in the surgical correction and stabilization of the spine. The construct is not intended to be employed as a stand-alone device. The VERTE-STACK ™ device is fabricated and manufactured from titanium alloy. Alternatively the device may be manufactured from POLYETHERETHERKETONE (PEEK OPTIMA LT) and includes a tantalum marker. 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 anatomy. 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 must be used with additional anterior and/or posterior spinal instrumentation to augment stability. VERTE-STACK™ constructs manufactured with 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 is to offer a titanium version of the previously cleared VERTE-STACK™ Spinal System components.
More Information

Not Found

No
The description focuses on the mechanical design and materials of a spinal implant, with no mention of software, algorithms, or data processing that would indicate AI/ML.

Yes
The device is a vertebral body replacement device intended to treat conditions like tumor or trauma by correcting and stabilizing the spine, which is a therapeutic function.

No

The device is described as a vertebral body replacement device and a stackable spacer, intended for surgical correction and stabilization of the spine, not for diagnosing conditions.

No

The device description explicitly states the device is fabricated and manufactured from titanium alloy or PEEK, indicating it is a physical implant, not software.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
  • VERTE-STACK™ Function: The VERTE-STACK™ Spinal System is a physical implant designed to replace a damaged vertebral body in the spine. It is a surgical device used in vivo (within the body) for structural support and stabilization.

The provided text clearly describes a surgical implant, not a device that analyzes biological samples.

§ 888.3060 Spinal intervertebral body fixation orthosis.

(a)
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.(b)
Classification. Class II.

Dear Dr. Treharne:

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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), 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 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
