No
The device description and intended use focus on the mechanical properties and configuration of the implant, with no mention of AI or ML capabilities.
Yes
The device is described as restoring biomechanical integrity to the spinal column and is used to replace damaged vertebral bodies due to tumor or trauma, aiming to improve or cure a pathological condition.
No
The device, Theken VU VBR SYSTEM, is described as an implant used to replace damaged vertebral bodies and restore spinal integrity, not to diagnose medical conditions.
No
The device description clearly states it is comprised of physical components (cages and spacers) made of material, indicating it is a hardware device, not software-only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
- Device Description and Intended Use: The Theken VU VBR SYSTEM is a surgical implant designed to replace a damaged vertebral body in the spine. It is a physical device implanted into the body to provide structural support and restore biomechanical integrity.
- Lack of Biological Sample Testing: The description and intended use do not involve testing any biological samples from the patient. The device is used directly within the patient's body.
Therefore, based on the provided information, the Theken VU VBR SYSTEM is a surgical device/implant, not an in vitro diagnostic.
N/A
Intended Use / Indications for Use
The Theken VU VBR SYSTEM is indicated for use in the thoracolumbar spine (T1-L5) to replace a collapsed, damaged, or unstable vertebral body due to tumor or trauma (e.g., fracture).
The Theken VU VBR SYSTEM is designed to restore the biomechanical integrity of the anterior, middle, and posterior spinal column even in the absences of fusion for a prolonged period. Bone graft material is recommended to be packed into the interior openings of the device prior to implantation.
The Theken VU VBR SYSTEM is intended to be used with supplemental internal spinal fixation systems, such as the Theken BodyForm Thoracolumbar Fixation System(K983622, Approved 12/98) or the Theken Coral Pedicle Screw System (K041592, Approved 9/04).

Device Description
The Theken VU VBR SYSTEM is comprised of rounded rectangular and rectangular cages with fenestrations and radii on all sides and toothed spikes which are used in combination with spacer components. The cages and spacer can be locked together into a variety of geometric configurations to fit each individual patient's pathology. The toothed spikes of the rounded rectangular and rectangular cages engage with the superior and inferior end plates of the neighboring vertebral bodies to resist rotation and migration. A single construct is sufficient to be used at all spinal levels and pathologies.

§ 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)

C. Substantial Equivalence
The technological characteristics of the Theken VU VBR SYSTEM are similar to the following predicate devices:
- CPOD/LPOD VBR System (K032064), manufactured by Theken Surgical LLC and cleared by the 1) FDA on February 20, 2004.
-
- Tetris™ Spinal Implant (K022793), manufactured by SIGNUS Medical LLC and cleared by the FDA on April 8, 2003.
- Synthes Synex "M Spacer System (K003836), manufactured by Synthes Spine Company, L.P. and 3) cleared by the FDA on May 29, 2001.
-
- VBR (K003155), manufactured by Osteotech Inc. and cleared by the FDA on October 16, 2001.
-
- Stackable Cage™ System (K990148), manufactured by DePuy AcroMed, Inc. and cleared by the FDA on September 3, 1999.
- Curved PEEK Tetris™ (K041888), manufactured by SIGNUS Medical LLC and cleared by the FDA 6) on July 9, 2004.
Establishment of equivalence is based on similarities of intended use, design, and physical characteristics. All implants are used to treat the same conditions, have essentially the same precautions and contradictions for use, and have equivalent potential for complications for the risk of use. In addition they all represent a basic design concept in terms of safety and effectiveness, and differ only in minor details. Based on the design concept, the use of established well known materials, feature comparisons, mechanical testing, indications for use, pre-production quality assurance planning and engineering analysis (adherence to GLP), Theken Surgical believes that sufficient evidence exists to reasonably conclude that the VU VBR SYSTEM is substantially equivalent to existing legally marketed devices.
