The summary describes a mechanical implant (vertebral body replacement) and its intended use, without any mention of AI, ML, image processing, or data analysis capabilities.
Yes
The device is indicated for replacing a portion of a diseased vertebral body due to tumors, treating fractures, decompressing the spinal cord, and restoring vertebral height, all of which are therapeutic interventions.
No
The device is described as a vertebral body replacement (VBR) implant used for structural support in the spine, not for diagnosing conditions.
No
The device description explicitly states it is a "single piece titanium VBR" and includes an "insertion tool," indicating it is a physical implant and associated hardware, not software.
Based on the provided information, the Stansion Matrix is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a surgical implant used to replace a portion of a vertebral body in the spine. This is a therapeutic device, not a diagnostic one.
- Device Description: The description details a titanium implant designed for surgical implantation.
- Lack of Diagnostic Elements: There is no mention of the device being used to test samples (blood, tissue, etc.) or to provide information about a patient's health status through in vitro analysis.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. The Stansion Matrix does not fit this description.
N/A
Intended Use / Indications for Use
The Stansion Matrix is indicated for use in the thoracolumbar spine (i.e., T1 to L5) to replace a portion of a diseased vertebral body that is resected or excised for the treatment of tumors, where the defect is contained within a single vertebral body, in order to achieve anterior decompression of the spinal cord and neural tissues, and to restore the height of a collapsed vertebral body. The device is also indicated for treating fractures of the thoracic and lumbar spine. The Stansion Matrix is designed to restore the biomechanical integrity of the anterior, middle, and posterior spinal column even in the absence of fusion for a prolonged period of time. The device is intended for use with supplemental rigid posterior pedicle screw fixation.

Device Description
The device is a single piece titanium VBR that is open on all sides to maximize bone ingrowth. It is available in three sizes. The device is implanted via the posterior approach, according to similar methods as the predicates. An insertion tool is provided with the device to facilitate its implantation.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The technological characteristics of the Stansion Matrix are very similar to the predicates with respect to shape, sizes, materials, and method of use. Like several of the predicates, the Stansion Matrix is made of titanium alloy. The minor differences in the design and the range of available sizes compared to the predicates do not raise any new questions of safety or effectiveness.
The Stansion Matrix has the same intended use and very similar indications for use to the predicate devices. The Stansion Matrix also is similar to the predicates with respect to its shape, size range, materials, and method of use. Any minor differences in technological features do not raise new issues of safety or effectiveness, as confirmed by performance testing. Therefore, the Stansion Matrix is substantially equivalent to the predicates.

§ 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.

Summary Basis for the Finding of Substantial Equivalence
The Stansion Matrix has the same intended use and very similar indications for use to the predicate devices. The Stansion Matrix also is similar to the predicates with respect to its shape, size range, materials, and method of use. Any minor differences in technological features do not raise new issues of safety or effectiveness, as confirmed by performance testing. Therefore, the Stansion Matrix is substantially equivalent to the predicates.
