Intended Use
The InFix System is a vertebral body replacement device intended for use in the thoracic and/or thoracolumbar spine (T3 - L5) to replace a collapsed, damaged or unstable vertebral body resected or excised (i.e., partial or total vertebrectomy procedures) due to tumor or trauma (i.e., fracture). InFix 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. The InFix is intended to be used with bone graft.
Device Description
InFix® is manufactured from implantable grade titanium 6AL-4V alloy that conforms to ASTM F-136, and is available in various sizes and dimensions. The device is comprised of two opposing endplates supported by vertical members or "struts" that can be varied in height such that the surgeon can fix the vertebrae in a proper anatomical alignment and lordosis. Each of the struts includes a load-sharing mechanism that allows a limited amount of strain across the fusion mass while supporting the load bearing surfaces. An Ultra High Molecular Weight Polyethylene (UHMWPE) end cap may be placed inside the device prior to packing of bone graft to effectively block the posterior opening in the device and contain the material inside. Holes in the titanium endplates provide space for bone in-growth while angled spikes (teeth) penetrate the vertebral endplates and provide resistance to rotation and migration.

No
The description focuses on the mechanical design and materials of a vertebral body replacement device. There is no mention of AI or ML in the intended use, device description, or performance studies.

Yes
The device is described as a "vertebral body replacement device intended for use in the thoracic and/or thoracolumbar spine" to replace a damaged vertebral body due to tumor or trauma and restore biomechanical integrity. This functional description aligns with the definition of a therapeutic device designed to treat or alleviate a medical condition.

No

The InFix System is a vertebral body replacement device, which is a therapeutic device designed to replace damaged or unstable vertebral bodies and restore spinal integrity, not to diagnose a condition.

No

The device description explicitly states it is manufactured from titanium and describes physical components like endplates, struts, and spikes, indicating it is a physical implant, not software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly describes a surgical implant for replacing vertebral bodies in the spine due to tumor or trauma. This is a therapeutic and structural device, not a diagnostic test performed on samples outside the body.
  • Device Description: The description details a physical implant made of titanium and UHMWPE, designed to restore biomechanical integrity and facilitate bone fusion. This aligns with a surgical implant, not an IVD.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific analytes, or providing diagnostic information about a patient's condition based on in vitro testing.

Therefore, the InFix System is a surgical implant, not an In Vitro Diagnostic device.

§ 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.
