The summary describes a mechanical implant and associated instrumentation for spinal surgery. There is no mention of software, algorithms, data processing, or any other components that would suggest the use of AI or ML. The performance studies focus on mechanical and material properties.
Yes
The device is intended to restore biomechanical integrity, treat degenerative disc disease, and replace vertebral bodies due to tumor or trauma. These are all therapeutic actions.
No
The InFix System is a vertebral body replacement and intervertebral body fusion device. Its intended use is to replace collapsed, damaged, or unstable vertebral bodies or to facilitate spinal fusion, which are therapeutic rather than diagnostic functions.
No
The device description clearly states it is comprised of implants and instrumentation, which are physical components, not software.
Based on the provided text, the InFix® System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- InFix® System Function: The InFix® System is a surgical implant designed to replace or fuse vertebral bodies in the spine. It is a physical device implanted directly into the patient's body.
- Intended Use: The intended use clearly describes a surgical procedure to address structural issues in the spine due to tumor or trauma (VBR) or degenerative disc disease (IBFD). This is a therapeutic intervention, not a diagnostic test performed on a specimen.
- Device Description: The description details the materials, components (endplates, struts, endcap), and dimensions of a physical implant.
- Performance Studies: The performance studies focus on the mechanical properties and biocompatibility of the implant, as well as surgical technique and sterilization. These are relevant to a surgical device, not an IVD.
Therefore, the InFix® System falls under the category of a surgical implant or medical device used for treatment, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
When us as a vertebral body replacement device, the InFix System is intended for use in the thoracic and/or lumbar spine (T3-L5) to replace a collapsed, damaged or unstable vertebral body resected or excised (i.e., partial vertebrectomy procedures) due to tumor or trauma (i.e., fracture). The InFix System 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 implant is intended to be used with bone graft.
When used as an intervertebral body fusion device the InFix System is indicated for use with autogenous bone graft at one or two contiguous levels in the lumbosacral region (L2-S1) in the treatment of degenerative disc disease (DDD) with up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s). DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. Patients with previous non-fusion spinal surgery at involved level may be treated with the device. Patients should be skeletally mature and have had six months of non-operative treatment. When used as an intervertebral body fusion device, the InFix implant is intended to be used with supplemental fixation.
For both of the indications listed above, the InFix implant is intended to be implanted via an open anterior approach.

Device Description
The InFix System is comprised of implants and two configurations of instrumentation. The subject InFix implants are the same design and dimensions as those described in InFix System, VBR submission K031672.
The InFix implant is comprised of two endplates and two struts, which are to be utilized together: with an optional endcap. The InFix System is provided in a range of angles and heights. including the instrumentation (accessories and instruments) necessary to implant the specific system. The current instrumentation is retained in aluminum trays. The new proposed instrumentation is retained in stainless trays.
The InFix implant is manufactured from implantable grade Ti-6AL-4V alloy that conforms to ASTM F-136. The implant is comprised to two opposing Endplates (provided in 0°, 3°, 6° and 9° angles) supported by two vertical Struts available in a range of heights, allowing the surgeon to fix the vertebrae in 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) Endcap may be placed inside the implant prior to packing it with bone graft. The Endcap serves as an optional block of the posterior opening in the implant construct to assist in containing the material inside. Holes in the Endplates provide space for bone in-growth while angled spikes penetrate the vertebral endplates and provide resistance to rotation and migration.
The InFix implant is designed for direct placement between two vertebral bodies. Component sizes and dimensions and the InFix implant depth, width and height are shown below. All dimensions are in millimeters. Strut heights are in 2mm increments.
| Size | InFix Struts | InFix Endplates | |
|---|---|---|---|
| Heights (mm) | Depth (mm) | Width (mm) | |
| Small | 8-14 | 24 | 29 |
| Medium | 8-14 | 26.5 | 32 |
| Large | 8-14 | 29 | 35 |
The InFix implant is assembled and locked in-sity; bone graft is then inserted within the device and up to the anterior rim of the vertebral body.
InFix is implanted using a set of specialized instruments. The subject InFix System specialized instruments (stainless steel trays) are listed in the InFix Anterior Lumbar System Surgical Technique Guide. The current InFix System instruments (aluminum trays) are listed in the InFix Anterior Lumbar Device Surgical Technique Guide. Both instrumentation sets facilitate the insertion and removal of the InFix implants. The InFix implant is provided for single use only.
