This device is an intervertebral body fusion device (an implant) used as an adjunct to fusion for the treatment of degenerative disc disease. It is a therapeutic device, not a diagnostic one.
No
The device description clearly states it is comprised of a PET mesh bag, which is a physical hardware component.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening.
- Device Description: The Spineology Interbody Fusion System (SIFS) is a physical implant (a PET mesh bag) designed to be placed inside the body during surgery to aid in spinal fusion.
- Intended Use: The intended use is to provide structural support and contain bone graft within the intervertebral disc space to promote fusion. This is a surgical intervention, not a diagnostic test performed on a specimen outside the body.
- Lack of IVD Characteristics: The description does not mention any analysis of biological samples, reagents, or diagnostic assays, which are hallmarks of IVD devices.
The SIFS is a surgical implant used in a therapeutic procedure, not a diagnostic device.

Radiographic Assessment:
Fusion was assessed by independent radiologists at the 12-month time point, and again at 24 months for those subjects who had not fused. At 12 months, "My subjects were evaluated for
fusion. (D) (4) designation of "fused" at 12 months, and one of those (b)(4)subjects was not imaged due to pregnancy. At the 24-month time point, (b) (4) of those (b) (4)subjects were determined to be fused. The (010) patient that was determined not fused was the subject who was pregnant at the 12-month time point. Overall, at 24 months, the fusion rate for all evaluated subjects is 99.0% (b) (4) when considering the 12- and 24-month fusion assessments, and similarly, 99.0% (b) (4) when considering subjects who were evaluated at 24 months. The fusion status is summarized in Table 8 below.

Safety Assessment
A Clinical Events Committee (CEC) was utilized for the study to mitigate reporting bias of safety-related events. Each event was evaluated for applicability (event versus observation), relatedness to the study (study-related event versus non study-related event), and additional classifications of seriousness (serious adverse events, unanticipated adverse device effects, neither) and severity (mild, moderate, severe).
One hundred and twenty-five (125) events were reported in this study of which 6 were nonevents. The events are classified in Table 13 below:

Neurological assessment was performed at baseline, prior-to-discharge from the hospital, and at each study evaluation thereafter through 24 months. At each timepoint, subjects were evaluated to ascertain if their neurological status (reflexes, sensory, and strength) was improved, maintained, or worsened when compared to pre-op. Most subjects were reported to have improved or maintained their neurological status, with 5.3% (5/95), 2.1% (2/96) and 1.0% (1/96) of subjects reported to have worsened in their reflex, sensory and strength neurological

Overall Conclusion:
As stated earlier, this prospective, single arm, multi-center study was designed to meet a predetermined performance goal at 24 months which was based on a previously conducted prospective, randomized, multi-center study on the same device. The performance goal was based on four (4) parameters: pain (evaluated by VAS), function (evaluated by ODI, fusion
19
(evaluated by imaging), and safety (evaluated by adverse events). These identified parameters are also in-line with the FDA Guidance Document, Preparation and Review of Investigational Device Exemption Avolications (IDEs) for Total Artificial Discs. (D) (4) of the subjects (85.4%) had at least a 20 mm improvement in VAS pain score. (b) (4) of the (b) (4) subjects (81.3%) had at least a 15-point improvement of the (b) (4) in ODI score. (b) (4) subjects (99.0%) achieved a fusion. (b) (4) = of the (b) (4) subjects (92.9%) for freedom from device-related Serious Adverse Events and secondary surgical interventions at the index level. The results are summarized in the table below:
Table 16: Overall
