The device description and performance studies focus on mechanical properties and surgical fixation, with no mention of AI or ML.
Yes
The device is described as a "Sacroiliac Joint Fixation system" and is intended for "fixation of sacroiliac joint disruptions" and "sacroiliac joint fusion," which are therapeutic interventions.
No
The device is described as a "Sacroiliac Joint Fixation system" intended for fixation and fusion of the sacroiliac joint, indicating a therapeutic or surgical purpose rather than a diagnostic one.
No
The device description explicitly states it is a "multiple component system consisting of non-sterile instruments and sterile, cannulated Ø8mm, Ø12mm and Ø14mm Screws" made from titanium alloy. This indicates a hardware-based medical device, not a software-only one.
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 fixation system for the sacroiliac joint. This involves physically implanting a device to stabilize or fuse the joint.
- Device Description: The description details screws made of titanium alloy, designed for surgical implantation and bone collection/grafting. This is consistent with a surgical implant, not a diagnostic test performed on biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific markers, or providing diagnostic information about a patient's condition based on in vitro analysis.
IVD devices are used to examine specimens from the human body to provide information for diagnosis, monitoring, or screening. This device is a therapeutic device used for surgical intervention.

§ 888.3040 Smooth or threaded metallic bone fixation fastener.
(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.

Dear Kim Finch:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrl/cfdocs/cfpmn/pmn.cfm identifies.combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801): medical device reporting of medical device-related adverse events) (21 CFR 803) for
