No
The document describes a mechanical screw and its components, with no mention of software, algorithms, or any technology related to AI or ML.

No
The device is a compression screw used for bone fixation and reconstruction, which are structural and mechanical functions, not therapeutic as it does not treat disease or restore health directly.

No
The device is a compression screw used for bone fixation and reconstruction, which is a therapeutic rather than a diagnostic function.

No

The device description clearly outlines physical hardware components (screws and compression caps made of stainless steel) and their manufacturing details, indicating it is a physical medical device, not software-only.

Based on the provided information, the CHARLOTTE™ High-Demand Compression Screw is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • IVD devices are used to examine specimens derived from the human body. This device is a surgical implant used for fixing bone fractures and reconstruction.
  • The intended use clearly describes a surgical procedure. The indications for use involve fixing bone fragments, managing fractures, performing arthrodesis, and treating diastasis. These are all surgical interventions performed directly on the patient's body.
  • The device description details a physical implant. It describes screws and compression caps made of stainless steel, designed for insertion into bone.

Therefore, the CHARLOTTE™ High-Demand Compression Screw is a surgical implant, not an in vitro diagnostic device.

§ 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 Mr. Reed:

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 commence 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. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
