No
The summary describes standard titanium bone plates and screws for rigid fixation, with no mention of AI, ML, image processing, or any other technology typically associated with AI/ML in medical devices.

No
The device is described as titanium bone plates and screws for rigid fixation of cranio, facial, and neurological bone. It serves as an implant for structural support and fixation, rather than providing direct therapeutic action to treat a disease or condition.

No
Explanation: The device is described as rigid fixation for cranio, facial, and neurological bone, and consists of titanium bone plates and screws for surgical procedures. This functionality points to a therapeutic or supportive device, not one designed to diagnose a condition.

No

The device description explicitly states it is comprised of "titanium bone plates and screws," which are physical hardware components, not software.

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

Here's why:

  • Intended Use: The intended use is "Rigid fixation of cranio, facial and neurological bone." This describes a surgical procedure performed directly on the patient's body.
  • Device Description: The device is described as "titanium bone plates and screws." These are physical implants used in surgery.
  • Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing samples (blood, urine, tissue, etc.)
    • Providing information about a patient's health status based on sample analysis
    • Reagents, calibrators, or controls

IVDs are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device is a surgical implant used for structural support.
