No
The device description and performance studies focus on the physical properties and light emission capabilities of a flexible fiber optic instrument, with no mention of AI or ML algorithms for image processing, data analysis, or decision support.

No.
The device's intended use is to "locate, illuminate within, and transilluminate across nasal and sinus structures," which is diagnostic or assistive in nature, not therapeutic. It helps visualize structures but does not treat any condition.

No

Explanation: The device's intended use is to "locate, illuminate within, and transilluminate across nasal and sinus structures." This describes an assistive function for visualization during a procedure, not a diagnostic function that aims to identify a disease, condition, or provide a clinical assessment.

No

The device description clearly outlines physical components (flexible instrument, fiber, sheath, light post, adapter, cannula) and mentions design verification testing related to hardware compatibility (LED light sources). There is no mention of software as a component or function of the device.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples such as blood, urine, or tissue that have been taken from the human body to detect diseases or other conditions.
  • Device Function: The description clearly states the device's intended use is to "locate, illuminate within, and transilluminate across nasal and sinus structures." This is a direct interaction with the patient's body for visualization purposes.
  • No Sample Analysis: There is no mention of analyzing any biological samples taken from the patient. The device is used for direct visualization of anatomical structures.

Therefore, based on the provided information, the PathAssist Light Fiber is a medical device used for illumination and visualization within the body, not an in vitro diagnostic device.
