No
The description focuses on standard evoked response recording technology and does not mention AI or ML.
No
The device is described as an "assessment tool" to "record evoked responses" for diagnostic purposes, not for treating a condition.
Yes
The device is intended to "record evoked responses upon presentation of sensory stimuli to the facial nerve" and is indicated for use "as an assessment tool to supplement the case history information, physical examination, imaging studies, and/or other sensory evaluations conducted by or on the order of the physician." This functionality clearly aligns with diagnostic purposes, supporting the physician in understanding a patient's condition.
No
The device description explicitly states that the ENoG Protocol is a feature of the Navigator Pro with AEP Software Evoked Response System, which is a Windows® based software application for use with the Navigator Pro hardware platform. It also describes the use of stimulus electrodes and other hardware components for recording the evoked response. This indicates it is not a software-only device.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The description clearly states that the device records "evoked responses (i.e., electrical potentials) upon the presentation of sensory stimuli to the facial nerve." This involves applying stimuli to the patient's body and measuring the resulting electrical activity.
- No Sample Analysis: There is no mention of analyzing samples taken from the patient's body. The measurements are taken directly from the patient's electrical responses.
Therefore, this device falls under the category of an in vivo diagnostic device, as it performs measurements directly on a living organism.

Device Description
The ENoG Protocol is a feature of the Navigator Pro with AEP Software Evoked Response System; a Windows® based software application for use with the Navigator Pro hardware platform for the recording of evoked responses (i.e., electrical potentials) upon the presentation of sensory stimuli.
The ENoG Protocol works on the basis of a repeating stimulus-response cycle. It is a convenience feature developed for the user to quickly set up testing for Electroneuronography evaluation of the facial nerves. The protocol utilizes the existing technology of the evoked response somatosensory function of the software. The evoked response from the patient is recorded through the use stimulus electrodes positioned near the mastoid, a cathode behind the earlobe, and an anode in front of the earlobe with the forehead as the ground.
