No
The summary describes a system for collecting and presenting data related to eye movements and vestibular responses. It explicitly states that the device provides no diagnoses or diagnostic recommendations, and the analysis is performed by trained medical personnel. There is no mention of AI, ML, or any algorithms that would learn from data or make predictions. The software mentioned (VEST and I-Portal) appears to be for data acquisition, processing, and presentation, not for AI/ML analysis.
No
The device is described as a diagnostic tool used to measure, record, or visually display involuntary eye movements for interpretation by qualified medical personnel trained in vestibular diagnostic testing. It "provides no diagnoses nor does it provide diagnostic recommendations" and is not indicated for treating or curing any condition.
Yes
The "Intended Use / Indications for Use" states that the devices are "used in vestibular and neuro-otologic diagnostic testing." The "Device Description" also specifies its use "as a diagnostic tool to assist trained physicians in their analysis of vestibular disorders". Although it states that the device provides no diagnoses or diagnostic recommendations, it is used for diagnostic testing and provides data for interpretation by qualified medical personnel, which qualifies it as a diagnostic device.
No
The device description explicitly mentions hardware components like a rotational chair, optokinetics optical stimulus, Pursuit Tracker laser target generator, and a test enclosure, in addition to the software.
Based on the provided text, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze specimens from the human body. The provided text describes a device that monitors and records eye movements in response to stimuli. It does not mention the analysis of any biological specimens like blood, urine, or tissue.
- The device's function is described as a nystagmograph. The definition provided from 21 CFR 882.1460 clearly states it's a device used to measure, record, or visually display involuntary movements of the eyeball. This is a physiological measurement, not an in vitro analysis.
- The intended use focuses on providing stimuli and monitoring patient response. The device provides motion profiles and visual cues and then monitors eye movements (nystagmus) as a response. This is a direct interaction with the patient's physiological response, not an analysis of a sample taken from the patient.
Therefore, the I-Portal® Neuro Otologic Test Center (NOTC), I-Portal® Video-Nystagmography System (VNG), and I-Portal® Video Oculography (VOG) System, as described, are not IVDs. They are devices used for physiological measurement and diagnostic testing based on patient responses to stimuli.

Intended Use / Indications for Use
I-Portal® Neuro Otologic Test Center (NOTC) is a rotary chair system used in vestibular and neuro-otologic diagnostic testing. The NOTC provides stimuli to a patient through motion profiles and/or visual cues, monitors the patient's response, and presents the data for interpretation by qualified medical personnel trained in vestibular diagnostic testing. This device provides no diagnoses nor does it provide diagnostic recommendations.
I-Portal® Video-Nystagmography System (VNG) is used in vestibular and neuro otologic diagnostic testing. The VNG provides stimuli to a patient through visual cues, monitors the patient's response, and presents the data for interpretation by qualified medical personnel trained in vestibular diagnostic testing. This device provides no diagnoses nor does it provide diagnostic recommendations.
I-Portal® Video Oculography (VOG) System is used to monitor and record eye movements from various stimuli used in vestibular diagnostic testing. The system measures and records horizontal, vertical, and torsional eve movements, as well as pupil area. It is used in conjunction with various stimuli (rotary chair, manual (done by clinician) positional maneuvers, caloric tests, external stimulus) to detect and record nystagmus and eye tracings for interpretation by qualified medical personnel trained in vestibular diagnostic testing. This device provides no diagnoses nor does it provide diagnostic recommendations.

Device Description
The I-Portal device functions as a nystagmograph, defined by 21 CFR 882.1460 as "a device used to measure, record, or visually display the involuntary movements (nystagmus) of the eyeball." Through its nystagmograph functionality, the device is indicated for use as a diagnostic tool to assist trained physicians in their analysis of vestibular disorders, which requires the separation of central and peripheral nervous system deficits. The I-Portal device is used in an institutional environment on the order of a clinician.
To achieve safe and effective clinical operation, the I-Portal devices use an extensive battery of tests within a family of products: the I-Portal NOTC, the VNG, and the VOG.
The I-Portal NOTC features a rotational chair, the optokinetics (OKN) optical stimulus, the Pursuit Tracker (PT) laser target generator, an I-Portal and VEST software, and a test enclosure equipped with a communication system. Through the use of these elements and the VEST™ analysis software, the physician is able to schedule a set of tests designed to help isolate, identify and understand oculomotor, neurologic and vestibular functions and related possible disorders.
The I-Portal VNG offers a subset of the NOTC tests and different vestibular tests through a device with a smaller physical footprint. The VNG has many of the same elements used in the NOTC configuration: OKN optical stimulus, PT laser target generator, VOG, I-Portal and VEST software platforms. However, unlike the NOTC. it does not have either the rotational chair or the enclosure & communication system, but the VNG can collect and analyze data from caloric and position tests. The VNG configuration is typically used in smaller clinics or conditions requiring a smaller sized device or some mobility.
The third NKI I-Portal configuration is a digital eve tracking system - the I-Portal VOG. The VOG is incorporated within the NOTC and VNG configurations; however, the VOG can be used as a stand-alone product with the VEST and I-Portal software, but offering a subset of the tests afforded by either the NOTC or VNG.
