No
The description focuses on standard signal averaging techniques and a software update for improved user interface, with no mention of AI or ML.
No
The device is indicated for recording and displaying human physiological data, primarily for diagnostic and assessment purposes related to auditory and hearing-related disorders, not for treatment or therapy. Although the description mentions "treatment of auditory sensory disorders" under "Device Description", the "Intended Use / Indications for Use" only focuses on diagnosis and assessment.
Yes
The device is indicated to "assist in determining possible auditory and hearing-related disorders" and "assist in the assessment of possible auditory nervous system abnormalities," which are explicit diagnostic purposes.
No
The device description explicitly states that the system includes hardware components (earphone/headphones, EEG electrodes, Navigator Pro module with DSP) in addition to the software. The 510(k) is for a modification to the host computer software, but the overall system is not software-only.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- Device function: The Bio-logic Evoked Potential product family records and displays human physiological data (EEG responses from the scalp) in response to auditory stimuli. It does not analyze specimens taken from the body.
- Intended Use: The intended use is for auditory screening and to assist in determining possible auditory and hearing-related disorders by recording brain responses. This is a physiological measurement, not an in vitro test.
The device is a diagnostic tool, but it operates by measuring physiological responses directly from the patient, not by analyzing samples in a laboratory setting.
N/A
Intended Use / Indications for Use
The Bio-logic Evoked Potential (EP) product family is indicated for use in the recording and display of human physiological data, for auditory screening purposes and to assist in determining possible auditory and hearing-related disorders. Auditory stimuli are presented to the patient's ear through an earphone or headphones, and the corresponding Auditory Brainstem Responses (ABR) from the patient are recorded using EEG electrodes placed on the scalp. Standard ABR testing is most used clinically for 2 reasons: (1) to predict behavioral audiometric thresholds, and (2) as an audiological testing tool to assist in the assessment of possible auditory nervous system abnormalities.
The Bio-logic Navigator Pro EP System can be used for patients of all ages, from children to adults, including infants and geriatric patients. The use of the Bio-logic EP family of products is to be performed under the prescription and supervision of a physician or other trained health care professional.

Device Description
The Bio-logic Auditory Evoked Potential (AEP) family of products is used for the recording, display, computation, and manipulation of human physiological data, for auditory screening purposes and to provide assistance in the neurological assessment and treatment of auditory sensory disorders. The predicate device referenced above is the latest in a series of complete systems of this type marketed by Bio-logic.
The Navigator Pro Evoked Potential Predicate Device performs Auditory Brainstem Response (ABR) recording functions with two channels of simultaneous data recording. The software for the Navigator Pro implements the standard ABR functions common to most similar systems on the market for many years.
The standard ABR test works on the basis of repeating a stimulus-response cycle. An auditory stimulation (click, tone, etc.) is presented to the patient through the use of an earphone or headphones. The EEG response from the brain is read through the use of one or more scalp electrodes placed on the patient. The response time of interest is approximately from 1 - 20 milliseconds following the stimulus. The response voltage readings for this time period are amplified, digitized and stored in the AEP system computer's memory. The stimulation is then repeated, the EEG response is read again, and this cycle is repeated many times . Each time the response is read, it is averaged together with all previous responses. The final data record is the result of averaging several thousand (usually 2000-3000) responses. This averaging process is necessary because the ABR signal is very small, much lower in voltage than the surrounding EEG "noise" present in the recording. The noise is averaged out over the many readings, because the noise will have a very low average net value. The result from the averaging process will be the signal.

The noise is averaged out over the many readings, because the noise will have a very low average net value. The result from the averaging process will be the signal.
The reason for this 510(k) is that the software for the host computer (PC) in the Evoked Potential system has been modified. The host computer software for the Predicate Device is DOS-based, whereas the host software for this modified Bio-logic AEP program is WINDOWS-based. The WINDOWS program has the same features and functionality as that of the predicate device, but with improved user interfaces and overall ease-of-use. The functions of the hardware are the same as those of the Predicate Device (Navigator Pro) hardware. The host computer software for control of the hardware has the same functionality as that of the DOS-based Predicate Device software. Direct hardware control of all Navigator Pro functions is provided from the Digital Signal Processor (DSP) and its program code located inside the Navigator Pro module, instead of directly from the host computer program. (There are no changes to the DSP program code in the Navigator Pro module as a result of this host computer software modification.) By distributing the hardware-specific functions to the DSP, the Windows-based host computer program has fewer real-time demands, and performance and reliability are improved. Together, the hardware and software implement the same functionality and perform the same intended use as the Predicate Device, but with improved ease-ofuse and flexibility for the user.

INTENDED USE:
The Bio-logic Evoked Potential (EP) product family is indicated for use in the recording and displav of human physiological data, for auditory screening purposes and to assist in determining possible auditory and hearing-related disorders. Auditory stimuli are presented to the patient's ear through an earphone or headphones, and the corresponding Auditory Brainstem Responses (ABR) from the patient are recorded using EEG electrodes placed on the scalp. Standard ABR testing is most used clinically for 2 reasons: (1) to predict behavioral audiometric thresholds, and (2) as an audiological testing tool to assist in the assessment of possible auditory nervous system abnormalities.
The Bio-logic Navigator Pro EP System can be used for patients of all ages, from children to adults, including infants and geriatric patients. The use of the Bio-logic EP family of products is to be performed under the prescription and supervision of a physician or other trained health care professional.
SAFETY AND EFFECTIVENESS SUMMARY
To establish the safety and effectiveness of this modification to the Bio-logic Evoked Potential software, the modification was designed and incorporated into the product in accordance with the Bio-logic internal Product Development procedures, which are intended to meet ISO-9001, ISO-13485 and FDA QSR Design Control specifications. A detailed Hazard/Risk analysis for the EP family of products was performed using the Fault Tree analysis (FTA) approach, and a detailed Risk Assessment for the modified Evoked Potential product was written in accordance with ISO-14971, the International Standard: Application of Risk Management to Medical Devices.
As with the Predicate Device, the modified software does not make any final decisions that result in any automatic forms of diagnosis or treatment. All program "recommendations" are subject to review by a qualified health care professional, and may be modified, overridden or deleted as determined by the qualified user. The program provides functions to allow the qualified user to review all raw data collected and perform other data analysis to suit his or her requirements.
The chart on the following page provides a summary comparison of the technological characteristics of the modified Evoked Potential device relative to the predicate Navigator Pro device. This is to demonstrate that this Modification to Bio-logic Evoked Potential for Navigator Pro has no significant differences which would adversely affect product safety and effectiveness.
