The description focuses on standard signal processing techniques (amplification, filtering, ADC conversion, data processing) and does not mention AI or ML. The performance studies validate specific signal processing methods (Bayesian weighting, low pass filtering) and software compatibility, not AI/ML model performance.
No
The device is described as an evaluation, documentation, and diagnostic tool for ear disorders, not one that provides therapy or treatment.
Yes
The "Intended Use / Indications for Use" section explicitly states that the systems "are intended to assist in the evaluation, documentation and diagnosis of ear disorders on human beings."
No
The device description explicitly mentions hardware components like skin electrodes, a preamplifier, and an Analog to Digital Converter (ADC) as integral parts of the system for data acquisition and processing.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens, including blood, tissue, and urine, derived from the human body, solely or principally for the purpose of providing information concerning a physiological or pathological state, or a congenital abnormality, or to determine the safety and compatibility of transfused blood, or to monitor therapeutic measures.
- Device Function: The Interacoustics EP and TEOAE systems measure physiological responses (auditory brainstem responses and otoacoustic emissions) directly from the patient's body using surface electrodes and probes. They do not analyze specimens in vitro.
- Intended Use: The intended use is to assist in the evaluation, documentation, and diagnosis of ear disorders by measuring these physiological responses. This is a direct measurement of bodily function, not an analysis of a sample outside the body.
Therefore, the device falls under the category of a non-IVD medical device that measures physiological signals.
N/A
Intended Use / Indications for Use
The Interacoustics EP systems, EP15 and EP25, are intended to assist in the evaluation, documentation and diagnosis of ear disorders on human beings. EP15/25 is a 2 channel ABR and the automatic recording of ABR waveforms makes it well suited for waveform based screening and the manual programmability options allow for comprehensive clinical use ranging from frequency specific threshold test to operating room applications and cochlear implant tests. The EP15 is a basic unit allowing only recording of the Auditory Brainstem Response (ABR), while the EP25 allows recording of the ABR and earlier and later potentials.
The Interacoustics TEOAE25 system is intended for determining Cochlear function using Transient Evoked Otoaccoustic Emission click stimuli.

Device Description
The EP15 and EP25 systems measure auditory brainstem responses picked up by skin electrodes and amplified by a pre amplifier. The data acquisition of the ABR recordings takes place from the surface electrodes mounted at specific recording points on the patient. The analogue ABR recordings are amplified in the external preamplifier connected to the electrodes. The amplified analogue ABR recordings are converted into a digital signal in the ADC (Analog to Digital Converter) inside the Eclipse. The digital ABR recordings undergo data processing handled by the PC to improve the ABR-recordings. The ABR-recordings are displayed on the monitor for the operator, for further examination and diagnosis. All ABR recordings are stored on the Laptop / Desktop computer hard drive for later examination and diagnosis.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The usefulness of the EABR protocol setup has been validated with a positive result. The correct implementation of the new stimuli, i.e. chirp, NB chirp and click from wave file, have been verified through bench testing which provided the expected results. The generated electrical output was consistent with the mathematically predicted output. The correct implementation of the Bayesian weighting and low pass filtering has also been verified through bench testing and the results were as predicted. The EP15/EP25's ability to run under windows Vista® has also been tested and no abnormal behavior was detected.
