The Eclipse with VEMP (Vestibular Evoked Myogenic Potential) is intended for vestibular evoked myogenic potential testing to assist in the assessment of vestibular function. The target population for Eclipse with VEMP includes patients aged from 8 years and up. The device is to be used only by qualified medical personnel with prior knowledge of the medical and scientific facts underlying the procedure.

The Eclipse with VEMP is audiometric equipment intended to perform various Otoacoustic Emissions (OAEs) and Auditory Evoked Potential evaluations. The Eclipse is operated solely from PC based software modules. The Eclipse platform performs the physical measurements. The protocols are created in the software modules. The Eclipse consists of a hardware platform, a preamplifier, stimulation transducers and recording electrodes. VEMP evaluations are tests of the vestibular portion of the inner ear and acoustic nerve, evoked with an auditory stimulation. The evoked response results in a potential recorded from the sternocleidomastoid (neck) muscles or the inferior oblique (eye) muscles. VEMP is not a test of the neck or eye musculature directly; the clinician is interested in the vestibular anatomy which triggers the response. The cervical Vestibular Evoked Myogenic Potential (cVEMP) is an evoked potential measured from the sternocleidomastiod (SCM) muscle and the ocular VEMP (oVEMP) is an evoked potential measured from the inferior oblique muscle. Both tests are used to assess the otolith organs (saccule and utricle) of the vestibular system and their afferent pathways and assist medical practitioners in the diagnosis of various balance disorders. Summary: VEMP is Auditory Evoked Potentials like ABR obtained using any commercially available EP system. The addition of the VEMP module to Eclipse will make it possible for clinicians to conduct VEMP tests while using EMG (electromyography) monitoring and scaling. The VEMP function of the Eclipse with VEMP does not make a diagnosis. It only assists the medical professional.

There are no difference in any settings or parameters in these default tests in any of the devices. The clinical validation tests showed that each test was performed in exactly the same manner and resulted in similar findings when comparing VE525 to the predicate devices.

The Interacoustics AT235 Impedance Audiometer is an electroacoustic test instrument that produces controlled levels of test tones and signals intended for use in conducting diagnostic hearing evaluations and assisting in the diagnosis of possible otologic disorders. It features tympanometry, acoustic reflex and air conduction audiometry.

AT235 is an auditory impedance analyser. The device is intended to change the air pressure in the external auditory canal and measure and graph the mobility characteristics of the tympanic membrane to evaluate the functional condition of the middle ear. The device is used to determine abnormalities in the mobility of the tympanic membrane due to stiffness, flaccidity, or the presence of middle ear pathologies. The device is also used to measure the acoustic reflex threshold which occurs due to contractions of the stapedial muscle following exposure to a strong stimulus. This test allow to assess between central and peripheral pathologies and to identify where the patients uncomfortable loudness level may reside. The uncomfortable loudness level is useful when providing rehabilitative amplification methods and determining the correct management process for the patient. The AT235 also includes basic audiometry functions. The instrument is software controlled. The software controls the probe (tone and pressure) stimuli, measures the result and presents the result on a built in display. All functions are set and interpreted by the operator (There are no interpretations of results in the device). The technological characteristics are substantially equivalent with predicate device. All technological characteristics are in compliance with the consensus standard ANSI S3.39 for auditory impedance testers

The EyeSeeCam vHIT is designed to provide information on the performance of the vestibular ocular reflex (VOR) by providing objective measures of eye-velocity response to head-velocity stimulus, showing the VOR gain in the plane of rotation of the head.

The EyeSeeCam vHIT system consists of a head mounted goggle/mask, a camera unit with calibration laser and a software application running on a standard PC. The vHIT goggle generally has one camera (monocular) fixed at the top side(s) of the mask. The camera is held in place mechanically with a spherical ball-and-socket joint. The vHIT goggle has support for camera position-for the left and for the right eye. Therefore the camera is interchangeable between the left and right eyes. The vHIT goggle supports the camera that is used to record the eye images. This constitutes the major component of the vHIT system. The USB camera uses infrared light (IR), which is not visible to the naked eye. The IR illumination enables sessions to be performed in complete darkness. The vHIT goggle has dichroic mirrors that allow visible light to pass through and infra red light to be reflected towards the cameras. A calibration laser is placed in the center of the goggle. This is used for camera / pupil calibration before testing. The complete system is operated from a standard PC/Laptop via a standard USB connection. The PC application software controls the camera recordings and shows the results of the tests. EyeSeeCam utilizes an inertial measurement unit (IMU) which is an accelerometer and gyroscope combined. The IMU is contained inside the camera unit. The camera housing is attached to a light weight goggle. The camera records eye movements and the IMU records an electronic waveform that is proportional to head angular velocity (deg/sec).
