ICS Dizcovery is used in the assessment of the vestibular-ocularreflex (VOR) and nystagmus by measuring, recording, displaying, and analyzing eye and head movements.

The 1091 ICS Dizcovery is used in the assessment of patients with complaints of a vestibular nature such as dizziness, disequilibrium, and vertigo. The ICS Dizcovery type 1091 does not treat or diagnose the patient; the diagnosis is determined by the credentialed physician.

ICS Dizcovery system is intended to be used by qualified medical personnel. Typical device users are Neurologists, Ears, Nose, and Throat specialists (ENTs), Audiologists, Physical Therapists, and Technicians supervised by one of the four mentioned typical users. Professionals with knowledge of diagnosing balance disorders. Users are assumed to have prior knowledge of the medical and scientific facts underlying the procedures offered by the ICS Dizcovery system.

The intended patient population are children in the age of 10 to 18 and adults in age range from 18 to 99 years with a complaint of dizziness, balance disorder, or vestibular disease.

Device Description

The ICS Dizcovery device is a portable video-oculography (VOG) device. The device shall be indicated for videonystagmography for the assessment of patients with complaints of dizziness, disequilibrium, and vertigo. It provides an assessment of the vestibular-ocular reflex (VOR) and nystagmus by measuring, recording, displaying, and analyzing eye and head movements.

The ICS Dizcovery is a wearable measurement system in the form of goggles, with built-in cameras and a motion sensor that simultaneously track eye- and head-movement, respectively. The goggles have two cameras that collect the eye movement video. The goggle device is connected to a PC with Otosuite Vestibular PC software (through a USB cable). The Otosuite Vestibular software functions by processing the binocular camera data collection. The collection of eye movement data is analysed to eye movement in respect to various stimuli throughout testing.

The ICS Dizcovery system is made up of the following components:

  • A pair of binocular video goggles for testing, controlled through the Otosuite Vestibular PC software
  • Otosuite Vestibular PC software for controlling tests, displaying test data for the various ● tests, reviewing, and printing test results, as well as and managing patients and patient data, users, and test devices.
  • A set of Shadeshift® Vision Denied panels; these panels deny the patients vision throughout ● testing whilst allowing the clinician to continue tracking the eyes in darkness. Vision denied testing is needed throughout the test workflow.
  • . A set of LCD panels; these automatically shift between dark states to facilitate a userfriendly approach to Skew Deviation testing. This removes the need for manually denying vision of each eye separately with the use of a hand or a paddle.
  • A face cushion which inserts into the goggle frame to promote comfort whilst wearing and allow a better fit to face.

The system includes goggles connected to a PC with application software through a USB cable. The patient wears the goggles for testing, the goggles are designed to ensure that they can be secured tightly to the patient's head during testing via a head strap, to prevent them from moving or falling off. A face cushion inserts into the goggle frame so that there is a comfortable fit to the face of the patient and prevention of light from leaking in when testing a patient in vision denied status. The cable connecting to the USB port in the PC has a cable clip to secure to the patient's clothing, this prevents the cable tugging or pulling throughout testing. The patient is presented with a stimulus on a surface (such as a wall) this is projected from the goggles. The patient is asked to track the stimuli with their eyes without moving the head. The goggles have light emitting diodes to light up the eyes and Binocular cameras to record the eye movements. Sliding panels can seal off the patient's eyes from the ambient light when the test requires a darkened environment. An additional set of LCD panels assist in a test that requires movement between dark and light in a short timeframe. These are automatic and driven by the software. The Software will collect the eye movement data in respect to the stimuli generated and analyse the data. A credentialled physician will use this data to make a diagnosis. The device and software include a carry case for mobility and an optional cradle to park the goggles when not in use or between tests.

The ICS Dizcovery system is a non-sterile device intended to be used multiple times per day by the clinician, each appointment would require one use per patient in the above-mentioned clinical environment.

ICS Dizcovery 510(k): K242198

SUBSTANTIAL EQUIVALENCE DISCUSSION:

The subject device has the same intended use, indications for use, clinical users & operating principle as the predicate device. The products are also similar in terms of technological characteristics as both measure record, display, and analyze eye and head movements.

The ICS Dizcovery system represents an upgrade to the predicate ICS Impulse system hardware to improve usability and capability. The ICS Dizcovery system incorporates binocular and monocular video recording and playback, alongside an in-built moveable laser (freedom laser®), compared with the predicate device (ICS Impulse) which incorporates monocular video recording and playback, alongside an in-built static laser. While the ICS Impulse (predicate device) has a single camera that measures and records the movement of the right eye only, the ICS Dizcovery (subject device) has two-camera's that measure and record the movement of both left and right eye simultaneously as well as individually, providing a comprehensive assessment of the left eye as well as the right eye. The movable laser (freedom laser®) utilised for the ICS Dizcovery enables improved usability by allowing the clinician to test using a moving stimulus rather than a static stimulus (as utilized in the predicate device ICS Impulse). This upgraded mechanism prevents the need to move the patients head throughout testing.

The ICS Dizcovery system, including accessories was independently tested to applicable biocompatibility, Safety, EMC, ANSI S3.45 2009 (R2019), Usability, and Software lifecycle standards and demonstrate the subject device is as safe and effective as the predicate device. Reliability testing was also conducted on the ICS Dizcovery device and accessories by a third party.

Design Verification & Validation activities were performed on the subject device and all tests were verified to meet the required acceptance criteria. The performance testing demonstrated that the differences in the design and performance of the subject device do not affect the intended use of the device or raise any new questions on safety and effectiveness of the ICS Dizcovery.

In conclusion, ICS Dizcovery is substantially equivalent to the predicate device ICS Impulse with respect to Intended Use, technological characteristics, and non-clinical Performance data.
