Intended Use

The Epley Omniax is intended to assist in the diagnosis and treatment of balance disorders and vertigo, including benign paroxysmal positional vertigo.

Device Story

Epley Omniax is a multi-axial positional chair system for diagnosing and treating balance disorders and vertigo. System includes chair unit with restraints, videonystagmography (VNG) goggles with camera, and operator pedestal containing computer, monitor, and power distribution. Operator selects movement sequences via software interface; chair rotates on two axes to position patient relative to gravity. Goggles capture eye movements; system records and displays eye and chair movements on operator computer. Used in clinical settings by medical professionals. Output allows operator to assess nystagmus, select treatment maneuvers, and review recordings. Benefits include automated, precise patient positioning compared to manual manipulation, facilitating diagnosis and treatment of conditions like BPPV.

Clinical Evidence

Clinical studies compared Omniax to standard of care (VNG goggles plus manual physician maneuvers). Diagnostic study (n=27) and treatment study (n=37) reported findings equivalent to standard of care. No complications or adverse events reported.

Technological Characteristics

Multi-axial positional chair with two-axis rotation. Includes VNG goggles, computer interface, and operator pedestal. Safety features: emergency stop, override buttons, pinch guards, manual crank. Connectivity: wireless communication between chair and computer. Standards: IEC 60601-1, IEC 60601-1-2 (electrical safety/EMC), ANSI Z136.1 (goggles).

Indications for Use

Indicated for patients with balance disorders and vertigo, including benign paroxysmal positional vertigo (BPPV).

Device name:

Epley Omniax™ Proprietary name: Common or usual name: Multi-axial chair Classification name: Vestibular analysis apparatus, LXV, unclassified and Nystagmograph, GWN, 882.1460, Class II.

Legally marketed device for substantial equivalence comparison:

K964325 - VisualEyes from MicroMedical Technologies, Inc.

K863424 - Computer Eye Tracking System/ENG Exam Chair/Table from MicroMedical Technologies, Inc.

K922037 - System 2000 from MicroMedical Technologies, Inc.

K070085 - Balance Rehabilitation Unit from Medicaa, S.A.

#### Description of the device:

The Epley Omniax is a multi-axial positional chair that includes the chair unit and an operator's pedestal. The chair unit includes the chair itself attached to a frame assembly. seat belts and other restraints, and videonystagmography goggles attached to a computer. The operator's pedestal includes the power distribution system, isolation transformer, and computer with monitor, keyboard, and mouse. The two computers communicate wirelessly to transmit and record the chair movements and the eye movements. The device has a number of safety features, such as emergency stop buttons, override buttons, pinch guards, and manual crank in case of power failure.

The patient is strapped into the Omniax, dons goggles with a camera attached, and the operator selects a series of moves utilizing one or both of the axes. The position of the patient in relation to gravity and any eye movements are shown on the operator's computer and recorded for future viewing. Review of these recordings allows the operator to assess conditions and select appropriate treatment.

#### Intended use of device:

The Epley Omniax is intended to assist in the diagnosis and treatment of balance disorders and vertigo, including benign paroxysmal positional vertigo.

{1}------------------------------------------------

## Technological characteristics:

The Epley Omniax has similarities with several predicate devices. It is used similarly to the combination of VisualEyes and either a Chair-Table or the System 2000. The VisualEyes and Chair-Table combination requires medical personnel to manually manipulate the head while viewing nystagmus. The Omniax uses operator-controlled mechanical means through a software interface. The System 2000 is also operatorcontrolled through software. The differences are that the Omniax rotates on two axes, while the System 2000 rotates on one axis. All three products record patient data for immediate use or future review. All three products measure spontaneous nystagmus. The Omniax and the combination product measure positional nystagmus and the Omniax and the System 2000 can be used for rotational testing.

### Testing conducted:

The Omniax has passed all testing to IEC 60601-1 and IEC 60601-1-2. The goggles have been tested and passed ANSI Z136.1.

#### Performance testing:

Studies were presented that support the substantial equivalence of the Omniax to VisualEyes used with a table and manual manipulation by medical professionals. The studies performed provide a comparative analysis of the diagnostic and treatment capabilities of the Omniax versus a common standard of care (SOC) method. This SOC method consisted of the combination of videonystagmograph (VNG) goggles and an examination table used by a physician performing manual maneuvers of the patient. 27 subjects completed and were analyzed for the diagnostic study. 37 subjects completed and were analyzed for the treatment study. Both studies reported findings of equivalence to that of the standard of care. In addition, no complications or adverse events were reported in either study.
