#### 6. Intended Use and Indications for Use of the Subject Device

Disposable Non-invasive EEG Sensor is applied directly to the patient's skin to enable recordings of electrophysiological (such as EEG) signals.

#### 7. Device Description

Disposable Non-invasive EEG Sensor is a sensor assembly with pre-gelled electroencephalogram (EEG) electrodes. The Sensor is applied to the skin of the patient to record electrophysiological (such as EEG) signals. It is a low impedance, single patient use, non-sterile disposable electrode sensor that is designed for application to areas including forehead, temporal, above eyebrow and mastoid process. The Sensor is designed to provide ease of use and electrode placement accuracy. It is used in conjunction with a monitor with an EEG module.

The sensor design is constructed using FPC (Flexible Printed Circuit Board) and medical foam. Place the foam plate and conductive gel on the FPC board. The bottom of the foam is covered with medical grade pressure sensitive adhesive for skin adhesion. A printed circuit board, which is part of the FPC board and printed with conductive silver chloride, is pasted on the other side of the foam. The

{5}------------------------------------------------

flexible foam wrapped with conductive gel is used to contact the skin. When the flexible foam contacts the skin, the conductive gel will connect the skin with the FPC board to form a conductive bridge. The silver/silver chloride circuit provides signal continuity from each electrode to the monitor. The FPC board is attached to site like forehead and transmits EEG signals.

Note 1

The number of 4/6 electrodes is the same as Predicate #1.

The number of 3 electrodes is the same as Predicate #2.

The number of 5 electrodes falls within the possible customizable number of electrodes of Predicate #1 (between 4 to 6 electrodes).

The difference of the number of electrodes of the proposed device does not affect its safe and effective usage in monitoring of EEG signals. The device has been tested in accordance with electrical safety and performance tests, and the tests passed. Thus, such a difference among the proposed device and the predicate devices does not affect substantial equivalence.

### Note 2

Although the description of application sites of the proposed device are different from those of the predicate devices, the application sites are actually the same among three devices regarding frontal area. The actual use and application of the predicate devices on frontal area involve forehead and above eyebrow, with the description of the proposed device being more detailed. Regarding the additional application site of mastoid process that the proposed device specifies, it does not raise different questions of safety and effectiveness as the device meets safety and performance requirements.

#### Note 3

Although the usage time and material of the two predicate devices are not publicly available in the 510(k) Database, biocompatibility tests have been performed on the proposed device and the tests passed. Therefore, such a difference does not affect substantial equivalence among the proposed device and two predicate devices.

#### Note 4

The proposed device and the predicate devices all comply with electrical safety standards and performance standards. Therefore, absence of the information concerning Operation and Storage Environment of the two predicate devices does not raise questions of safety and effectiveness for the proposed device.

#### Note 5

Both the proposed device and the Predicate Device #2 performed electrical safety tests in accordance with 60601-1 standards.. Thus, the difference does not raise different questions of safety and effectiveness. The two devices are substantially equivalent regarding electrical safety.

#### 9. Non-clinical Test

The safety and effectiveness of the subject device are demonstrated through testing following ANSI/AAMI ES60601-1 General requirements for basic safety and essential performance and ANSI/AAMI EC12: 2000/(R)2015 Disposable ECG Electrodes. The results of bench testing provides reasonable assurance that the proposed device has been designed and validated to assure conformance to the requirements for its indication for use. Package integrity and functional performance testing were completed on the subject device following Accelerated aging test to support the proposed shelf life.
