Dear Gary J. Syring:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

### Device Description

The eego amplifier is a multi-channel, plastic enclosed EEG amplifier. There are two ranges for the variations of amplifiers (models):

- 1. EE-2xx, and
- 2. EE-4xx.

In total, there are 8 models, as follows:

| Model | EEG<br>Channels<br>(Referential) | Sampling rate configuration<br>(down sampling in API software,<br>internal 32 kHz for all) | Power Source |
|--------|----------------------------------|--------------------------------------------------------------------------------------------|-------------------------------|
| EE-211 | 64 | 2 kHz | Rechargeable battery |
| EE-212 | 32 | 2 kHz | |
| EE-213 | 16 | 2 kHz | |
| EE-221 | 32 | 16 kHz | |
| EE-222 | 64 | 16 kHz | |
| EE-224 | 32 | 16 kHz | |
| EE-411 | 8 | 2 kHz | USB Connection to<br>Computer |
| EE-430 | 8 | 0.5 kHz | |

{4}------------------------------------------------

The EE-411 and EE-430 amplifiers are built using identical components and share identical internal structure, functionality and performance.

The eego amplifier electroencephalography (EEG) input is from commercially available EEG electrodes from the Waveguard™ EEG Cap cleared in K110223.

The eego amplifiers support EEG acquisition and storage by:

- 1. referential DC input channels,
- 2. parallel trigger input channel.

Electrode Impedance values can be measured for all referential electrodes, reference and patient ground electrode. Signal sampling rate and gain are set through the user interface of the Software Development Kit (SDK).

The EE-2XX series of eego amplifier is powered by a built-in, rechargeable battery. The battery provides a minimum of 4 hours of operation time. The amplifier can be applied for data acquisition with the 12 V battery charger source applied. The USB port supports interface to the computer running the SDK.

The EE-4XX series of eego amplifier is powered by the USB port connection to a computer.

### Statement of Intended Use

The eego amplifier is intended to be used by or under the direction of a physician for acquisition of EEG signals and to transmit them digitally to a computer. The device is intended for use on humans. The device is intended for use in a clinical environment (e.g., hospital, physician's office, etc). The device is not intended for use in life support systems.
