## Legally Marketed Predicate Device(s)

Geodesic EEG System™ 300 (GES 300) by Electrical Geodesics, Inc. K063797

## Device Description

The Geodesic EEG System™ 400 Series (GES 400) is a digital electroencephalograph system (EEG). Each system consists of an amplifier, central processing unit, software, electrodes, and components of a standard personal computer (monitor, keyboard, and mouse).

The GES 400 Series consists of 3 models (GES 400, GES 405, and GES 410), each of which has a slightly different amplifier. The amplifiers are very similar and all are called Net Amps ". They vary in connectors used to attach the electrodes and in the A/D chips, which support different maximum sampling rates. The other parts of the GES 400 Series are identical and consist of an isolation transformer, a power supply, Net Station software, proprietary EEG electrodes, and data acquisition computer. Optional accessories include a cart that holds the components of the system, interface cable, and articulated arm. The GES 400 Series also accepts third party DIN 42802 electrodes and an SpO22 electrode.

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

## Intended Use/Indications for use

The Geodesic EEG System 400 Series™ (GES 400) is intended to measure and record the electrical activity of the patient's brain. It can be used on adults, children, and infants.

## Substantial Equivalence Comparison

The GES 400 Series is a modification to the Geodesic EEG System™ 300. In the charts below, the column labeled GES 400 gives a full description for comparison with the predicate device, GES 300. "Same" in the GES 405 and GES 410 columns means that this item is identical to the GES 400.

#### Table 1: Overall Comparison

The overall features of the GES 400 Series and the GES 300 are very similar. They have the same basic components and accept the same electrode types. The software has been upgraded from Net Station 4.2 to Net Station 4.5. There are three models of amplifier, which lead to the three models in the GES 400 Series. These amplifiers are described more fully in Table 2. As noted in Table 1, the Net Amps 400 and Net Amps 410 accept HCGSN electrodes with a Hypertronics connector, just like the GES 300. The Net Amps 405 accepts HCGSN electrodes with a GEM connector, which was cleared with the Geodesic EEG System Mobile (GEM) under K 112353. The electrodes used with all models are identical.

In overall features the GES 400, GES 405 and GES 410 are substantially equivalent to the GES 300.

#### Table ?. Amplifier Comparison

Both the Net Amps 400 Series and the Net Amps 300 are very similar. The Net Amps 400 and 410 accept the same number of channels as the Net Amps 300. Because the Net Amps 405 accepts only the GEM connector the maximum number of channels is 32. The sampling rate varies in the Net Amps 400 series, though the sampling rate in the Net Amps 410 is identical to the Net Amps 300. The input impedance of all the Net Amps 400 models has been improved with respect to the Net Amps 300. The digital interface and the embedded processor have changed from the Net Amps 300. Both of these hardware changes are upgrades to widely used current technologies. All other amplifier features are the same. None of the differences between the Net Amps 400 Series amplifiers and the Net Amps 300 raise new issues of safety and effectiveness.

{3}------------------------------------------------

## Testing

Electrical safety and electromagnetic interference testing have been conducted to UL 60601-1, IEC 60601-1-2, IEC 60601-2-26, CAN/CSA 601.1-M90, and CAN/CSA 60601-2-26. Additional standards used in the development of the product were EN 62304 and EN 62366. Verification and validation testing of the software has also been conducted.

No animal or clinical testing was submitted.

## Conclusion

The Geodesic EEG System™ 400 Series (GES 400) is substantially equivalent to the Geodesic EEG System™ 300 (GES 300) based on intended use and device features.
