GEODESIC EEG SYSTEM, MODEL 200 by ELECTRICAL GEODESICS, INCORPORATED

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

Device Description

The Geodesic EEG System is a digital electroencephalography system (EEG) with a dense sensor array of 32 to 256 channels. Like existing digital EEG systems, the Geodesic EEG System is computer controlled and capable of acquiring, storing, and displaying data. It includes scalp conductive electrodes, amplifiers, a central processing unit, and software. The Geodesic Sensor Net is a dense array of scalp electrodes designed to allow rapid application in an even distribution across the head. The Net Amps " consists of multiple amplifiers for physiological signals that are fully software controlled. Net Station® is the software package that provides control of the Geodesic EEG System, digital data storage, and operator-selected waveform displays. The software does not perform any data analysis. Additional components of the system are an articulated arm with extended cable, rack system, various cables, standard components of personal computer (monitor, keyboard, mouse), electrolyte solution, and disinfectant.

AI/ML Overview

This document describes the Geodesic EEG System™, an electroencephalography system. The provided text does not contain information about acceptance criteria or a study proving that the device meets specific performance criteria, beyond general safety and electromagnetic compatibility compliance.

Here's a breakdown of the requested information, with explanations based on the provided text:

A table of acceptance criteria and the reported device performance

Acceptance Criteria	Reported Device Performance
Not specified	Not specified
General Safety (CAN/CSA C22.2 No. 601.1-M90, UL Std. No. 2601-1)	Passed
Electromagnetic Compatibility (EN60601-1-2(1993))	Passed
Electroencephalograph Standards (IEC 60601-2-26, CAN/CSA C22.2 No. 601.2.26)	Passed
Biocompatibility (ISO 10993)	Passed

Explanation: The document explicitly states: "Comparative performance testing and clinical evaluations were not submitted as part of this 510(k)." The "Testing conducted" section lists compliance with various international standards related to electroencephalographs, safety, electromagnetic compatibility, and biocompatibility, and states that the "Geodesic EEG System passed all testing." However, these are general compliance standards, not specific acceptance criteria for a device's performance in, for example, detecting certain EEG patterns or achieving a particular level of signal-to-noise ratio.

Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

Explanation: The document states, "Comparative performance testing and clinical evaluations were not submitted as part of this 510(k)." Therefore, there is no information on sample size, test set characteristics, or data provenance. The 510(k) submission relied on substantial equivalence to predicate devices and compliance with general safety and performance standards, rather than a new comparative performance study.
Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

Explanation: As no comparative performance or clinical evaluations were submitted, there was no test set for which ground truth needed to be established by experts.
Adjudication method (e.g. 2+1, 3+1, none) for the test set

Explanation: Not applicable, as no test set or clinical evaluations were submitted.
If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Explanation: No MRMC comparative effectiveness study was done. The document explicitly states: "Comparative performance testing and clinical evaluations were not submitted as part of this 510(k)." Furthermore, the described device (Geodesic EEG System) is a diagnostic tool for measuring and recording EEG data; its software ("Net Station®") "does not perform any data analysis." This indicates it's a data acquisition system and not an AI-assisted diagnostic tool.
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Explanation: Not applicable. The device is an EEG acquisition system. Its software explicitly states it "does not perform any data analysis." Therefore, there is no algorithm for standalone performance testing in terms of diagnostic interpretation.
The type of ground truth used (expert consensus, pathology, outcomes data, etc)

Explanation: Not applicable, as no comparative performance or clinical evaluations were submitted that would require the establishment of an independent ground truth for diagnostic purposes.
The sample size for the training set

Explanation: Not applicable. The device is an EEG acquisition system, and its software does not perform data analysis, which would typically be a function of a machine learning or AI algorithm that requires a training set. The submission is for a device that measures and records electrical activity, not one that interprets it using learned patterns.
How the ground truth for the training set was established

Explanation: Not applicable, for the same reasons as #8.

510(k) SUMMARY

Submitter's name: Electrical Geodesics, Inc. 1850 Millrace Drive Eugene, OR 97403 541-687-7962

Date summary prepared:

June 25, 2001

Device name:

Proprietary name: Common or usual name: Classification name:

Geodesic EEG System™ EEG machine Electroencephalograph, 84 GWO Class II, 21 CFR 882.1400.

The product includes the Geodesic Sensor Net® which has the following identifiers:

Common name:	EEG electrode
Classification name:	Cutaneous electrode, 84 GXYClass II, 21 CFR 882.1320.

Legally marketed device for substantial equivalence comparison:

For the Geodesic EEG System it is the Bio-Logic Ceegraph 128-Channel Recording System submitted by Bio-Logic Systems Corporation and cleared for marketing under 510(k) *K973883. For the Geodesic Sensor Net, the predicate device is the Electro-Cap VII System submitted by Electro-Cap Inc. and cleared for marketing under 510(k) *K780045.

Description of the device:

The Geodesic EEG System is a new device that has not previously been submitted to FDA. It has features similar to other digital EEG devices on the market.

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

Intended use of device:

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

Technological characteristics:

The technological characteristics of the Geodesic EEG System are similar to those of other digital EEG systems, including the predicate device, the Ceegraph 128-Channel Recording System. Each product is an EEG machine that is software controlled, can accommodate a variable number of electrodes, and can acquire, display, and record EEG data. Some differences in electrical parameters are described. Differences in the software include that the products use different operating systems and that Net Station does not analyze the data. Another difference is that the Geodesic EEG System has dedicated electrodes, the Geodesic Sensor Net.

The Geodesic Sensor Net is compared to the Electro-Cap VII System. Each product consists of a structure that links a number of electrodes so that they can be easily applied to the patient. The Geodesic Sensor Net uses a geodesic array of electrodes with equal distribution across the head. The Electro-Cap uses the 10-20 array. The Geodesic Sensor Net can accommodate a larger number of electrodes. Finally, the Geodesic Sensor Net does not require scalp abrasion for use.

Testing conducted:

Testing was conducted to ensure compliance with international standards related to electroencephalographs. The general safety standards used were: CAN/CSA C22.2 No. 601.1-M90 including Supplement 1 and Amendment 2 and UL Std. No. 2601-1 (2nd Edition). The electromagnetic compatibility standard was EN60601-1-2(1993). The electroencephalograph standards were IEC 60601-2-26 and CAN/CSA C22.2 No. 601.2.26. The biocompatibility standard was ISO 10993. The Geodesic EEG System passed all testing.

Performance testing:

Comparative performance testing and clinical evaluations were not submitted as part of this 510(k).
