Indications for Use

The EEG NeuroAmp is intended for biofeedback and relaxation purposes. To perform its intended function it must be used in combination with a computer and appropriate software. For purposes of this training task, information for feedback may be derived from one or two channels of EEG and from as many as three channels of peripheral physiology measures such as are conventionally used in biofeedback. The EEG NeuroAmp is intended to be used in the office by trained professionals who can ensure sound handling practices. The EEG NeuroAmp is not intended for diagnostic purposes. Federal law restricts this device to sale by or on the order of a physician or any other practitioner licensed by the State in which he practices to use or order the use of the device.

Device Story

EEG NeuroAmp serves as a high-performance interface between a client and a clinician's computer for EEG and peripheral biofeedback therapy. It accepts inputs from two EEG channels and three peripheral physiology channels (e.g., GSR, temperature via thermistor or infrared probe). The device features a built-in impedance meter with LED bar display to ensure electrode contact quality and includes notch filters to cancel power line interference. It provides audio, visual, or tactile feedback signals to the user. Used in clinical office settings, the device is operated by trained professionals. The clinician monitors the output via the Cygnet software, which displays real-time biofeedback data and alerts the clinician to 60-Hz contamination or poor electrode contact. By providing feedback on electrical brain activity and peripheral physiological measures, the device assists the patient in learning to control their physiological state to promote relaxed alertness.

Clinical Evidence

Bench testing only. Compliance with IEC 60601-1 (electrical safety) and IEC 60601-1-2 (EMC) confirmed. Biocompatibility testing for the pIRx3 sensor housing and elastic belt performed per ISO 10993-1; housing passed all tests, while the cotton belt passed dermal irritation and sensitization tests but is restricted to intact skin.

Technological Characteristics

Class II biofeedback device. 2-channel EEG amplifier (quasi-DC coupled, low-noise) and 3-channel peripheral sensor interface. 13-bit ADC resolution. 5th order Butterworth anti-aliasing filter. USB-powered with galvanic isolation. Impedance meter with LED bar display. Optional pIRx3 infrared temperature sensor. Connectivity via USB to PC running Cygnet software.

Indications for Use

Indicated for biofeedback and relaxation training in office settings by trained professionals. Not for diagnostic use.

Regulatory Classification

Identification

A biofeedback device is an instrument that provides a visual or auditory signal corresponding to the status of one or more of a patient's physiological parameters (e.g., brain alpha wave activity, muscle activity, skin temperature, etc.) so that the patient can control voluntarily these physiological parameters.

Special Controls

*Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter when it is a prescription battery powered device that is indicated for relaxation training and muscle reeducation and prescription use, subject to § 882.9.

KG | All three devices are intended for EEG biofeedback (neurofeedback). EEG biofeedback is a process that is intended to help the client to control his own state through shaping electrical brain activity in a manner that promotes a state of relaxed alertness. The NeuroAmp and the predicate device Procomp can also be used with other conventional biofeedback sensors. ProComp can be operated with a wider range of sensors than the NeuroAmp, e.g. with sensors intended for performing muscle reeducation. Therefore, the intended use of the NeuroAmp does not include biofeedback for the purpose of muscle reeducation, as that term is conventionally understood (application to spinal cord injury, etc). On the other hand, simply training the person toward a relaxed and alert state also has implications for regulation of the motor system. A trainee is likely to also feel motorically calmed. The differences in technological characteristics between EEG NeuroAmp and the predicate devices ProComp and Brainmaster can be summarized as follows: - Power supply via USB-port (5V) instead of battery supply (in the case of the Procomp) . {6}------------------------------------------------ | Title | Premarket Notification for EEG NeuroAmp | |---------------|-----------------------------------------| | Document Name | NeuroAmp_510(k).doc | | Issue | 1.1 | | Date | Feb.06.2008 | | | Corscience GmbH & Co. KG | - Results of electrode contact measurement (impedance check) are displayed directly on the . device - The impedance measurement needs to be engaged explicitly, and is disabled during EEG . neurofeedback. This feature differentiates the EEG NeuroAmp from the current Brainmaster, where the impedance measurement is continuous throughout. - . The device monitors galvanic voltages throughout the training process. - The bandwidth extends to lower EEG frequencies. . - The temperature range of the pIRx3 is narrower than that of the Procomp temperature sensor, . but is totally sufficient for measuring forehead temperature. The fact that the EEG NeuroAmp is powered via the serial port of the therapist computer does not affect safety or effectiveness because the device is galvanically isolated from the computer by means of a medical grade isolating transformer and has shown full compliance to IEC 60601-1. Since qood electrode contact quality is essential for effective EEG-biofeedback therapy, the easy-touse impedance measurement function of the NeuroAmp contributes to clinical success. The software provides for continuous monitoring of any 60-Hz contamination of the EEG, as an index to contact quality throughout the biofeedback process. The clinician is alerted on screen whenever criteria are violated. The NeuroAmp extends the bandwidth to lower frequencies than typical EEG amplifiers because these have turned out to be of biological interest as well. ### 5.13 Summary of Device Testing The EEG NeuroAmp and its optional accessory plRx3 have been tested according to IEC 60601-1 and IEC 60601-1-2 by accredited laboratories and have shown full compliance to these standards and the other standards listed in chapter 9 of this 510(k). The software was tested as described in section 16 "Software". The optional accessory "passive infrared temperature sensor plRx3" has been tested according to ISO 10993-1 by an FDA recognized testing laboratory according to GLP standards. The housing material and the elastic belt that fastens the device to the head have both been tested. The elastic belt conforms to the German "Oko-Tex-Standard" which is a quality mark for clothing regarding certain residues. The belt is made of cotton and therefore did not pass the test for cytotoxicity. Due to this effect the belt is suitable for use on intact skin only. It did pass the tests for dermal irritation and sensitization. Normally, there is hair between the blient's skin, unless the client is bald. The housing material has passed all tests. It shows full compliance to the standard 10993-1. See also section 15 "Biocompatibility". ### 5.14 Conclusions Based on the above, Corscience GmbH & Co. KG concludes, that EEG NeuroAmp is substantially equivalent to legally marketed predicate devices and iffective for its intended use, and performs as well as or better than the predicate devices. {7}------------------------------------------------ Image /page/7/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
