No
The description focuses on the hardware (amplifier, digitization) and basic data transmission to a host computer for analysis. There is no mention of AI/ML algorithms for data processing or interpretation.
No.
The device is used for measuring, recording, and analyzing electrical activity for monitoring and diagnosis (EEG), not for providing therapy.
Yes
The device is described as aiding in "monitoring and diagnosis" of the electrical activity of the brain, a function explicitly tied to diagnostic purposes in clinical settings for EEG.
No
The device description explicitly details hardware components such as an amplifier, AC/DC adapter, and USB connector cable, indicating it is not a software-only device.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- Intended Use: The intended use is to measure, record, and analyze the electrical activity of the brain (EEG) to aid in monitoring and diagnosis. This is a measurement of physiological signals directly from the patient's body.
- Device Description: The device is an amplifier and digitizer that processes electrical signals from electrodes attached to the body. It does not analyze samples taken from the body (like blood, urine, tissue, etc.).
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, reagents, or any of the typical components or processes associated with IVD devices.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic purposes. This device is a physiological signal acquisition and processing system.

Device Description
The g.USBamp is a fully programmable system which provides a total of 16 analog input channels each of which can be configured, amplified and converted to digital form (analog to digital conversion). The applied part is optically isolated. The amplifier receives its power from a dedicated AC/DC adapter, meeting the IEC 601-1 requirements, which feeds in +5V DC. Internally, the +5V DC is further isolated by a dedicated DC/DC type converter.
The g.USBamp is intended to be used for measuring, recording and analysing of electrical activity of the brain and/or through the attachment of multiple electrodes at various locations to aid in monitoring and diagnosis as routinely found in clinical settings for EEG. It captures the data, converts it into digital form and passes it on to a host computer running appropriate software. The device can be used for adults, children, infants and animals. The host computer must use Microsoft XP. g.USBamp comes with a C Application Programming Interface (C API) which allows to control the device.
The system consists of the AC/DC adapter (power supply unit), g.USBamp (the amplification and digitization unit), a USB connector cable to connect the device to a host computer and the C API.
g.USBamp works in the same manner as the approved and predicate device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The amplifier was tested with an external signal generator which applies sinusoidal signals with different frequencies and amplitudes to the inputs of the amplifier. The correct signal transmission and amplification are determined with BODE diagrams for each channel. The impedance measurement was tested with test impedances.

Dear Mr. Preiss:
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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
