Intended Use
The REFA Physiological Amplifier family is intended to be used by or under the direction of a physician for acquisition of EEG, polygraphy and polysomnography signals and transmission of the signals to a PC during recording of neurophysical/ physiological research and exams. Polygraphy and Polysomnography may besides EEG, include physiological information such as EMG, ECG, EOG, EGG, PH, Respiration, Temperature and Oxygen Saturation.

No
The summary describes a physiological signal amplifier and does not mention any AI or ML capabilities, image processing, or data analysis beyond signal acquisition and transmission.

No
Explanation: The device is described as an amplifier for the acquisition and transmission of physiological signals (EEG, polygraphy, polysomnography) for research and exams, not for treatment.

Yes
The device is described as acquiring signals for "recording of neurophysical/physiological research and exams," which implies the collection of data for diagnostic purposes (e.g., EEG, polygraphy, polysomnography signals to assess neurological and physiological conditions).

No

The intended use describes a "Physiological Amplifier family" which is a hardware device used for signal acquisition and transmission. While software is likely involved in processing and displaying the signals, the core function relies on a physical amplifier.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states the device is for the acquisition and transmission of physiological signals (EEG, polygraphy, polysomnography) during neurophysical/physiological research and exams. This involves measuring signals from the body, not analyzing samples outside the body.
  • Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing biological samples (blood, urine, tissue, etc.)
    • Detecting or measuring substances within those samples
    • Providing information for diagnosis, monitoring, or treatment based on sample analysis

IVDs are specifically designed to perform tests on samples taken from the human body to provide information about a person's health. This device is designed to capture electrical and other physiological signals directly from the body.

Dear Mr. Wagner:

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. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0120. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its Internet address http://www.fda.gov/cdrh/dsma/dsmamain.html
