No
The device is a passive electrode for signal acquisition and does not involve any processing or analysis of the signals using AI/ML.
No
The device is described as electrodes used for recording and monitoring physiological signals (EMG, EEG, Evoked Potentials) and does not inherently provide a therapeutic effect.
No.
The device is an electrode that collects physiological signals (EMG, EEG, Evoked Potentials) for monitoring and recording equipment, rather than performing a diagnostic function itself. The diagnostic function would reside in the interpretation of the signals by separate equipment or a healthcare professional.
No
The device is a physical electrode, a hardware component, used to acquire physiological signals. The description details its materials and construction.
Based on the provided text, the Grass "DE-48-Plus Disposable Electrodes" are not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states the electrodes are for "non-invasive use with recording and monitoring equipment... of Electromyography (EMG), Electroencephalograph (EEG) and Evoked Potentials." These are all physiological measurements taken directly from the body, not from samples of bodily fluids or tissues.
- Device Description: The description emphasizes that the electrodes are "noninvasive, cutaneous devices, applied directly to the skin," and their purpose is to "pick up and transfer microvoltage signals, as generated by the body." This further reinforces their role in directly measuring physiological activity.
- Lack of IVD Characteristics: The text does not mention any analysis of biological samples (blood, urine, tissue, etc.) or any diagnostic testing performed on such samples. IVDs are specifically designed for testing in vitro (outside the body).
Therefore, the Grass "DE-48-Plus Disposable Electrodes" are classified as a medical device used for physiological monitoring and recording, but not as an In Vitro Diagnostic device.

Device Description
The Grass Technologies DE48-Plus Disposable Electrodes (various lengths) are noninvasive, cutaneous devices, applied directly to the skin, and used in the acquisition of physiological signals for the purpose of montoring and recording Electroencephalograph (EEG), PSG and similar physiological parameters.
Non-invasive, disposable surface electrode discs (Cutaneous Electrodes), as included in this submission, are applied to the skin using a cream or gel for adhesion. Their purpose is to pick up and transfer microvoltage signals, as generated by the body, to recording equipment, for the purpose of monitoring and recording associated with electroencephalography and electromyography. The new Grass DE-48-Plus electrodes, as with the BNT predicate, are manufactured with a circular, raised cup body molded from ABS plastic and coated with silver chloride (Ag/AgCl). The disc is adhered to a lead wire which is covered with heat shrink tubing and terminates with a molded connector that conforms to DIN 42-802 for electrical safety. Grass DE-48-Plus Electrodes connect to, and work with, any EEG equipment, without special attachments.
The DE-48-Plus electrodes are made up of the following materials (same or equivalent to the Rhythmlink predicate).
Cup Disk: ABS Plastic with an Aq/AqCl coating which is nominally measured at 10mm (8.5 to 10mm).
The connecting wire which is manufactured from 28AWG stranded Tin Copper conductor with soft PVC insulation.
Wire crimped to Cup Electrode using Tin plated copper tubing.
Terminal connected with Alex crimp type, 24-30AWG Brass, Tin plated, Molded in Palprene.

SUBSTANTIAL EQUIVALENCE
Grass Technologies believes that the DE-48-Plus Disposable Electrodes are substantially equivalent to the Rhythmlink Disc Electrodes as marketed under K061148 by Rhythmlink International, FDA Reg# 1067162 and to Grass Technologies' Gold Electrodes as marketed by Grass Technologies in the US prior to 1976.
DEVICE DESCRIPTION
The Grass Technologies DE48-Plus Disposable Electrodes (various lengths) are noninvasive, cutaneous devices, applied directly to the skin, and used in the acquisition of physiological signals for the purpose of montoring and recording Electroencephalograph (EEG), PSG and similar physiological parameters.

Dear Mr. Soares:
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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); 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 53)-542 of the Act); 21 CFR 1000-1050.
