No
The summary describes a device for acquiring and transmitting EEG signals. There is no mention of AI, ML, or any data processing beyond signal acquisition and transmission. The performance studies focus on electrical safety, usability, and signal integrity, not algorithmic performance.
No
The device is described as an amplifier for acquiring and transmitting EEG signals, indicating it is a diagnostic tool rather than a device for treatment.
Yes
The device is intended for the "acquisition of EEG signals." EEG signals are used by physicians to diagnose neurological disorders and other medical conditions, making it a diagnostic tool.
No
The device description explicitly states "The Delphi Amplifier has been designed as a mobile recording device for EEG (electroencephalography) signals" and details hardware components like input channels, USB connection for power and data, and impedance measurement capabilities. This indicates it is a hardware device with accompanying software, not a software-only medical device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Delphi Amplifier Function: The Delphi Amplifier acquires EEG signals directly from the human body. It measures electrical activity in the brain. This is an in vivo measurement, not an in vitro measurement of a specimen.
- Intended Use: The intended use clearly states it's for "acquisition of EEG signals" and transmitting them digitally. This aligns with measuring physiological signals directly from the patient.
Therefore, based on the provided information, the Delphi Amplifier is a medical device for physiological signal acquisition, not an In Vitro Diagnostic device.

Device Description
The Delphi Amplifier has been designed as a mobile recording device for EEG (electroencephalography) signals. It provides access to recorded data over a USB connection to external software over its signal driver interface. The Delphi Amplifier is powered via a USB connection and does not require any additional power source. The Delphi Amplifier supports EEG acquisition and storage by Referential DC input channels, and Parallel trigger input channels.
The Delphi Amplifier enables connection of up to 48 referential channels and 8bit trigger input channel. Impedance values can be measured for all referential electrodes as well as the reference. An SDK (Software Development Kit) is available for direct amplifier communication.
The device is powered by the USB port connection to a computer. The USB port supports interface to the computer running the SDK.

Dear Bosmat Friedman-Cox:
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 (the 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.
Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device"

(https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).
Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30. Design controls; 21 CFR 820.90. Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the OS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).
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 of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.
All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rue"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advicecomprehensive-regulatory-assistance/unique-device-identification-system-udi-system.
