Intended Use

This is an EEG electrode set intended for routine clinical settings where rapid placement of a large number of EEG electrodes is desired.

Device Story

WaveGuard Net EEG Cap is a reusable electrode array for EEG signal acquisition. Device consists of saline-soaked sponge electrodes (Ag-plated polyurethane substrate) mounted in a silicone mesh cap; includes chin-strap and cable bundles with connectors. Electrodes are arranged in international 10/10, 10/20, 10/5, or equidistant 'Duke' layouts. Used in clinical settings by healthcare professionals to facilitate rapid, multi-channel EEG electrode placement. Output is raw electrical brain activity signals transmitted via cables to compatible EEG amplifiers (e.g., eego EE-2xx/EE-5xx series) for clinical interpretation. Benefits include reduced setup time for high-density EEG recordings. Device is MR unsafe.

Clinical Evidence

Bench testing only. Biocompatibility testing performed per ISO 10993-1, -5, -10, -12, -17, -18, and -23. Compliance with 21 CFR Part 898 performance standards for electrode lead wires and patient cables confirmed.

Technological Characteristics

Materials: Ag-coated polyurethane electrodes, silicone mesh cap. Sensing: Saline-soaked sponge electrodes. Connectivity: Wired connection to EEG amplifiers via standard connectors. Form factor: 6 sizes (infant to adult). Reusable after cleaning. Complies with 21 CFR Part 898.

Indications for Use

Indicated for infants up to any age in routine clinical settings requiring rapid placement of multiple EEG electrodes.

Regulatory Classification

Identification

A cutaneous electrode is an electrode that is applied directly to a patient's skin either to record physiological signals (e.g., the electroencephalogram) or to apply electrical stimulation.

Trade/Device Name: WaveGuard Net EEG Cap (NA-245, NA-261, NA-261, NA-265, NA-271, NA-281) Regulation Number: 21 CFR 882.1320 Regulation Name: Cutaneous Electrode Regulatory Class: Class II Product Code: GXY Dated: October 11, 2024 Received: October 11, 2024

Dear Dana Coggin:

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.

{1}------------------------------------------------

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 QS 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 Rule"). 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-device-advicecomprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
