The CUP Electrodes are intended for non-invasive use with recording and monitoring equipment,(active and reference), of Electroencephalograph (EEG), electromyography (EMG)and Evoked Potentials(EP).

Device Description

A cutaneous electrode is an electrode that is applied directly to a patient's skin to record physiological signals. In other words cutaneous devices are used in the acquisition of signals for the purpose of monitoring and recording Electroencephalograph(EEG), Electromyograph(EMG), and Evoked Potentials(EP) and the electroencephalograph/evoked potentials reading is completely non-invasive procedure that can be applied to children and adult patients. The electrodes are delivered non-sterile and are available in disposable version. DAEHAN Disposable CUP electrodes are for single patient use only. The electrodes have a disc manufactured of molded ABS, Ag/agcl plated. The disc is permanently adhered to a lead wire. The insulated lead wires terminate using a molded touch proof connector (DIN 42 802) for electrical safety.

AI/ML Overview

This document is a 510(k) Summary for the DAEHAN Disposable CUP Electrodes. It describes the device, its intended use, and its substantial equivalence to predicate devices, but it does not contain the results of a study that proves the device meets specific acceptance criteria in the context of an AI/ML medical device.

The acceptance criteria mentioned in this document are for the DAEHAN Disposable CUP Electrodes as a cutaneous electrode, and the "studies" relate to general device performance and regulatory compliance for medical devices, not AI/ML performance.

Therefore, I cannot provide the requested information about acceptance criteria and a study proving an AI/ML device meets them based on the provided text.

Specifically, the document discusses:

Non-Clinical Test Summary:
- Biocompatibility: "Identical materials are used in legally marketed device"
- Performance Testing:
  - Bond Test
  - Electrical Properties Test (AAMI/ANSI EC12: Disposable ECG Electrodes, IEC 60601-1 Ed3.1 CL 8.5.2.3: Patient Leads)
- Shelf-life Testing (ASTM F1980-02)

These are standard tests for physical medical devices and do not involve AI/ML performance metrics like sensitivity, specificity, or AUC, nor do they involve a test set, ground truth established by experts, or MRMC studies.

If you have a different document related to an AI/ML medical device, please provide it, and I will be happy to extract the requested information.

Dear Da Roo Ha:

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. 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 located 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.

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

{2}------------------------------------------------

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 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.html; 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 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm.

For comprehensive regulatory information about mediation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/) and CDRH Learn (http://www.fda.gov/Training/CDRHLearn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic. See the DICE website (http://www.fda.gov/DICE) for more information or contact DICE by email (DICE@fda.hhs.gov) or phone (1-800-638-2041 or 301-796-7100).
