Electrical Stimulation
The Flexible Rubber Electrodes are a family of electrodes that are supplied as accessories to Enraf-Nonius B.V. nerve and muscle stimulation equipment. Depending on electrode size and connection terminals, the following parts apply: 1460265 6 x 8 cm electrode with 4 mm female connection terminal, 1460272 4 x 6 cm electrode with 4 mm female connection terminal, 1460274 8 x 12 cm electrode with 4 mm female connection terminal, 3444128 4 x 6 cm electrode with 2 mm female connection terminal, 3444129 6 x 8 cm electrode with 2 mm female connection terminal, 3444130 8 x 12 cm electrode with 2 mm female connection terminal. The electrodes consist of carbon filled silicon rubber. For proper electrical contact with the patient the electrodes should be used in combination with moistened sponge pads. The electrode/sponge assembly is wrapped to the patient using fixation straps. Instructions for use are available in the Operating Instructions of the Enraf-Nonius B.V. nerve and muscle stimulators that the electrodes are to be used with. The following accessories apply: 1460266 Sponges Pads 6 x 8 cm, set of 4 pc, 1460273 Sponges Pads 4 x 6 cm, set 4 pc, 1460275 Sponges Pads 8 x 12 cm, set 4 pc, 3444020 Fixation strap 100 x 3 cm, 3444021 Fixation strap 250 x 3 cm.
The provided text is a 510(k) Summary for Flexible Rubber Electrodes. It describes the device, its indications for use, and a comparison of its technological characteristics to a predicate device. However, it does not contain any information about acceptance criteria, device performance metrics, or study designs (like sample sizes, expert involvement, or adjudication methods) that would typically be associated with proving a device meets acceptance criteria in the context of an AI/ML medical device.
The document is a submission for regulatory clearance (510(k)) for a physical medical device (electrodes), not an AI/ML product. The "Substantial Equivalence Summary" part focuses on comparing the new electrodes to existing ones based on physical characteristics (current density, power density), adherence to standards (IEC, MDD, CFR), and biocompatibility (cytotoxicity, skin irritation, dermal sensitization). These are traditional engineering and safety evaluations, not performance metrics derived from AI/ML models.
Therefore, I cannot provide the requested information about acceptance criteria for an AI/ML device or its associated study, as that content is not present in the provided document.

Substantial Equivalence Summary
Electrodes 1460265, 1460272 combined with sponge pads 1460266 and 1460273, were already used as accessories to the Enraf-Nonius B.V. Endomed CV405 powered muscle stimulator, a device no longer in production. The electrodes were continued to be used with newer Enraf-Nonius B.V. stimulator designs marketed outside the USA. During this time the electrodes have undergone the following changes:
- Electrode size 8 x 12 cm was added to the family .
- Electrodes were made available with 2 mm female terminations ●
- A new material formulation was used .

Dear Mr. Coelet:
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 (301) 594- _ . 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.qov/cdrh/dsma/dsmamain.html
