No
The device description focuses on the physical components and materials of the electrodes, and the performance studies are based on AAMI standards for electrical characteristics, with no mention of AI or ML.
No.
The device is described as a conductive medium between a patient and diagnostic equipment, indicating a diagnostic rather than therapeutic purpose.
No
Explanation: The device is described as a "conductive medium between the patient and the diagnostic equipment," and its components include a "Stainless Steel snap, that works as a connection point for the diagnostic equipment." This indicates the device is an accessory used with diagnostic equipment, rather than being diagnostic itself.
No
The device description clearly outlines multiple physical components (stainless steel snap, polypropylene label, various fabric/foam layers, Ag/AgCl sensor, gel, release liner) and describes their material composition and function. This indicates a hardware-based medical device, not a software-only one.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that these electrodes are used as a "conductive medium between the patient and the diagnostic equipment." They are facilitating the transmission of electrical signals from the patient to the equipment, not performing a diagnostic test on a sample taken from the body.
- Device Description: The description details the physical components of the electrodes, which are designed for external application to the skin to pick up electrical signals. There is no mention of analyzing biological samples (blood, urine, tissue, etc.).
- Performance Studies: The performance studies mentioned are related to the electrical properties and performance of the electrodes themselves (Bias Current Tolerance, DC Offset Voltage, etc.), not the accuracy of a diagnostic test performed on a sample.
- Lack of IVD Characteristics: There is no mention of reagents, calibrators, controls, or any other components typically associated with in vitro diagnostic tests.
In summary, this device is an accessory used with diagnostic equipment to acquire physiological signals from the patient's body. It does not perform a diagnostic test on a sample outside of the body, which is the defining characteristic of an IVD.

Intended Use / Indications for Use
These disposable noninvasive, hypoallergenic electrodes will be used as a conductive medium between the patient and the diagnostic equipment. Depending on the application, different sizes, shapes and a choice of eigher wet gel or solid hydrogel can be used for better results. These electrodes on be used for short-term or long-term applications, up to 3 days. This product is disposable and should only be used for single use.

Device Description
These Monitoring Electrodes are non-sterile, hypoallergenic, disposable, adhesive-backed with conductive centers, composed of materials commonly used in this application:
- First Layer: Stainless Steel snap, that works as a connection point for the diagnostic equipment.
- Second Layer: Polypropylene label substrate, used for reinforcement and a printable surface for branding.
- Third Layer: Various materials i.e., medical grade polyester fabric, polyethylene foam and paper, coated with bio-compatible adhesive.
Fourth Layer: Ag/AgCl. coated, 20% carbon filled plastic sensor.
Gel Foam Layer: Polyurethane foam. Only used for conductive wet gel.
Conductive Gel: Bio-compatible conductive solid hydrogel or wet gel
Fifth Layer: Silicone coated release liner to cover the adhesive and conductive media.
The electrodes are disposable and designed for single-patient use. They have a low profile construction that uses soft pliable and conformable materials for patient comfort. Because of the adhesive nature no extra securing materials are required to anchor the device to the patient's skin. The electrodes have one universal contact point which is a stainless steel snap. The equipment manufacturers provide the receptacle to this in the form of cither a snap lead wire or a pinch clip.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Safety and Effectiveness: Our electrodes are as safe and effective as Lead-Lok Inc. electrodes which were previously found to be substantially equivalent via 510(k) Premarket Notification K832877 and K911518/D.
The only two points of contact to the patients skin are the conductive gel and the adhesive-backed base material. Both conductive gels (wet gel and solid hydrogel), underwent the required skin sensitivity testing criteria as specified in the Triportite Biocompatibility Guidance for Medical Devices and ISO 10993-1 requirements for skin contact. These tests include Cytotoxicity, Sensitization, and Primary Skin Irritation (test results attached). As you will see, the solid hydrogel test results mention the name Vermont Medical, Lead-Lok/Shanghai Intco acquired this formula from Vernont Medical through a technology exchange. The adhesive backed materials are purchased from outside suppliers that use medical grade adhesive and also adhere to the same test criteria (test results attached)
The effectiveness of the electrodes was determined by running tests according to AAMI standards i.e., Bias Current Tolerance, DC Offset Voltage, AC Impedance, Combined Offset and Internal Noise, Recovery Slope Time and AC Impedance after Defind (test results attached).

Dear Mr. Healy:
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) 594-4646. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97) you may obtain.
