More Information

Not Found

No
The device description and performance studies focus on the physical and electrical properties of a stimulating electrode, with no mention of AI or ML technologies.

No
The device itself is a stimulating electrode, which is an accessory to muscle stimulating devices. It's an interface, not the therapeutic device itself.

No.
The device is described as a "disposable, adhesive, conductive interface" between skin and muscle stimulating devices. Its function is to
transmit electrical signals for muscle stimulation, not to diagnose a condition. The "Summary of Performance Studies" focuses on skin irritation and effectiveness through impedance testing, not diagnostic accuracy.

No

The device description explicitly states it is a "disposable cutaneous TENS stimulating electrode consisting of a metal snap connector, adhesive foam and hydrogel (solid gel) conductive surface," which are physical components, not software.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Description and Intended Use: The description clearly states the device is a "disposable, adhesive, conductive interface between a patient's skin and muscle stimulating devices." It is applied to the patient's skin and interacts with external devices. It does not analyze samples taken from the body.
  • Lack of Biological Sample Analysis: There is no mention of analyzing any biological samples (blood, urine, etc.) in the description or intended use.

This device is a medical device, specifically an electrode used for muscle stimulation, but it does not fit the definition of an in vitro diagnostic device.

Trade/Device Name: Myo-trode SG Disposable Electrodes Regulation Number: 21 CFR 890.5850 Regulation Name: Powered muscle stimulator Regulatory Class: II Product Code: NUW Dated: June 2,2004 Received: June 4,2004

Dear Mr. Adib:

This letter corrects our substantially equivalent letter of July 20, 2004, regarding the classification of your device which was incorrectly identified as "unclassified."

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 (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 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.

Page 2 - Mr. Fray Adib

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 continue 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 (240) 276-0115. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 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.gov/cdrh/industry/support/index.html

Description of the Device: A disposable cutaneous TENS stimulating electrode consisting of a metal snap connector, adhesive foam and hydrogel (solid gel) conductive surface.

Intended Use: As a disposable, adhesive, conductive interface between a patient's skin and muscle stimulating devices manufactured by Myotronics-Noromed, Inc. including the Models J4, J5, and BNS-40.

Comparison with equivalent devices: The device is virtually identical to several devices that have previously been legally marketed. K010431 and K961141 (as above) are given as specific examples.

Safety & Effectiveness Information: There are no significant differences between the design and manufacture of the cited equivalent devices. Skin irritation was the only potential hazard identified by risk analysis. Patient contact materials have been tested by an independent testing laboratory and found to be "not an irritant" and to meet pertinent requirements of ISO 10993 (Test results on file.) Effectiveness was demonstrated through impedance testing.

Conclusion: The Myo-trode SG is substantially equivalent to the cited predicate devices, has been certified to meet current standards for irritation, cytotoxicity and allergic potential, and has been tested for effectiveness.
