Intended Use
Specific indications: used to apply an electrical current to electrodes on patient's skin to function as: - Relaxation of muscle spasms - Prevention or retardation of disuse atrophy ● - . Muscle re-education - Immediate post-surgical stimulation of calf muscles to prevent venous thrombosis - . Maintaining or increasing range of motion
Device Description
A sequenced system for transcutaneous muscle stimulation consists of a stimulator, a sequencer for channel selection, patient cable, and electrodes applied to the skin. Various types of waveforms may be output to generate the desired effect on the muscle(s) to be treated, and the patient is given control of the signal intensity for personal safety and comfort. Sequenced system may have more than on output channel in order to operate bilaterally on the body or to treat multiple regions simultaneously or serially in a prescribed sequence.
More Information

Not Found

No
The description focuses on standard electrical stimulation technology and does not mention any AI/ML components or capabilities. The "Not Found" entries for AI/ML mentions and training/test data descriptions further support this conclusion.

Yes
The device is intended to treat specific medical conditions, such as muscle spasms, disuse atrophy, and for post-surgical stimulation, which are therapeutic applications.

No

The device is described as a "sequenced system for transcutaneous muscle stimulation" used to apply electrical currents to the skin to achieve therapeutic effects such as muscle relaxation, prevention of disuse atrophy, and muscle re-education. Its stated functions are interventional/therapeutic, not diagnostic.

No

The device description explicitly lists hardware components such as a stimulator, sequencer, patient cable, and electrodes, indicating it is not software-only.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
  • Device Function: The described device applies electrical current to the patient's skin for therapeutic purposes related to muscle function (relaxation, atrophy prevention, re-education, etc.). It directly interacts with the patient's body externally.
  • Lack of Specimen Analysis: There is no mention of analyzing any biological specimens from the patient.

The device falls under the category of a therapeutic medical device used for physical therapy or rehabilitation.

Dear Dr. Jen:

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 Center for Devices and Radiological Health's (CDRH's) Office of Compliance at (240) 276-0120. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). For questions regarding postmarket surveillance, please contact CDRH's Office of Surveillance and Biometric's (OSB's) Division of Postmarket Surveillance at (240) 276-3474. For questions regarding the reporting of device adverse events (Medical Device Reporting (MDR)), please contact the Division of Surveillance Systems at (240) 276-3464. You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at toll-free number (800) 638-2041 or (240) 276-3150 or the Internet address http://www.fda.gov/cdrh/industry/support/index.html.
