Device Story

Wireless TENS & EMS (Models SM9110, SM9113, SM9116) provides electrical stimulation for pain relief and muscle conditioning. Device delivers electrical pulses via skin-contact electrodes to nerves (TENS) or muscles (EMS/NMES). Operated by patients (OTC) or clinicians (prescription) to manage pain, relax spasms, increase circulation, prevent atrophy, or facilitate muscle re-education. Output intensity and pulse parameters are controlled by the user to achieve therapeutic effect. Benefits include non-pharmacological pain management and physical rehabilitation support.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Wireless TENS/EMS stimulator; electrical pulse output; intended for OTC and prescription use; multi-model configuration (SM9110, SM9113, SM9116).

Indications for Use

Indicated for OTC use for temporary relief of muscle pain (shoulder, waist, back, arm, leg) due to exercise/activity, and for stimulation of healthy muscles to improve performance. Indicated for prescription use for chronic intractable pain, post-traumatic/post-surgical pain, muscle spasm relaxation, increased local blood flow, prevention/retardation of disuse atrophy, muscle re-education, range of motion maintenance, and post-surgical calf muscle stimulation to prevent venous thrombosis.

Regulatory Classification

Identification

A transcutaneous electrical nerve stimulator for pain relief is a device used to apply an electrical current to electrodes on a patient's skin to treat pain.

Dear Doris Dong:

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

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/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); 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.
