Dear Rob Packard:
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 (the 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 available 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.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).
Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).
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 (reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reporting-combination-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 Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.
All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).

IV. DESCRIPTION OF THE DEVICE
The actiTENS mini is a connected medical device for transcutaneous electrical nerve stimulation (TENS) intended to treat pain in adults. It also contains an electrical muscle strengthening (EMS) program. It is intended for people over 22 years of age with unimpaired intellectual abilities. The actiTENS mini is fixed directly on the body using a fastening accessory. It adapts to the shape of the body with its flexible design. The actiTENS mini can be used discreetly during daily activities.
The EIG (electrical impulse generator) generates electrical impulses that are diffused in the body through skin electrodes connected to one or two channels via cables available in various lengths. Managing the EIG is done by means of the actiTENS Mobile App that allows users to control the stimulation session by choosing: a stimulation program, the number of channels used, the stimulation intensity for each channel and the stimulation duration.
It is intended to be used by the patient at home and for therapeutic application by medical professionals.

INDICATIONS FOR USE COMPARISON
The subject device and primary predicate device (K202159) have the same indications for use with the exception that the predicate device does not include over-the-counter-use.
The subject device and the predicate device (K182203) have equivalent indications for use, including over-the-counter use.
VI. SUMMARY OF TECHNOLOGICAL CHARACTERISTICS
TECHNOLOGICAL COMPARISON
The subject device, primary predicate device, and secondary predicate device have equivalent technological characteristics. All three devices claim one function: electrical stimulation. Concerning the maximum output voltage and the maximum output current, the subject device and the primary predicate device have been developed as a current generator with a maximum setpoint current of 60mA and has been limited by hardware to deliver output voltage of 60V. Thus it delivers a current of 60mA at 60V for 1KΩ. Above this charge the maximum output power will decrease. In both cases the maximum output current and maximum output voltage of the subject device are in the same range to this of the predicate. The subject device presents a maximum phase charge in the same range to this of the predicate device. The maximum current density and maximum average power density are directly linked to the electrodes surfaces used with the device. They are calculated for the subject device using the smallest electrodes provided/recommended for use, the values stay in the same order of magnitude as this of the predicate device. For the maximum current density it stays under 2 mA/cm², and the maximum power density stays well under 0,25 W/cm². These technological differences between the subject and predicate device do not impact safety and effectiveness.

VII. SUBSTANTIAL EQUIVALENCE COMPARISON TABLE
The following characteristics were compared between the subject device and the predicate device in order to demonstrate substantial equivalence:

X. CONCLUSIONS FROM NONCLINICAL AND CLINICAL TESTS
The subject device, actiTENS mini, has the same indications for use when compared with the predicate devices (K202159 and K182203). The subject device and the predicate devices have similar technological characteristics. Non-clinical benchtop testing shows that the subject device is substantially equivalent in terms of safety and effectiveness when compared with the predicate device and performs as well as the predicate.
