More Information

No
The description focuses on standard electrical stimulation technology and does not mention any AI or ML components or capabilities.

Yes
The device is described as an "electrical nerve stimulator indicated for use for pain relief," and its intended use is for "temporary relief of pain associated with sore and aching muscle." These characteristics align with the definition of a therapeutic device.

No

The intended use of the device is for temporary relief of pain associated with sore and aching muscles due to strain, and it functions as an electrical nerve stimulator for pain relief. It does not mention any function for identifying, detecting, or monitoring a disease or condition.

No

The device description explicitly lists hardware components such as LCD, Control Key, Switch, Battery, Output jack, and USB port, and accessories like electrodes and cables. It also mentions differences in battery specifications, LCD dimensions, and PCB dimensions between models, all of which are hardware characteristics.

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

Here's why:

  • Intended Use: The intended use is for the temporary relief of pain associated with sore and aching muscles. This is a therapeutic use, not a diagnostic one.
  • Device Description: The device is described as an electrical nerve stimulator (TENS) that applies electrical current to the skin for pain relief. This is a physical therapy modality, not a method for testing samples from the human body.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific substances, or providing diagnostic information about a disease or condition.

IVD devices are used to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. This device does not fit that description.

Similarities between proposed device and predicate device:
Per IEC 60601-2-10, 51.104, it states that for equipment intended for therapeutic applications: with a load
resistance of 5002 the output current r.m.s shall not exceed the limit of 50mA in case of Frequency ≤400Hz; and the
RMS output current of the proposed device which is calculated based on the frequency parameters meets the IEC

Comparison Summary:

The proposed device is compared to the predicate device in terms of power source, waveform, shape, pulse duration, net charge, frequency, pulse period and stimulus delivered of each mode. Based on the analysis of similar/different points between the proposed device and predicate device, the proposed device is finally considered to be substantially equivalent to the predicate device; and the differences will not affect the safety and effectiveness of the proposed device.

    1. Biocompatibility Summary
      The patient-contact component of the proposed device is the GMDASZ TENS Electrodes. The biocompatibility of the GMDASZ TENS Electrodes has been demonstrated in K092546. It was tested for cytotoxicity (ISO 10993-5), sensitization (ISO 10993-10), and irritation sensitivity (ISO 10993-10) with the test result in K092546. The biocompatibility of predicate device was demonstrated in term of cytotoxicity (ISO 10993-5), sensitization (ISO 10993-10), and irritation sensitivity (ISO 10993-10) in K102598. Therefore the biocompatibility of the proposed device is considered to be substantially equivalent to that of the predicate device (K102598).
  • Usability Discussion 8.
    In order to validate the usability performance of TENS device for US market, the sponsor organized a usability study in America. The study focused on the labeling information to support the safe and effective use of the proposed device.

The usability study demonstrated that the final version of the labeling for the TENS, were well understood by a variety of "patients", and provided sufficient information for safe and proper use of the device.

  • Non-Clinical Test Conclusion 9.
    Bench tests were conducted to verify that the proposed device met all proposed design specifications. The test results demonstrated that the proposed device complies with the following standards:

IEC 60601-1: 1988+ A1: 1991+ A2: 1995, Medical Electrical Equipment- Part 1: General requirements for safety.

IEC 60601-1-2: 2007. Medical Electrical Equipment- Part 1: General requirements for basic safety and essential performance - Collateral Standard: Electromagnetic compatibility- Requirements and tests

IEC 60601-2-10: 1987/A1: 2001, Medical electrical equipment, Part 2: Particular requirements for the safety of nerve and muscle stimulators.

10. Substantially Equivalent Conclusion

The electrical stimulation provided by a series of model SM9066, SM9090, SM9098, SM9128 and SM9198 are similar to the commonly employed TENS devices that have been cleared for marketing without prescription labeling.

These models have the same intended use and the similar technological characteristics as those OTC predicates. Moreover, verification and validation tests contained in this submission demonstrate that the difference in these models still maintain the same safety and effectiveness as that of the cleared devices.

In other words, those engineering differences do not: (1) affect the intended use or (2) alter the fundamental scientific technology of the device.

The adequate guidance to the user on electrode application and electrode placement are presented in the User Manual; the information is used to insure the electrode can be used safely and effectively.

We believe that there are no new safety or effectiveness issues concerning this device to be introduced. Technological characteristics, features, specifications, materials and intended uses of the series of model SM9066, SM9088, SM9090, SM9098, SM9128 and SM9198 are substantially equivalent to the quoted predicated devices.

The differences that exist between the devices are insignificant in the terms of safety or effectiveness. The proposed device, TENS, Model of SM9066, SM9088, SM9090, SM9098, SM9128 and SM9198 is determined to be Substantially Equivalent (SE) to the predicate device, K102598, in respect of safety and effectiveness.
