## 6. Device Description

The subject device is a self-adhesive TENS device with 15 adjustable intensity levels for pain relief. Moreover, it also provides a heat function which can be used alone, or in conjunction with the TENS function simultaneously. TENS, Transcutaneous

{4}------------------------------------------------

Electrical Nerve Stimulation, refers to the electrical stimulation of nerves through the skin which is an effective method of pain relief. It can be used for self-treatment. Any symptoms that could be relieved using TENS must be checked by your general practitioner who will also give you instruction on how to carry out a TENS self-treatment regime.

TENS device works by passing electrical currents over the skin via a set of gel pads. As a transfer medium, the gel pads are subject to natural wear and tear, and must be replaced when they stop providing sufficient contact or the main unit no longer sticks to the skin completely. Failure to replace the gel pad may lead to skin irritation as a result of heightened current density in particular areas.

This device is only compatible with the 50 mm x 56 mm gel pads which are the OTC medical device cleared by FDA under K132588, and come with the device.

# 7. Intended Use / Indications for Use of the Device

The subject device is designed for symptomatic relief and management of chronic pain, and for temporary relief of pain associated with sore and aching muscles in the shoulder, waist, back, neck, upper extremities and lower extremities due to strain from exercise or normal household work activities. It is also indicated for temporary relief of pain associated with dysmenorrhea (menstrual cramps) when used with over-the-counter pain medication. In addition, it also provides a heat function intended to temporarily relief of minor aches and pains.

## 8. Non-clinical Testing

A series of safety and performance tests, as follows, were conducted on the subject device in accordance with FDA recognized consensus standards and/or guidance:

- Shelf life (ASTM F1980-16)
- Biocompatibility (ISO 10993-1 Edition 4.0, ISO 10993-5 Edition 3.0 and ISO 10993-10 Edition 3.0)
- Software validation (IEC 62304 Edition 1.1)
- Electromagnetic compatibility and electrical safety (ANSI/AAMI ES60601-1:2015/(R)2012, IEC 60601-1-2 Edition 4.0, IEC 60601-1-11 Edition 2.0 and IEC 60601-2-10 Edition 2.1)
- Function test (Guidance Document for Powered Muscle Stimulator 510(K)s. Document issued on: June 9, 1999)
- Usability test (IEC 60601-1-6 Edition 3.1 and IEC 62366-1 Edition 1.0)

{5}------------------------------------------------

All the test results demonstrate the subject device, HEATING TENS (FT-615), meets the requirements of its pre-defined acceptance criteria and intended use, and its substantially equivalent to the predicate device.

# 9. Clinical Testing

No clinical test data was used to support the decision of substantial equivalence.

# 10. Comparison of Differences and Substantial Equivalence Determination

The subject device, HEATING TENS (FT-615), submitted in this 510(k) file is substantially equivalent in intended use, design, functions, technology, operation principles, materials, PCBA, software, electrode area and performance to the cleared HIVOX OTC Electrical Stimulator (FT610-B)(K211403). Differences between the devices cited in the following do not raise any new issue of substantial equivalence.

| HEATING TENS | HIVOX OTC Electrical<br>Stimulator | N/A | |
| FT-615 | FT610-B | | |
| Housing | | The housing is different but<br>all of them material are same.<br>It does not affect the intended<br>use, biocompatibility or alter<br>the fundamental scientific<br>technology of subject device. | |
| | Dimensions | | Slight different in device<br>dimensions because the<br>design of product appearance.<br>However, it does not affect<br>the usability of the device. |

# 11. Discussion

Based on the comparison information in our submission, we can determine that the subject device is similar to the predicate device in most aspect. The subject device has the same intended use, provided the same functions by the same operating principle as the predicate device, except housing and dimensions. The subject device has same material, design, technology, PCBA, software, electrode area and performance to

{6}------------------------------------------------

demonstrate these differences would not adversely impact the safety and effectiveness of the subject devices. The differences between the subject devices and the predicate device would not raise any problem in substantial equivalence claims.

# 12. Conclusion

After analyzing a series of non-clinical test results we have ensure that all of our design outputs meet the specified requirements of inputs, and also the final product meets the user needs. Thus, we can reasonably believe that the subject devices, HEATING TENS (FT-615), is substantially equivalent to the predicate device in safety and effectiveness.
