Dear Michael Treas:

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. 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.

#### 5.2 Device Description

The second-generation WiTouch Pro (a.k.a. WiTouch/Neubac) device is a battery powered transcutaneous electrical nerve stimulator (TENS) device for relieving back pain. The device is comprised of a TENS generator with integral electrodes, two replaceable "AAA" size batteries, replaceable electroconductive hydrogel pads (Gel Pads), a Mobile App to control the TENS device via Bluetooth® connection, which installs to Apple® iOS® 9.0 or higher or Android® 4.4 or higher smartphone platforms. Additionally, the TENS intensity may be increased or decreased using onboard mechanical buttons on the TENS unit enclosure. The TENS device offers an optional handheld wireless remote control via Radio Frequency (RF) connection which is sold separate and comes with one replaceable CR2032 Lithium-ion coin battery.

The device accessories are the replaceable Gel Pads, the Mobile App, and the optional wireless handheld remote control. The Gel Pads serve to gently adhere the TENS unit to a user's skin on the lower back, and serves to dissipate electrical stimulation across the surface area of the electrode. The Gel Pads are intended for single person use with the number of uses dependent upon skin type, oils, and pH levels.

The TENS unit adheres to the user's lower back across the spine in the area where pain is perceived. Once placed, a user can choose from four 30-minute preprogrammed stimulation output modes, and the level of intensity that is most comfortable. The preprogrammed modes are identified as WiTouch Pro Exclusive, High Frequency, Low Frequency, and High-Low Combo.

Accessories:

- Pairs of replaceable hydrogel pads (Gel Pads) ●
- Mobile Medical Application control using a smartphone via Bluetooth® ● connection (Apple® iOS® or Android® platforms)
- Handheld wireless Remote Control.

#### 5.3 Intended Use

The intended use is to provide approximately thirty minutes of analgesic electrical stimulus to reduce the perception of pain by electrically stimulating peripheral nerves across healthy intact skin of the lower back.

#### 5.4 Indications for Use

To be used for temporary relief of pain associated with sore and aching muscles in the back due to strain from exercise or normal household and work activities and relief of pain of the upper and lower back associated with arthritis.

#### 5.7 Conclusion

The basis for substantial equivalence for the referenced predicate device and for the second-generation WiTouch Pro TENS device is non-clinical data and conformity with recognized standards.

Clinical testing was not required to support substantial equivalence for the secondgeneration WiTouch Pro TENS device. This is due to the intended use is well established and understood, and the hardware and software verification and validation demonstrate that the second-generation WiTouch Pro TENS device performs comparably to the predicate device that is marketed for the same intended use.

Based on the performance testing and the similarities of the indications for use and the technological characteristics, it can be concluded that the second-generation WiTouch Pro TENS device is as safe and effective as, and substantially equivalent to, the predicate device.
