Indications for Use
The iRelieve Microcurrent Pain Relief System is intended to be used by physicians or licensed practitioners for symptomatic relief of chronic intractable pain.
Device Story
iRelieve Microcurrent Pain Relief System is a single-channel microcurrent TENS device; delivers electrical impulses through skin to underlying nerves to block pain signals. Device consists of a portable unit powered by a 3V coin cell battery; snaps onto 1-piece or 2-piece electrodes. Operation is fully automated via embedded firmware; no user-adjustable output controls; device activates upon switching on after electrode application. Firmware executes a preprogrammed four-hour routine cycling through DC+, DC-, AC, and Off modes; repeats until device is powered off or removed. Healthcare providers apply device to patient; output intensity varies between 15-30uA under firmware control. Benefits include non-invasive symptomatic pain relief for chronic intractable conditions.
Clinical Evidence
No clinical data. Evidence consists of bench testing, including output performance measurements (oscilloscope captures at 500, 2K, and 10K Ohms), electrode dispersion/impedance/adhesive/conformability testing, shelf-life, packaging (ASTM D4169-16), and battery life. Biocompatibility leveraged from predicate electrodes (K070807).
Technological Characteristics
Polycarbonate housing; 1-channel bipolar output; 3V CR2032 battery. Microcurrent output: 15-30uA, max 3.0V. Waveforms: DC+, DC-, AC (square). Frequency: 3-909 Hz. Connectivity: None.

## Device Description
The iRelieve Microcurrent Pain Relief System is a microcurrent TENS device that operates by sending electrical impulses through the skin to the nerves lying directly beneath the skin surface. These impulses help block the body's ability to send a pain message to the brain, thereby reducing the pain sensation. The iRelieve Microcurrent Pain Relief System is a single channel device that produces microampere currents with the selected envelopes, waveforms, frequencies, and polarity, with a maximum voltage of 3.0 volts. It is controlled by analogue electrical parts (voltage regulator, frequency oscillator, multiple resistors, etc.) and a digital microprocessor chip that contains embedded programmed software (firmware) that generates a sequence of current flows and frequencies during the course of a single treatment session. The iRelieve Microcurrent Pain Relief System performs this sequence of current flows without user manipulation or device controls other than switching the device on after application of the device to the electrodes.
#### Electrodes
The device is snapped onto one of two electrode designs. One is a 1-piece electrode designed for use on the back along the spine. The other electrode is a 2-piece design that can be used on other areas of the body, including joints and extremities.
The electrodes are identical in materials to the electrodes cleared under K070807. Both electrodes are stamped out using a die stamp composed of the same material. Both are manufactured by Pepin Manufacturing, Inc. The only different between the electrodes cleared under K070807 and the electrodes in this submission are shape. Relevant testing including Electrode Dispersion and Impedance Testing, Adhesive Testing, Electrode Cord Pull Testing, Fluid Tolerance Testing, and Conformability Testing was conducted to account for this difference.
#### Indications
The iRelieve Microcurrent Pain Relief System is intended to be used by physicians or licensed practitioners for symptomatic relief of chronic intractable pain.

### Discussion of differences
While the subject device only contains one device model, the predicate device contains three separate models of the device with each model containing different output modes. The subject device is Substantially Equivalent in device output to one of these versions, the Model 7500 Microcurrent TENS Device, Version MCT-F50. The premarket notification provided a device description in sufficient detail to demonstrate substantial equivalence to the predicate device.
#### Conclusion
The iRelieve Microcurrent Pain Relief System and the predicate device have the same intended use and similar technical characteristics, performance and applications. The information supplied in the full 510(k) application illustrates that the device does not pose any new question of safety or effectiveness. The iRelieve Microcurrent Pain Relief System is substantially equivalent to the predicate device.
