No
The device description and performance studies focus on standard TENS technology and electrical/biocompatibility testing, with no mention of AI or ML.
Yes.
The device is intended for the temporary relief of pain associated with sore and aching muscles, which classifies it as a therapeutic device.
No
The device is described as a TENS device intended for temporary pain relief, not for diagnosing medical conditions.
No
The device description explicitly states it is a "9V battery operated TENS device" and includes physical components like electrodes and a main device part, indicating it is a hardware device with potentially embedded software, not a software-only medical device.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "temporary relief of pain associated with sore and aching muscles in the upper and lower extremities (arm and/or leg) due to strain from exercise or normal household and work activities." This describes a therapeutic purpose, not a diagnostic one.
- Device Description: The device is described as an "OTC TENS" (Transcutaneous Electrical Nerve Stimulation) device. TENS devices are used for pain relief by applying electrical stimulation to the body. This is a physical therapy modality, not an in vitro diagnostic method.
- Lack of Diagnostic Activity: The description focuses on the electrical stimulation parameters, electrodes, and how the device is worn. There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or providing information about a disease or condition based on such analysis, which are hallmarks of IVD devices.
Therefore, the LIFECARE Arm & Leg Pain Relief System, model EV-820 is a therapeutic device, specifically a TENS device, and not an In Vitro Diagnostic device.

Device Description
The LIFECARE Arm & Leg Pain Relief System, model EV-820 is the model of OTC TENS intended for temporary relief of pain associated with sore and aching muscles in the upper and lower extremities (arm and/or leg) due to strain from exercise or normal household and work activities. Basically the stimulation model EV-820 is completely identical to that of model as mentioned in our previous submission of Everyway Low Back Pain Relief System, model EV-820(K110716). To change the indication for use for the treatment location as the chosen predicate devices, Everyway changed the design of electrode.
For the device included in this submission, we use the following of our 510(K) legally marketed predicate garment electrodes and self adhesive electrode:
K103716, "Lifecare HC-88 Series Conductive Garments" together with our Lifecare TKF4080( 4x8 CM )/K083302 self adhesive electrode.
EV-820 is a selectable dual channel, 9V battery operated TENS device with the following features:
- The operation function is dual channels completely identical to the model being modified, EV-820 for low back pain relief(K110716).
- For the stimulation electrode, LIFECARE Arm & Leg Pain Relief System, model EV-820 uses our K103716 " Lifecare HC-88 Series Conductive Garment Electrodes" together with our Lifecare TKF4080( 4x8 CM )/K083302 self adhesive electrode as standard accessories.
- The output waveform is selectable pre-programming change among P1~P8.
- The output strength is adjustable at 0~80 mA, with maximum setting time 60 minutes counting from switching ON.
- The LCD display is provided for the indication of operation status including operation mode, output program mode, output intensity, time to cut-off, and battery low warning.
With the combination of the main device parts, the device can be worn on the Arm & Leg part of user so as to place the stimulation pads on the treatment location of Arm & Leg for over the counter use without prescription in temporary relief of pain associated with sore and aching muscles in the Arm & Leg.

7. Comparison to the 510(k) Cleared Device (Predicate Device):
For the substantial equivalent comparison, the power level testing comparison with the chosen 510(K) cleared device, Prizm 5000-Z system and Well Life WL-2407, was conducted via using 1K ohm loading resistance for the garment electrodes. The comparison result is as the following table:
| Electrode Type | Glove | Sleeve& Knee | Sock |
|---|---|---|---|
| Everyway EV-820 | 0.00337 | 0.00386 | 0.00271 |
| Well-life WL-2407 | 0.00337 | 0.00386 | 0.00271 |
| Prizm 5000-Z | 0.00340 | 0.00385 | 0.00274 |
Current Density comparison: (Unit : mA/cm2 )
Power Density Comparison : (Unit : W/cm2 )
| Electrode Type | Glove | Sleeve & Knee | Sock |
|---|---|---|---|
| Everyway EV-820 | 0.00032 | 0.00036 | 0.00025 |
| Well-life WL-2407 | 0.00032 | 0.00036 | 0.00025 |
| Prizm 5000-Z | 0.00064 | 0.00072 | 0.00051 |
Based on this comparison result, we made a acknowledge that our EV-820 model has the same output level as that of WL-2407, but has a lower current and power density than that of Prizm 5000-Z system while using the same electrode. This result is completely similar to the comparison of WL-2407 and Prizm 5000-Z system. Therefore; we concluded that the Everyway Arm & Leg Pain Relief system is substantially equivalent to Well-Life WL-2407(K091757) and the Prizm 5000-Z system (K033122) in the feature of stimulation output characteristics.
