Intended Use

This device is a prescription device and only for symptomatic relief of chronic intractable pain. Relaxation of muscle spasms. Prevention or retardation of disuse atrophy. Increasing local blood circulation. Muscle re-education. Immediate post-surgical stimulation of calf muscles to prevent venous thrombosis. Maintaining or increasing range of motion.

Device Story

Digi-Pro TENS series (WL-2203, WL-2204, WL-2205) are transcutaneous electrical nerve/muscle stimulators. Device consists of a microprocessor-controlled stimulus generator and electrodes attached to patient skin. Generator produces adjustable electrical waveforms/currents based on controller input. Used for pain relief and muscle stimulation. Operated by patients or clinicians. Output affects nerve/muscle tissue to provide therapeutic benefits like pain management, spasm reduction, and circulation improvement.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Microprocessor-controlled electrical stimulator; output current delivered via skin-surface electrodes; adjustable waveform and output parameters; software-controlled operation modes.

Indications for Use

Indicated for patients requiring symptomatic relief of chronic intractable pain (TENS function) or muscle stimulation for relaxation of spasms, prevention/retardation of disuse atrophy, increased local blood circulation, muscle re-education, immediate post-surgical calf muscle stimulation to prevent venous thrombosis, and maintenance/increase of range of motion (EMS function).

Regulatory Classification

Identification

A transcutaneous electrical nerve stimulator for pain relief is a device used to apply an electrical current to electrodes on a patient's skin to treat pain.

- 2. Name of the Device:
Well-Life TENS (Transcutaneous Electrical Nerve Stimulation Device), Model Digi-Pro TENS series, including WL-2203, WL-2204, and WL-2205.

- 3. Information of the 510(k) Cleared Device (Predicate Device): Please see the information provided in part 6 of this summary.
## 4. Device Description:

The Digi-Pro TENS series, including WL-2203, WL-2204, and WL-2205 are transcutaneous r he Dig TTO reason of sed for pain relief and/or powered muscle stimulator by applying an electrical norrent to electrodes, which are attached on the patient's skin. The output and waveform is adjustable according to the situation of patient.

Digi-Pro TENS series, models WL-2203, WL-2204, and WL-2205, consist mainly of two parts: Digit to TENO benerator, electrode. The stimulus generator generates the output current specified the input of controller. The output port transmits the output current to the electrode, which is attached to the patient's skin so as to transmit this stimulus current to the patient for pain relief.

The stimulation mode for Digi-Pro TENS includes several different operation modes as mentioned on the comparison table. These operation modes are generated from the software control by using the microprocessor as its main control unit.

### 5. Intended Use:

On the instruction manual of each model, the intended uses and contraindication are defined very clearly. Please see the information of instruction manuals in clause 7.6 of this submission document.

In addition, the standard format for the statement of indications and contraindication for use are provided hereafter.
