Indications for Use

The SCENAR Cutaneous Electrode Family with SCENAR TENS devices is indicated for relief and management of chronic and acute pain, as adjunctive treatment in the management of post-surgical and post-traumatic pain.

Device Story

SCENAR Cutaneous Electrode Family consists of passive add-on accessories (small, comb, and point electrodes) for RITM OKB ZAO transcutaneous electrical nerve stimulators. Electrodes interface with skin to deliver bipolar electric pulses generated by the host stimulator; no internal power or active circuitry. Used by medical professionals in clinical settings or by patients at home via physician prescription. Electrodes facilitate treatment of difficult-to-reach body areas (e.g., ulnar/wrist joints, feet, hairy regions, reflexogenic points) where built-in device electrodes are less effective. By enabling targeted stimulation, the device assists in pain management, potentially reducing reliance on other remedies. Output is non-invasive electrical stimulation; healthcare providers use the device to manage pain symptoms directly.

Clinical Evidence

Bench testing only. Performance testing characterized the electrodes against predicate InterX5000 accessories. Conformity to IEC 60601-1 (general safety), IEC 60601-2-10 (nerve and muscle stimulators), and IEC 60601-1-2 (EMC) was verified via test reports.

Technological Characteristics

Passive electrodes; materials include stainless steel, silver-plated brass, ABS plastic, and fluoroplastic. Configurations: coaxial bipolar (small, point) and multipoint bipolar (comb). Connectivity: wired connection to host TENS device via two-conductor cable. Non-sterile. No internal power or software.

Indications for Use

Indicated for relief and management of chronic and acute pain, and as adjunctive treatment for post-surgical and post-traumatic pain in patients requiring TENS therapy.

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.

Predicate Devices

• SCENAR (K092117)
• InterX5000 (K042912)

## 510(k) Summary

#### Submitter Information:

RITM OKB ZAO Address: 99, Petrovskaya str., Taganrog, Russia, 347900 Phone/fax: [phone] Contact person: Larisa Shpungina Date of Summary Preparation: May 19, 2014

#### Trade Name:

SCENAR (SCELAP, ENISAR, IPENS) Cutaneous Electrode Family

Common Name: Transcutaneous Electrical Nerve Stimulator

#### Classification Name:

TRANSCUTANEOUS ELECTRICAL NERVE STIMULATOR (21 CFR 882.5890, PRODUCT CODE GZJ)

#### Predicate Device:

SCENAR (K092117) InterX5000 (K042912)

#### Description:

The SCENAR Cutaneous Electrode Family is intended to be used with electrostimulation devices produced by RITM OKB ZAO as external add-on electrode accessories.

#### Purpose

Purpose of SCENAR transcutaneous electrostimulator (K092117) is completely specified. SCENAR transcutaneous electrostimulators and SCENAR Cutaneous Electrode Family are designed for delivering general non-invasive treatment via human skin areas for relief and management of chronic and acute pain, as adjunctive treatment in the management of postsurgical and post-traumatic pain.

SCENAR devices and SCENAR Cutaneous Electrode Family can be used:

- at home on a doctor's prescription to relief pain after various injuries and traumas;

- by medical professionals in medical and prophylactic institutions - as an independent remedy as well as combined with other treatments.

#### Action: How it works

SCENAR devices generate low and medium frequency bipolar electric pulses. The shape of the pulses dynamically varies with changing electrophysiological characteristics of the skin. The SCENAR Cutaneous Electrode Family has no power unless it is connected to transcutaneous electrostimulator. The SCENAR Cutaneous Electrode Family is placed

directly onto unbroken skin and does not use any conductive gels. These electrodes serve as complement to the device and allow influencing the special or hard-to-get-to parts of the body in comparison with built-in electrode.

The small electrode facilitates to influence parts with difficult relief -ulnar and wrist joints, feet etc. and also while using in pediatrics.

The comb electrode facilitates to influence pubis, axilla and other hairy parts of the skin. The point electrode allows carrying out condensed influence to reflexogenic points of extremities and ears.

#### List of produced devices

The SCENAR Cutaneous Electrode Family produced by RITM OKB ZAO is listed in the Table 1. The Electrodes are united into array since their purpose, application, mechanism of action, utilized materials, basic technical characteristics, functionality and manufacturing processes are similar.

The differences in dimensions of the subject and predicate devices are minor because:

- the dimensions of the electrode's part contacting the skin differ unsignificantly (2-5 mm). These dimensions are approximately determined by the purpose of the electrode and their minor deviations do not affect the Indications for Use and Fundamental scientific technology of the proposed electrodes;

- the third dimension (length) of the electrode has been determined considering ergonomics. This dimension as well as the shape of the electrode body can influence only the comfort of performing manipulations with the electrode, and maybe, the way the electrode is held.

SCENAR Cutaneous Electrode Family complies with performance standard requirements (21 CFR 898.12) relating to patient lead wires and electrodes.

RITM OKB ZAO has received test reports certifying that SCENAR Cutaneous Electrode Family was tested and found to be in conformity with IEC 60601-1, IEC 60601-2-10 and IEC 60601-1-2 international safety and EMC standards.

The test reports have been provided as part of this premarket notification. Test results of SCENAR devices with add-on electrodes (SCENAR Cutaneous Electrode Family) are given in the test reports.

#### Conclusions

The devices have intended use and technological characteristics that are substantially equivalent to those of the predicate device InterX5000 (K042912) (optional external electrode accessories) and SCENAR (K092117).

The test reports contained in this submission demonstrate that the submitted models are equivalent to the safety and effectiveness as that of the cleared devices.
