Intended Use

The AK Body Toning Device is intended for use by healthy persons to apply transcutaneous electrical muscle stimulation (EMS) through skin-contact electrodes in order to improve or facilitate muscle performance.

Device Story

Battery-operated, hand-held muscle stimulation system; intended for home use by healthy individuals. Device features rounded unit with handle and three rows of axels; two outer rows contain stainless steel powered electrodes; middle row contains plastic wheels for mobility. User applies electroconductive gel to skin; rolls device across treatment area (abdomen, thighs, buttocks). Device delivers monophasic, rectangular electrical pulses via electrodes spaced ~4 inches apart. Intensity adjusted via manual knob. Rolling electrode design allows stimulation of broader areas while potentially reducing skin burn risk compared to fixed-electrode systems. Output affects muscle performance through induced contraction. No software or microprocessor control.

Clinical Evidence

Bench testing only. Study used ultrasound imaging to observe and compare anterior thigh muscle movement during stimulation between subject and predicate devices; results showed similar muscle stimulation performance. Biocompatibility testing performed per ISO 10993. Electrical safety and EMC testing conducted per IEC 60601-1, IEC 60601-1-2, UL 60601-1, CSA C22.2 No. 601.1, and IEC 60601-2-10.

Technological Characteristics

Battery-operated (3 x 1.5V AAA); monophasic rectangular waveform; manual intensity control. Housing material: ABS. Electrodes: stainless steel. Dimensions: 3.12 x 3.51 x 7.0 inches. Weight: 800g. Standards: IEC 60601-1:2005, IEC 60601-1-2:2007, UL 60601-1, CSA C22.2 No. 601.1, IEC 60601-2-10:2012. No software, firmware, or microprocessor control.

#### II. DEVICE

Name of Device: AK Body Toning Device Common or Usual Name: Muscle Stimulation Device Classification Name: Powered Muscle Stimulator for Muscle Conditioning Regulatory Class: 21 CFR 890.5850, Class II Product Code: NGX

#### lll. PREDICATE DEVICE

- . K083140; Compex Sport Plus manufactured by DJO, LLC
These predicates have not been subject to a design-related recall. 2

No reference devices were used in this submission.

#### IV. DEVICE DESCRIPTION

The AK Body Toning Device is a battery-operated, hand-held, single-program, muscle stimulation system to tone healthy muscles of the abdomen, thighs, and buttock. The device is self- contained with three rows of axels under a rounded unit with a handle that is shaped to allow a comfortable hand-grip for the user. Each axel has three knobbed wheels. The two sets of stainless on the ends are the powered electrodes and the middle set of plastic wheels allows for easier movement across the skin.

The device produces transcutaneous electrical muscle stimulation through the powered electrodes that are approximately four inches apart. An on-off switch applies the power and an adjustable knob sets the intensity of the treatment. An electroconductive gel is applied to the skin in the area to be treated and the device is rolled across the treatment area. The knob is adjusted until the treatment is effective and may be increased after initial use.

#### V. INDICATIONS FOR USE

The AK Body Toning Device is intended to for use by healthy persons to apply transcutaneous electrical muscle stimulation (EMS) through skin-contact electrodes in order to improve or facilitate muscle performance.

#### VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

¹ On July 9, 2012, section 605 of FDASIA (Pub. L. 112-144) added section 518A to the FD&C Act, which directs FDA to establish a program to routinely and systematically assess information regarding device recalls, and to use that information to proactively identify strategies for mitigating health risks presented by defective or unsafe devices. FDA believes that one way to carry out this directive is to provide greater transparency on recalled devices. Identifying whether a predicate was recalled is optional, but doing so would help the Agency achieve this FDASIA directive.

{4}------------------------------------------------

The AK Body Toning Device is substantially equivalent to other legally marketed muscle stimulation devices cleared under product code NGX. The intended use of the AK Body Toning Device is the same as the predicate devices. All are intended for use on healthy muscles to improve muscle tone and are not intended to treat any diseases and are contraindicted for use on unhealthy muscles.

The AK Body Toning Device uses the same electrical stimulation principals as the predicate device. The AK Body Toning Device delivers the stimulation through rolling electrodes versus fixed electrodes in the predicate devices. However, the basic unit characteristics and output specifications of the AK Body Toning Device are substantially equivalent to the predicate devices. The rolling electrodes do not raise any new questions of safety or effectiveness. On the other hand, because the electrodes are moved across the treatment area and do not stay in one place, the AK Body Toning Device provides and extra measure of safety from consequences like skin burns, while effectively delivering electrical stimulation to a broader area during a treatment session. Thus, the AK Body Toning Device is substantially equivalent to existing predicate devices with the NGX product code.

#### VII. PERFORMANCE DATA

The following performance data were provided in support of the substantial equivalence determination.

### Performance testing

A study observed muscle movement by ultrasound imaging. Real-time stimulation of the anterior thigh muscle was recorded using the AK device (while being held stationary and while being rolled) and the predicate device. The muscle stimulation was similar for the AK Body Toning Device and the predicate device.

### Biocompatibility testing

The biocompatibility evaluation for the skin contact materials used in the AK Body Toning Device was conducted in accordance with the FDA Blue Book Memorandum #G95-1 "Use of International Standard ISO-10993, 'Biological Evaluation of Medical Devices Part 1: Evaluation and Testing," May 1, 1995, and International Standard ISO 10993-1 "Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by FDA.

# Electrical safety and electromagnetic compatibility (EMC)

Performance and electrical safety testing were conducted on the AK Body Toning Device. The test results demonstrate that the device safely performs as intended and raised no new questions of safety or performance compared to the predicate devices. Internationally recognized standards include:

- . IEC 60601 1: 2005 + CORR. 1 (2006) + CORR. 2 (2007) + AM1 (2012)
- . IEC 60601-1-2:2007 (Third Edition)
- UL 60601-1 (2003)
- . CSA C22.2 No. 601.1 (2003)
- IEC 60601-2-10: 2012 (Second Edition) ●

#### VIII. CONCLUSIONS

The AK Body Toning Device is substantially equivalent the predicate device. They both are intended to stimulate healthy muscles to improve or facilitate muscle performance. They stimulate the muscles by delivering electrical current through electrodes to the skin to cause muscle contraction. The predicate is indicated for several muscle groups but the AK Body Toning Device is limited to the abdomen, buttocks and thighs. Their technological characteristics differ in that the AK Body Toning Device uses rolling electrodes but the predicate device uses fixed electrodes. The data indicates that the AK Body toning Device works as safely and effectively as the predicate device.
