Indications for Use

Slim UP® ULTRA is indicated for the use by healthy persons to apply transcutaneous electrical muscle stimulation (EMS) through skin contact electrode for the purpose of improvement of muscle tone of buttocks muscles.

Device Story

Slim UP® ULTRA is a powered muscle stimulator used in health spas and beauty salons. It applies transcutaneous electrical muscle stimulation (EMS) to the buttocks via 16 skin-contact electrodes. The device features 8 channels delivering a compensated two-phase rectangular waveform with 5-7 selectable multi-phase treatment programs. It includes an infrared (IR) unit with 6-7 lamps on a mobile arm for patient comfort; the IR component has no therapeutic effect. The device is operated by staff in a clinic setting. The system uses a microcontroller to manage stimulation parameters, intensity, and safety features, including an automatic shut-off and a safety circuit that resets the machine if current exceeds 100mA. The output is controlled by the operator via a control panel. By stimulating muscle contraction, the device aims to improve muscle tone, providing a non-invasive aesthetic benefit to the user.

Clinical Evidence

Bench testing only. Evidence includes biocompatibility testing per ISO 10993-1, electrical safety and EMC testing per IEC 60601-1, IEC 60601-1-2, and IEC 60601-2-10, and software verification and validation testing.

## Justification of predicate differences:

Differernce-1: Energy Source - IR source

Predicate device: Buttock muscle stimulator does not contain IR modality.

New Device: The Slim UP® ULTRA contains IR modality in addition to Electrostimulation modality.

Intended Use: Same

## Different questions of Safety and effectiveness? No

## Justification of Difference:

IR source does not have any therapeutic effect it is just used for patient comfort only. Also IR modality used in subject device is not able to raise and maintain body temperature above 38-41 degree Celsius for 10 minutes. IR source used in Slim UP® ULTRA is similar to reference device i.e. Syneron Medical's Velashape (K122579). So this minor technological difference does not raise any new questions of safety and efficacy.

## Difference-2: Physical Characteristics (Dimension and weight)

Predicate device: Buttock muscle stimulator is 0.08 Kg in weight and has physical dimensions of 64cm Width X20cm Diameter X90 cm Height.

New Device: The Slim UP® ULTRA has physical dimension of 95cm Width X 129cm Diameter X 187cm Height and 161 Kg in weight.

Intended Use: Same

# Different questions of Safety and effectiveness? No

## Justification of Difference:

The difference in physical dimensions and weight doesn't introduce any additional safety issues. Due to its compact size Slim UP® ULTRA can be located in any booth, can be adapted to any bed and can be moved anywhere.

{14}------------------------------------------------

## Difference-3: Housing material and construction

### Predicate device:

Buttock muscle stimulator has asbestos as primary housing material.

### New Device:

Different parts of Slim UP® ULTRA were made from different housing material. It has polycarbonate arc, nylon screw and washer for fixing the polycarbonate arc.

- Intended Use: Same
## Different questions of Safety and effectiveness? No Justification of difference:

This predicate difference will not raise any questions of safety and efficacy as patient body contact parts of Slim UP® ULTRA are biocompatible and Slim UP® ULTRA complies with international safety standard EN ISO 14121-1:2007- Safety of the equipment. Risk evaluation part-1: Principles.

## Difference-4: Number of electrodes

Predicate device: The information regarding number of electrodes in predicate device is not available.

New device: Slim UP® ULTRA has 16 skin contact electrodes.

Intended Use: Same

# Different questions of Safety and effectiveness? No

### Justification of difference:

The difference in number of electrodes do not raise new question of safety or effectiveness. Slim UP® ULTRA use 510k cleared electrode FIAB PG474W (K091163). Apart from this electromagnetic safety of subject device has been established by conducting EMC testing in complies with international EMC standard 60601-1-2 and 60601-2-10. So this difference will not raise any additional questions of safety and efficacy.

Difference-5: Functional parameters like Mode or Program name, Pulse duration, Number of output mode, pulse per burst, burst per second, Burst duration, Duty cycle, RMS current, Number of treatment program Method of channel isolation, Maximum current and power density.

### Predicate device:

Buttock muscle stimulator has following different functional parameters: Mode or Program name: WL-2413E Pulse Duration: 720 usec Number of output mode: 04 Pulse per burst: Same for each program Burst per second: Same for each program

{15}------------------------------------------------

Burst duration: Same for each program Duty cycle: Same for each program RMS current: 38.644mA (500Ω), 16.907mA (2KΩ), 5.120 mA (10 Ώ) Number of treatment program: N/A Method of Channel isolation: Output coil Maximum Current density: 0.0997 mA/cm2 Maximum Power density: 0.00399 watts/cm2

### New Device:

Slim UP® ULTRA has following different functional parameters:

Mode or Program name: 2 TONE (F2 work phase)

Pulse Duration: 400 usec

Number of output mode: N/A

Pulse per burst: 160

Burst per second: 1/8

Burst duration: 4 Sec

Duty cycle: 1/2

RMS current: 100mA during the active phase of the current pulse, square wave with null medium value and period of 600us

Number of treatment program: 7 different programs that should be chosen based on the individual requirements of each case.

Method of channel isolation: Sole transformer on all channels from 12V and the tension that goes to the electrostimulation channels (it is not an insulating transformer). If current goes over 100mA (short output transistor) a safety circuit intervenes by resetting the machine

Maximum current density: 2, 8 mA/cm2 @ 500Ω

Maximum power density: 8, 96 mW/cm² @ 500Ω with electrodes 4x9 cm

## Intended Use: Same

#### Different questions of safety and effectiveness: No Justification of difference:

The minor difference in functional parameter between predicate device and subject device do not raise new questions of safety or efficacy as Electromagnetic safety of Slim UP® ULTRA has been established by conducting EMC testing in complies with international EMC standard 60601-1. 60601-1-2 and 60601-2-10.

### Difference-6: Electrical Requirement

## Predicate device:

Runs on 3 AAA batteries at 1.5v. New Device: 230VAC, Single-Phase Intended Use: Same Different questions of Safety and effectiveness? No Justification of difference:

{16}------------------------------------------------

The difference in Electrical Requirements between predicate device and subject device do not raise new questions of safety or efficacy as Electromagnetic safety of Slim UP® ULTRA has been established by conducting EMC testing in complies with international EMC standard 60601-1, 60601-1-2 and 60601-2-10.

The conclusion of this technical comparison is that Slim UP® ULTRA is substantially equivalent to the Buttock Muscle Stimulator and have been verified by subsequent testing. Any difference between Predicate device and Slim UP® ULTRA do not raise any new questions for safety and efficacy.

## PERFORMANCE DATA

The following performance testing was provided in support of the substantial equivalence determination.

## Biocompatibility Testing

Patient applied parts of Slim UP® ULTRA are biocompatible as per the International standard ISO 10993-1:2009- Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process.

## Electrical safety and electromagnetic compatibility (EMC)

The following standards have been complied within designing, manufacturing and testing of Slim UP® ULTRA:

- IEC 60601-1:2012, Medical Electrical Equipment - Part 1: General Requirements for Safety.
- IEC 60601-1-2:2007, Medical Electrical Equipment Part 1-2: General ● Requirements for Safety - Collateral Standard: Electromagnetic Compatibility -Requirements and Tests.
