• Applicant: Bio-Medical Research Corp.
• Product Code: NGX · Physical Medicine
• Decision Date: Mar 23, 2007
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 890.5850
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

System from Slendertone is intended for use by healthy persons to apply trans-cutaneous electrical muscle stimulation (EMS) through skin contact electrodes. Indications for used are as follows: System-Abs, Type 390, E10/X10 - The improvement of abdominal muscle tone, for the strengthening of the abdominal 0 muscles and for the development of a firmer abdomen. System-Shorts, Type 390, E20 - Strengthening, toning and firming of the bottom and thigh region.

Device Story

System-Abs and System-Shorts are trans-cutaneous electrical muscle stimulation (EMS) devices for home use. The system comprises a garment (belt or shorts), a rechargeable handheld controller, and adhesive gel electrodes. The controller connects to the garment via a lead; an ID chip in the garment identifies the model and treatment parameters to the controller. The controller generates stimulation signals delivered to the skin via electrodes. The device offers 7 programs for the belt and 4 for the shorts. Power is provided by a 3.6V NiMH rechargeable battery. Users operate the device to exercise specific muscle groups; the controller interface allows program selection. The device is designed to prevent current from passing side-to-side and restricts user access to internal wiring to reduce misuse. Benefits include muscle strengthening and toning. The device cannot be used while charging.

Clinical Evidence

No new clinical studies were submitted. The manufacturer relies on clinical data previously submitted for predicate devices K010335 and K022855.

Technological Characteristics

EMS muscle stimulator; 3.6V NiMH rechargeable battery; handheld controller with garment-based ID chip; materials include Nylon, Elastane, Polyurethane, and Polyethylene. Safety testing per EN 60601-1, IEC 60601-2-10, and EMC standards (EN 60601-1-2, CISPR 22).

Indications for Use

Indicated for healthy persons seeking improvement of abdominal muscle tone, strengthening of abdominal muscles, development of a firmer abdomen, or strengthening, toning, and firming of the bottom and thigh region.

Regulatory Classification

Identification

A powered muscle stimulator is an electrically powered device intended for medical purposes that repeatedly contracts muscles by passing electrical currents through electrodes contacting the affected body area.

# 4. Description of Device

System-Abs and System-Shorts are the newest product offerings from Slendertone (division of Bio-Medical Research Ltd.). The products include an interchangeable, rechargeable handheld controller, which can be used with a garment from the System range, to exercise specific areas of the body. The System-Abs belt is used to exercise the abdominal muscles and the System-Shorts is used to exercise the bottom and thigh muscles.

{1}------------------------------------------------

The overall product consists of a garment (shorts for System-Shorts and belt for System-Abs), control unit, a pack of adhesive backed gel based electrodes (6 for System-Shorts and 3 for System-Abs), battery charger and instruction manual.

System is a two-channel EMS product and offers 7 programs to the user of the belt and 4 programs to users of the shorts. Electrodes are applied to the inner surface of the garment to cover the silver studs and the garment is fitted (sizing options are given for a best fit) using the hook and loop patches. Each System garment contains an ID chip, which is programmed to determine the different model types and treatment parameters and is connected to the electronic controller unit via a lead and connector. The control unit generates the required stimulation signals and the garment connects these signals to the skin electrodes. Power is derived from a 3.6V NiMH rechargeable battery pack that is pre-installed in the unit.

There is no current passed from side to side. Because the user has no access to the wiring or connectors within the garment, he/she cannot alter the current path and so the possibilities for misuse are greatly reduced.

The product cannot be used whilst in charge mode.
