Intended Use

System-Mini, Type 390, Model E30 is intended for use by healthy persons to apply transcutaneous electrical muscle stimulation ("EMS") through skin contact electrodes for the purpose of exercising the gluteal muscles. Proposed indications for use are: Strengthening, toning and firming of the bottom. System-Mini, Type 390, Model E30 is intended for over-the-counter use.

Device Description

System-Mini, Type 390, Model E30 is a two-channel, battery powered muscle stimulation system. It consists of a skirt-shaped garment which is available in small (24-38"), medium (36-45") and large (40-48") sizes for best fit, a pack of 4 electrodes and instructions for use and is used with the Slendertone® System rechargeable handheld control unit which may be purchased separately or used from an existing Slendertone® System device i.e. System-Abs, Type 390, E10/X10 or the predicate System-Shorts, Type 390, Model E20. The four equal sized electrodes (6 cm x 15 cm) are attached to the inner surface of the garment to cover stainless steel studs by using the electrode outlines to ensure correct placement. The garment is connected to the control unit by a lead and an over-molded SATA 7-pin connector, which incorporates an EEPROM (ID chip) device. As with the predicate System-Shorts, the ID chip contains the data that identifies the garment type and the stimulation parameters intended for that garment. The model number of the garment itself is displayed on the LCD at power-on and on a label on the garment. When the control unit is connected to the garment, the data is read, identifying the specific garment type and also the stimulation parameters. The appropriate signals are then delivered to the garment electrodes. There are four programs in total available to the System-Mini user and these are designated as "beginner", "intermediate", "advanced" and "expert". All internal connections are over-molded to prevent moisture ingress. The user has no access to the wiring or connectors within the garment and is unable to alter the current path. Power is derived from a 3.6V NiMH rechargeable battery pack that is pre-installed in the unit. As with the predicate System-Shorts, System-Mini cannot be used when in charge mode. For purposes of hygiene, the garment may be cleaned and instructions for belt care are included in the user manual.

AI/ML (Artificial Intelligence / Machine Learning)

No
The document does not mention AI, ML, or any related concepts like training data, test data, or complex algorithms that would suggest the use of AI/ML. The device description focuses on hardware components and pre-defined stimulation parameters.

Therapeutic

No
The device is intended for healthy persons for exercising, strengthening, toning, and firming muscles, which are not considered therapeutic indications.

Diagnostic

This device is intended for transcutaneous electrical muscle stimulation for exercising, strengthening, toning, and firming muscles, not for diagnosing any condition.

SaMD (Software as a Medical Device)

The device description clearly outlines hardware components including a garment, electrodes, a control unit, a lead, a connector with an EEPROM chip, and a battery pack. It is a physical electrical muscle stimulation system.

IVD (In Vitro Diagnostic)

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

Intended Use: The intended use is to apply transcutaneous electrical muscle stimulation for exercising the gluteal muscles, specifically for strengthening, toning, and firming. This is a physical therapy/exercise application, not a diagnostic test performed on biological samples.
Device Description: The device is a muscle stimulation system that delivers electrical signals through electrodes applied to the skin. It does not involve the analysis of any biological specimens (like blood, urine, tissue, etc.).
Lack of IVD Characteristics: The description does not mention any components or processes typically associated with IVDs, such as reagents, assays, sample collection, or analysis of biological markers.

Therefore, the System-Mini, Type 390, Model E30 is a therapeutic or exercise device, not an in vitro diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

No new clinical studies have been submitted as part of this Premarket Notification.

Slendertone System has been independently tested to the following requirements:

EN 60601-1-2:2001 Medical electrical equipment Part 1-2: General requirements for safety - Collateral standard: Electromagnetic compatibility - Requirements and tests (IEC 60601-1-2:2001).
CISPR 22:2003 Information technology equipment Radio disturbance characteristics - Limits and methods of measurement & CFR 47 Part 15:2005 -Radio Frequency Devices.
DIN EN 60601-1:1996; EN 60601-1:1990+A1:1993 +A2:1995 Medical electrical c equipment - Part 1: General requirements for safety
IEC 60601-1:1988, IEC 60601-1/A1:1991, IEC 60601-1/A2:1995
DIN EN 60601-2-10 Medical electrical equipment Part 2-10: Particular requirements for the safety of nerve and muscle stimulators, IEC 60601-2-10
Battery Charger complies to safety standards IEC 60950 and UL 1950

Both the proposed System-Mini and predicate System-Shorts use identical electronic hardware. The principal physical difference is that the proposed System-Mini device omits two electrodes of the predicate device, which were located over the quadriceps. The electrical output into the body, as measured by the rms current is comparable. Likewise, the maximum current density at the electrodes is less than or equal to the predicate device. Therefore, no new safety issues arise with the proposed device.

The predicate device, System Shorts was shown to be effective for the improvement of strength, firmness and tone of the bottom and thigh muscles. The proposed device, System Mini, delivers effective gluteal component of the therapy.

Dear Ms. Keenan:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
