The device description and performance studies focus on electrical muscle stimulation and a comparison to a predicate device using the same technology platform. There is no mention of AI, ML, or related concepts.
No
The device is described as a "muscle stimulation system specifically designed to exercise the abdominal muscles" for "improvement of abdominal muscle tone, for strengthening of the abdominal muscles and for the development of a firmer abdomen," which aligns more with a fitness or cosmetic purpose rather than treating a disease or condition.
No
The device is described as a muscle stimulation system intended for improving muscle tone and strengthening muscles, not for diagnosing conditions or diseases.
No
The device description explicitly states it comprises two main components: an electronic stimulator module and an abdominal electrode belt, both of which are hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the improvement, strengthening, and development of abdominal muscles. This is a physical effect on the body, not a diagnostic test performed on samples taken from the body.
- Device Description: The device is a muscle stimulation system that applies electrical current to the skin to stimulate muscles. This is a therapeutic or physical conditioning device, not a diagnostic one.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting biomarkers, or providing diagnostic information about a disease or condition.
IVD devices are used to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. The Slendertone Gymbody does not fit this description.

Device Description
Slendertone Gymbody, Type 512-01 is a two-program battery operated muscle stimulation system specifically designed to exercise the abdominal muscles. It is a variant of Slendertone Flex, Type 512 abdominal training system and was developed to provide a lower cost alternative to the consumer.
It comprises of two main components, an electronic stimulator module, which generates the required stimulation signals, and an abdominal electrode belt, which connects the signals from the stimulator to the skin electrodes located on the inner surface of the belt.
The product is supplied with a set of double-sided adhesive electrodes, an instruction manual and a set of batteries. Power is derived from 1 x 9volt battery located in a compartment protected by a removable battery cover.
The 3 pads are attached to the belt covering the 3 metal studs on the inner surface of the belt. The larger pad is placed in the middle, over the umbilicus, and the two side electrodes are located on either side of the body towards the mid axillary line, between the pelvis and the rib cage.
The pulsed stimulation current passes between the side and center electrodes only. There is no current passed from side to side.

- న. Technological Comparison
Slendertone Gymbody is a variant of the Slendertone Flex Abdominal Training System and is a lower cost alternative to the consumer. It has been designed to differ visually from the original device while remaining compliant with all necessary legislative and performance standards. The device's intended use or fundamental scientific technology does not differ from Slendertone Flex, Type 512 (K010335).
Design
Slendertone Gymbody, Type 512-01, is a two channel, three electrode, battery operated muscle stimulation system comprising of two main components, the electronic stimulator module and the electrode belt. The device uses a set of adhesive electrodes to transfer stimulation signals to the skin. This is the same as Slendertone Flex, Type 512.
Slendertone Gymbody, Type 512-01 is a 2 program device whereas Slendertone Flex, Type 512 is a 4 program device. The 2 program levels (1 & 2) are the same as levels 2 and 4 in Slendertone Flex, Type 512.
Slendertone Gymbody, Type 512-01 contains a different user interface from its predicate device Slendertone Flex, Type 512. The LCD user interface present in Slendertone Flex, Type 512 has been changed to a series of LEDS. There is no significant change to the internal control mechanism and principles of operation remain the same. Visual indication of status and functionality are different however and are reflected in the instructions for use. The changes do not impact on the safety or efficacy of the device.
Slendertone Gymbody, Type 512-01 contains a different housing and keypad format from Slendertone Flex, Type 512 . The changes do not impact upon safety or efficacy of the device nor do they impact on indications for use. The fundamental operating principle remains the same.

Section 8: Design Control
Risk Management.
A risk analysis was carried out during the design phase of the previously marketed device, Slendertone Flex, Model 512. Since then, the procedure for Risk Management in the company has been upgraded to reflect the requirements of ISO 14971. This new procedure has now been applied to the proposed modified device Slendertone Gymbody Model 512-01 and the full analysis is on file.
Summary of Changes
In this summary we highlight the modifications to the product from the standpoint of risk.
Replacement of LCD by LEDs
All major display functions of the LCD are implemented on the LEDs, except;
The treatment is digitally timed however the time is not displayed. No safety or efficacy issue is raised since the timer display is a convenience indicator to inform the user on the remaining treatment time.
The stimulus intensity is not digitally displayed, instead 3 LEDs are used to represent 4 levels of stimulation. The stimulus intensity is incremented in 1% steps with each keypress, as it was on the previously marketed device. No safety or efficacy issue is raised here because the stimulus intensity setting is determined by the user's comfort and tolerance level, not by prescription of any particular intensity level. The digital display is a convenience indicator to inform the user about the intensity level they have reached.
Removal of Audible feedback.
The audio indicator was used in the predicate device to provide audio feedback beeps with each keypress and to alert the user when the load sense circuit detected no load. This is a convenience issue with no safety issue since the intensity is reduced to effectively zero when no load is detected. In any case, there was an audio mute function on the predicate model.
Removal of EEPROM
The EEPROM only stored user statistics and preferences on the predicate device, not treatment data. No safety or efficacy issue arises with its removal.
Change to a single amplitude control.
The predicate device has a separate left and right intensity control. however the new device has a single control which controls both left and right. The product is intended to stimulate the abdominal muscles symmetrically, that is, approximately equally on the left and right sides. The predicate device already had a software control which prevented the user selecting gross asymmetry in left and right intensity. No safety or efficacy issue is raised by this change.
4
Change of battery type.
No safety or efficacy issue arises.
Removal of two programs.
The main working program of the new product, program 2 is identical to program 4 of the predicate device. The other programs have been included to introduce users to the sensation of EMS, with slightly shorter contraction times. No safety or efficacy issue arises.
Change to style of Belt
The spacing, size and design of electrodes are identical so no safety or efficacy issue arises.
Change to Connector linking Controller and Belt
The connector design has changed from an audio jack and socket to an industrial wire to board connector. The connector in the new product is perhaps less convenient to use however it provides the same or greater protection. The arrangement also been certified for compliance to the ISO 60601 standards. Furthermore, since the leadwires are integrated within a belt, the risk is negligible.
A declaration of conformity to design control is included in Appendix 3
