No
The document describes a standard neuromuscular electrical stimulator with Bluetooth connectivity and a mobile app for control. There is no mention of AI or ML algorithms being used for stimulation control, program selection, or any other function.
Yes.
The device is intended to stimulate healthy muscles to improve or facilitate muscle performance, specifically for the improvement of abdominal muscle tone, strengthening abdominal muscles, and developing a firmer abdomen, which are therapeutic benefits.
No
The intended use statement indicates that the device is for stimulating muscles to improve performance, tone, and strength, and not for diagnosing medical conditions. It is a neuromuscular electrical stimulator.
No
The device description explicitly states that the device includes a control unit, abdominal garment, and adhesive gel pads (electrodes), which are hardware components. While it utilizes a software app for control, it is not solely software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Device Function: The SLENDERTONE® connect Abs is a neuromuscular electrical stimulator. It works by applying electrical impulses to the abdominal muscles to stimulate them.
- Intended Use: The intended use is to stimulate healthy muscles to improve performance, tone, strength, and firmness. This is a physical intervention, not a diagnostic test performed on a sample.
The device description and intended use clearly indicate that it is a therapeutic or performance-enhancing device, not a diagnostic one.
N/A
Intended Use / Indications for Use
The SLENDERTONE connect Abs is intended to stimulate healthy muscles in order to improve or facilitate muscle performance. It is indicated for the improvement of abdominal muscle tone, for the strengthening of the abdominal muscles and for the development of a firmer abdomen.

Device Description
The SLENDERTONE® Connect Abs, Type 570 is a portable neuromuscular electrical stimulator intended to deliver electrical stimulation to the abdominal muscles. The device includes a control unit, abdominal garment, 3 adhesive gel pads (electrodes), USB cable and instructions for use. It contains one pre-installed program called 'Essential Toning'.
The SLENDERTONE® Connect Abs incorporates a Bluegiga BLE113 Bluetooth module to enable wireless communication and can be paired with a Bluetooth enabled iOS smart device running a Slendertone Connect iOS App, available from the Apple App store. The App implements a virtual control panel on the screen of the smart device where on-screen buttons are provided to the user.
The control unit is connected to the abdominal belt garment via an 8-pin interface. The control unit contains the primary controls for operation of the device and push buttons are available for switching the unit on or off and to increase or decrease the stimulation intensity. These controls remain active while the control unit is wirelessly paired with a smart device and can be used in the event of loss of Bluetooth connection. The SLENDERTONE® connect Abs contains light emitting diodes (LED) which indicate status relating to battery charge, stimulation and bluetooth activity. Power is derived from a 3.7V Li-Po rechargeable battery pack and the unit can be recharged by using the supplied USB cable.
The SLENDERTONE® Connect Abs, Type 570 is rated as IP22 for ingress protection. The user has no access to the wiring or connectors within the garment. For purposes of hygiene, the garment may be cleaned and instructions for garment care are included in the user manual.
