#### Device Description

truSculpt flex is an electrical muscle stimulator, which generates electrical impulses that are delivered through electrodes on the skin in direct proximity to the muscles to be stimulated. The device contracts muscles rhythmically to achieve the intended use of strengthening, firming, and toning the muscles of the abdomen, thighs, and buttocks.

truSculpt flex consists of a console with a touchscreen control panel and eight handpiece pairs. All system functions are controlled through the console. During a treatment session, one or more handpiece pairs are secured to the patient using disposable hydrogel pads and transparent silicone belts, and electrical stimulation is delivered to the treatment area at the selected treatment mode and intensity.

The fundamental scientific technology has not changed in the modified device. Changes are solely considered for ease of use for the clinicians. The modified device generates the same stimulation to contract the muscles rhythmically to achieve the intended use of strengthening, firming, and toning the muscles of the abdomen, thighs, and buttocks.

The clinician can increase or decrease the intensity as per the desired stimulation. While redesigning the device, complete care and considerable measures have been taken to retain its safety and effectiveness. The truSculpt flex device complies with voluntary standards.

The modified device, as described in this submission, is an upgrade from its previous version. Modifications include the addition of two outputs; change in electrode size and type; addition of adhesive hydrogel pads and reusable silicone belts; and renaming of treatment modes.

With respect to the previously cleared device, the modified device has two treatment types:

- > Classic In Classic mode, the treatment duration is 45 minutes.
- A flex+ - In flex+ mode, the treatment duration is 15 minutes.

For ease of use and operation for the clinicians, we have 3 modes (suggestive):

- . PREP mode creates a twisting motion to warm up and stretch the muscles and to slowly build a tolerance to muscle contractions. PREP mode is available for Classic treatments only.
Image /page/4/Picture/13 description: The image shows a diagram of a muscle being stimulated by two electrical devices. The devices are labeled with the numbers 1 and 2. The muscle is shown in a reddish-brown color, and the electrical stimulation is shown as yellow beams emanating from the devices. The devices are connected to the muscle by wires.

Fig:- Prep Mode

{5}------------------------------------------------

• TONE mode contracts the muscles, holds it, and then relaxes to increase strength and muscle endurance. TONE mode is available for Classic and flex+ treatments.

Image /page/5/Picture/3 description: The image shows a diagram of a muscle stimulation device. The device consists of two white pads with yellow tops, labeled "1" and "2", placed on a brown surface. Yellow beams are shown emanating from the pads, targeting a muscle underneath. The pads are connected to wires, with a red wire attached to pad "1" and a black wire attached to pad "2".

#### Fig:- Tone Mode

• SCULPT mode uses fast, sequential contractions of the muscles which leads to toning and firming. SCULPT mode is available for Classic and flex+ treatments

Image /page/5/Picture/6 description: The image shows a medical device used for muscle stimulation. Two white devices with yellow labels marked "1" and "2" are positioned above a muscle. Yellow beams are emitted from the devices, targeting the muscle below. The setup suggests a therapeutic or diagnostic application involving targeted muscle stimulation.

#### truSculpt flex in action- Interaction with patient

The device contracts muscles rhythmically to achieve the intended use of strengthening, firming, and toning the muscles of the abdomen, thighs, and buttocks.

Image /page/6/Picture/4 description: The image shows a person lying down with electrodes attached to their legs and abdomen. The electrodes are connected to wires that run to a machine in the background. The electrodes are placed on the person's skin with a clear plastic sheet. The electrodes are numbered 2, 3, 5, 6, and others.

#### Where

- 1. Reusable silicone belts (cummerbunds)
- 2. Electrodes ( Handpiece )
- 3. Adhesive hydrogel pads

The modified device generates electrical stimulation to contract the muscles rhythmically to achieve the intended use of strengthening, firming, and toning the muscles of the abdomen, thighs, and buttocks.

While redesigning the device, complete care and considerable measures have been taken to retain its safety and effectiveness. The truSculpt flex device complies with voluntary standards.

#### Intended Use

truSculpt flex is indicated to be used for:

- Improvement of abdominal tone, for strengthening of the abdominal muscles, for development of firmer abdomen.
- Strengthening, toning and firming of buttocks & thighs.

The device safety and efficacy was demonstrated by performance data and a comparison of technical characteristics between the modified device and the predicate device.

Substantial Equivalence- The intended use and indication for use of the modified device are the same as the predicate device (Torc Body , K192039).
