The Venus BlissMAX device using the FlexMAX applicators is intended to be operated by a trained professional #### 5. DEVICE DESCRIPTION The Venus BlissMAX device is a computerized system comprised of a system console (main unit), four (4) Diode Laser applicators, one (1) MP2 (RF+ PEMF+ Vacuum) applicator and four (4) FlexMAX (EMS) applicators. The system delivers laser, bipolar RF and biphasic electrical energies, vacuum pressure, and pulsed electromagnetic fields (PEMF) to the skin and the underlying tissues of the treatment area. The device provides individual adjustment of laser power, EMS intensity level, and RF power, in addition to vacuum levels, for each patient. The console of the Venus BlissMAX device contains a power supply unit, Laser, RF, and EMS controllers, (power modules, on main board), a suction module (vacuum), a controller unit (on main board), Laser water cooling system (power module, on main board), a touch- screen user interface and display panel. The applicators are connected to the console via a cable. The RF applicator is comprised of various combinations of RF electrodes, magnetic coils, and vacuum conduits. The Laser applicators are comprised of a light guide, touch sensors and light-emitting diodes. The EMS applicator is comprised of two electrodes and a light indicator. {5}------------------------------------------------ #### 6. TECHNOLOGICAL CHARACTERISTICS The Venus BlissMAX device delivers laser energy to the subcutaneous tissue layers via the four diode laser applicators connected to the console utilizes diode laser modules as sources of optical energy and the optical output is fiber-coupled through the applicator to the treatment area. The laser applicators are coupled to the patient's body while using a dedicated belt for the entire treatment. Individual adjustment of the laser output power is provided for each applicator to achieve maximum safety and efficiency for the patient. The laser applicators have an integrated contact skin cooling system to enhance safety and comfort of the treatment. In addition, the Venus BlissMAX device using the MP2 applicator provides RF treatments combined with emitted magnetic fields and vacuum massaging. The Vacuum is mainly used for the massaging of deep tissues by creating mild to deep suction. The vacuum massage improves the contact surface between electrodes and tissue. The RF currents heat the adipose and muscular tissues to trigger tissue level changes leading to temporary reduction in the appearance, of cellulite and temporary relief of muscle pain and muscle spasm. The RF heating effect also improves local blood circulation in the sub dermal layers. The PEMF assists in achieving treatment effect. Furthermore, The Venus BlissMAX device using the FlexMAX applicators (EMS applicators) contracts muscles by passing electrical currents through electrodes contacting the affected body area. The transcutaneous electrical current is designed to effect underlying, healthy muscles, causing them to contract. The FlexMAX applicators are coupled to the patient's body while using a dedicated belt during the entire treatment. The belt size and number of EMS applicators is determined by the treatment area and its size. Its use on muscles is in accordance with a class II device Powered Electrical Muscle Stimulator (Product Code NGX), based on the FDA guidance document for powered muscle stimulators for muscle conditioning as a special control1. ### 7.
