A Clinical Evaluation of a Next Generation, Non-Invasive, Selective Radiofrequency, Hands-Free, Body-Shaping Device

Area of Science:

• Dermatology
• Medical Devices
• Body Contouring

Background:

• Noninvasive selective radiofrequency (RF) devices are used for body contouring.
• The BTL Vanquish METM is a redesigned RF system for improved energy delivery.
• Comparing its efficacy to the previous VanquishTM device is important for clinical understanding.

Purpose of the Study:

• To compare the clinical outcomes of BTL Vanquish METM with its predecessor, VanquishTM.
• To evaluate the efficiency, predictability, and homogeneity of energy delivery.
• To assess the fat reduction efficacy of both devices.

Main Methods:

• A multi-center study involving 36 subjects with BMIs under 30.
• Random assignment into two groups: BTL Vanquish METM (Group A) and VanquishTM (Group B).
• Four weekly 45-minute treatments, with abdominal fat measurements taken before and four weeks after the final treatment.

Main Results:

• BTL Vanquish METM (Group A) achieved a 29.46% (4.17 mm) reduction in abdominal fat thickness, compared to 15.21% (2.72 mm) for VanquishTM (Group B).
• Group A showed a 53% greater fat reduction than Group B.
• Calculated average fat volume reduction was 0.876 liters for Group A and 0.571 liters for Group B.

Conclusions:

• BTL Vanquish METM demonstrated statistically significant superior outcomes compared to VanquishTM.
• The reduced standard deviation in fat reduction measurements indicates more consistent performance with Vanquish METM.
• The study supports Vanquish METM as a more effective noninvasive fat reduction device.
