Non-invasive Lipolysis and Improvement of Muscle Tone in Lateral Abdomen

Simultaneous Application of High-Intensity Focused Electromagnetic Procedure and Radiofrequency for Non-invasive Lipolysis and Improvement of Muscle Tone in Lateral Abdomen

This study will evaluate the clinical efficacy and performance of the BTL-899 device for changes in subcutaneous fat and muscle tissue in the lateral abdomen region (also referred to as flanks or "love handles"). The study is a prospective, multi-center, open-label, single-arm study. The subjects will be enrolled and assigned into a single study group. Subjects will be required to complete four (4) treatment visits and two follow-up visits. All of the study subjects will receive the treatment with the subject device.

Study Overview

• Status: Completed
• Conditions: Fat Burn
• Intervention / Treatment: Device: BTL-899

Detailed Description

At the baseline visit, MRI imaging will be performed; the subject's weight and waist circumference will be recorded. Digital photographs of the treated area will be taken.

The treatment administration phase will consist of four (4) treatments, delivered 5-10 days apart. The applicators of BTL-899 will be applied over the area of flanks. The device will induce visible muscle contractions along with heating of the subcutaneous fat. Each therapy session will last 30 minutes.

At the last therapy visit, the subject's weight and waist circumference will be recorded, and digital photographs of the treated area will be taken. In addition, subjects will receive Therapy Comfort and Subject Satisfaction Questionnaire to fill in.

Safety measures will include documentation of adverse events (AE), which will be assessed after each procedure and at all of the follow-up visits.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Evaluation of change in adipose and muscle layer thickness; Evaluation of change in adipose and muscle layer thickness between pre-treatment and post-treatment based on MRI imaging and waist circumference measurements	Device: BTL-899; Treatment with applicators C4/C5 to the BTL-899 system.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Evaluation of change in adipose and muscle layer thickness	The changes in muscles and adipose tissue of the treatment area between pre-treatment and post-treatment will be evaluated according to the MRI imaging and waist circumference measurements. Using the obtained MRI images, changes in adipose and muscular tissues before and after the therapy sessions will be compared for every participant according to the study phase. The circumference before and after the study therapy will be compared for each subject, according to the study phase. The circumference will be measured to identify any change in abdominal circumference related to changes in adipose tissue and muscle thickness. When applicable, the statistical analysis will be conducted in Microsoft Excel spreadsheet software with a level of significance set to 5%.	4 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Subject Satisfaction	The 5-point Likert scale Subject Satisfaction Questionnaire will be used for an analysis of the subject's opinion of the therapy results, where the best possible answer would be "strongly agree" and the worst "strongly disagree".	4 months
