This is an open-label, evaluator-blind study of the safety and performance of radiofrequency (RF) and pulsed electromagnetic field (PEMF) therapy following liposuction. The study will enroll up to 50 male and female subjects requesting treatment of the back, flanks and/or thighs to improve appearance following liposuction. Subjects will receive a total of six study treatments to one side of their body (back, flanks and/or thighs) at one week intervals. Subjects will be followed up at one month after their last study treatment. Treatment outcomes will be compared to the non-treated side.', 'detailedDescription': 'Adipose tissue is a loose type of connective tissue specialized to store lipids. The majority of lipids stored in adipose cells are triglycerides formed from imported free fatty acids and glycerol. It is not uniformly distributed in the body. The major adipose depot is subcutaneous (about 80% of all body fat).\n\nThe technology options for skin tightening and body contouring have included vacuum massage, infrared laser energy, high frequency focused ultrasound, cryolipolysis, radiofrequency energy and various hybrid energy device options. Radiofrequency energy devices have remained the most common and dominant technology in the noninvasive management of skin tightening, cellulite improvement and body contouring enhancement, as they can treat all these conditions with relatively consistent results.\n\nThe RF energy is high frequency alternating electrical current that passes into the dermis and hypodermal tissues without disruption of the epidermal-dermal barrier. The high frequency oscillating electrical current results in collisions between charged molecules and ions and the micromolecular mechanical energy from these collisions is transformed into heat. This biological RF heat occurs irrespective of chromophore or skin type and is not dependent upon selective photothermolysis. The RF heat has different biological and hence, clinical effects, depending upon the tissue targeted. In the dermis, where the primary cellular element is the fibroblast and the extracellular matrix (ECM) is comprised of collagen, elastin and ground substances, the RF mediated thermal stimulation of the ECM results in an immediate and temporary shrinkage of the collagen triple helix. Further, the RF thermal stimulation results in a microinflammatory stimulation of the fibroblast which in response produces new collagen (neocollagenesis) and new elastin neoelastogenesis), and ground substances. RF thermal stimulation of adipose tissue results in a thermal mediated stimulation and augmented activity of lipase mediated enzymatic degradation of adipocyte derived triglycerides into free fatty acids and glycerol. This amplification of the physiologic breakdown and egress of the triglycerides out of the adipocyte, while keeping the adipocyte cell membrane and cell function intact, results in RF induced shrinkage of the fat cells and body contouring.\n\nThe Venus Legacy LB2 Body Applicator Combines Multi-Polar RF current and Pulsed Electromagnetic Fields (PEMF) in synergy with suction/vacuum. PEMF has been shown to increase fibroblast derived collagen production through a non-thermal mechanism of membrane stimulation, and the stimulation of fibroblast mediated angiogenesis which facilitates and enhances wound healing in tissues. Theoretically then, the synergistic RF and PEMF would create RF thermal collagen stimulation and PEMF non-thermal stimulation of collagen, RF thermally mediated reduction in adipocyte size and PEMF micro-tissue healing effects to minimize edema, swelling and downtime that are associated with pure RF thermal therapies.\n\nThe objective of this clinical study is to evaluate the safety and performance of RF and PEMF using the Venus Legacy LB2 body applicator following liposuction to the back, flanks and/or thighs.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
