Design Details

Primary Purpose: Basic Science
Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: For this study, there will be three treatment groups in total. Details of each treatment are depicted in the addendum below. Groups 1 (laser only- 6 visits) and 2 (laser plus radiofrequency- 4 visits) will each consist of one patient. Group 3 (multiple vs. single laser treatments - 5 visits) will consist of three patients.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Diode Laser Treatment Only<br>Group 1: Patient 1- Laser Only This patient will present 20+, 14, 7, and 1 days prior to his/her scheduled abdominoplasty. Between 20 and 30 days prior, the patient will receive the first laser treatment on the 20+ day site 1. 14 days prior, the patient will receive laser treatment on the 14 day site 2. 7 days prior, the patient will receive laser treatment on the 7 day site 3. 1 day prior to the scheduled abdominoplasty, the patient will receive laser treatment on the 24 hour site 4. | Device: Venus Bliss<br>* The Venus Bliss™ system is an aesthetic medical device designed to non-invasively reduce subcutaneous adipose tissue of the abdominal area and flanks. It is intended for use in individuals with a Body Mass Index (BMI) of 30 or less. The device consists of an external treatment component and an internal control component. The treatment console is a 1060nm diode laser applicator and a radio frequency applicator. In addition, a Bliss Belt is provided with the system to properly secure one or more applicators to the patient's body during treatment. Finally, the touchscreen monitor is used by the clinician to control the setting display on the main console. It also keeps the clinician informed of the device's status and operating parameters.<br>|
| Active Comparator: Diode Laser and RadioFrequency Treatment<br>This patient will present 14 days and 7 days prior to his/her scheduled abdominoplasty. 14 days prior, the patient will be treated at site 1 with the laser and radiofrequency and site 3 with the laser only. 7 days prior, the patient will be treated at site 2 with the laser and radiofrequency and site 4 with the laser only. | Device: Venus Bliss<br>* The Venus Bliss™ system is an aesthetic medical device designed to non-invasively reduce subcutaneous adipose tissue of the abdominal area and flanks.

| Active Comparator: Multiple Diode Treatments<br>These patients will present for three treatments, each four weeks apart, with the abdominoplasty scheduled four weeks following the last laser treatment. These patients will receive laser treatment every four weeks for twelve weeks on the sites labelled Multiple Tx below (sites 1 and 2) on Days -90, -60, and -30 prior to abdominoplasty. At the final treatment (Day -30), two additional diodes will be placed on the sites labelled Single Tx below (sites 3 and 4). 4 diodes total will be used at this visit. Four weeks following this last treatment, the scheduled abdominoplasty will be performed and the pannus containing the treated tissue will be excised. | Device: Venus Bliss<br>* The Venus Bliss™ system is an aesthetic medical device designed to non-invasively reduce subcutaneous adipose tissue of the abdominal area and flanks.
