Study Details
Study Description
Brief Summary
The purpose of this study is to evaluate the effect on the subject outcome using the combination of the Zeltiq Cryolipolysis device and the Venus Concept multipolar radiofrequency device with varipulse technology for the enhanced non-surgical treatment of skin laxity in the flank area.

Detailed Description
Commercially available as the Zeltiq CoolSculpting system, cryolipolysis is FDA cleared for use in the United States for an indication of fat layer reduction in the flanks, thighs, and abdomen through cold-assisted lipolysis. CoolSculpting has been clinically proven to non-surgically reduce subcutaneous fat bulges, allowing patients to achieve noticeable and measurable aesthetic results without the pain, expense, downtime, and risks associated with existing invasive and minimally-invasive procedures. The Zeltiq CoolSculpting System is a non-invasive device designed to cool subcutaneous fat without affecting adjacent or underlying structures.
The RF device to be used in this study is a FDA cleared device used for aesthetic non-surgical skin tightening procedures including wrinkles, skin rhytides and cellulite in the face and body. The Venus Legacy utilizes a multi-polar radiofrequency system to deliver homogenous heating to multiple tissue depths. The Venus Legacy device also utilizes pulsed magnetic field technology as well as pulsed negative pressure technology.
The flanks of Ten (10) healthy adults (male and female), 21 to 50 years of age, who desire a reduction in focal fat of the flanks will be recruited from the investigator's subject populations. Informed Consent will be obtained from each subject during a screening visit.
The photos will be taken prior to the treatment series, one week post treatment series, at 3 and 6 months post treatment series for the evaluation of two blinded reviewers as well as for the investigator to assess.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Active Comparator: cryolipolysis Each patient is their own control and one side will have only a cryolipolysis treatment while the other side will have a cryolipolysis treatment plus multipolar radiofrequency and varipulse treatment. |
Device: cryolipolysis
Cryolipolysis technology uses the sensitivity of fat cells to cold injury, causing them to freeze and undergo cellular apoptosis.
Other Names:
|
Experimental: cryolipolysis, multipolar RF, varipulse Each patient is their own control and one side will have only a cryolipolysis treatment while the other side will have a cryolipolysis treatment plus multipolar radiofrequency and varipulse treatment. |
Device: multipolar RF, varipulse
Multi-polar Radio frequency (RF) technology combining pulsed electro magnetic fields (PEMF) and mild suction stimulation (varipulse).

Outcome Measures
Primary Outcome Measures
- General Improvement in Skin Laxity of the Flank Area [6 months]
Independent reviewer to identify the six month post-treatment photograph of the flank area treated with multi-polar radiofrequency, pulsed electro-magnetic fields and vacuum suction using the Global Aesthetic Improvement Scale (GAIS) where 3 = very much improved, 2 = much improved, 1 = improved, 0 = no change, -1 = worse, -2 = Much worse and -3 = very much worse.

Exclusion Criteria:
-
Subjects with active localized or systemic infections.
-
Immuno-compromised subjects.
-
Pregnant and/or lactating (All female volunteers will be advised about using birth control during the period of study).
-
In the opinion of the trained clinician, subject is unwilling or unable to adhere to all study requirements, including application and follow-up visits.
-
Subjects with a history of radiation therapy to the treatment area.
-
Subjects with any skin pathology or condition that could interfere with evaluation or with the use of typical ancillary medical treatments or care used before, during or after treatments.
-
Subject has had a surgical procedure(s) in the area of intended treatment.
-
Subject has had an invasive fat reduction procedure (e.g., liposuction, mesotherapy) in the area of intended treatment.
-
Subject has had a non-invasive fat reduction and/or body contouring procedure in the area of intended treatment within the past 12 months.
-
Subject needs to administer, or has a known history of subcutaneous injections into the area of intended treatment (e.g., heparin, insulin) within the past month.
-
Subject has a known history of cryoglobulinemia, cold urticaria, or paroxysmal cold hemoglobinuria.
-
Subject has a known history of Raynaud's disease, or any known condition with a response to cold exposure that limits blood flow to the skin.

-
Subject is taking or has taken diet pills or supplements within the past month.
-
Subject has any dermatological conditions, such as moderate to excessive skin laxity, or scars in the location of the treatment sites that may interfere with the treatment or evaluation (stretch marks is not an exclusion).

Participant Flow
Recruitment Details | Ten subjects between the ages of 21 and 50 years of age, requesting a reduction in focal fat of the flanks were recruited from a single outpatient clinic. |
---|---|
Pre-assignment Detail | Subjects received one session of cryolipolysis treatment on both sides of their body before one side of their body was treated with multipolar radiofrequency plus varipulse technology. Each subject acted as their own control. |
