Brief Summary:
This study is being performed to reduce unwanted abdominal fat using two different applicators for the Zeltiq System.

Condition or disease Intervention/treatment Phase
Fat Reduction in the Abdomen Device: The Zeltiq System Not Applicable

Detailed Description:
The primary objective of the study is to evaluate the performance of the CoolFlex applicator compared to the performance of the eZ App 6.3 applicator in the treatment of abdominal fat in terms of its ability to achieve a discernable change to the contour of the treated area.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 20 participants
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Other
Official Title: Non-Invasive Reduction of Abdominal Fat Utilizing the CoolFlex and eZ App 6.3 Applicators
Study Start Date : July 2011
Actual Primary Completion Date : January 2012
Actual Study Completion Date : January 2012

Intervention Details:
    Device: The Zeltiq System
    Non-invasive cooling is applied to the treatment area with a defined cooling rate and duration.
    Other Names:
    • Cryolipolysis
    • Lipolysis

Primary Outcome Measures :
  1. Independent imaging review [ Time Frame: 16 weeks ]
    The primary effectiveness endpoint is the percent of reviews by the reviewers which either identify no clinically significant difference in fat reduction between the two sides of the abdomen, or identify greater fat reduction on the side of the abdomen treated with the CoolFlex applicator at 8 weeks post-treatment. It is expected that the percentage of reviews identifying no clinically significant difference between the two sides of the abdomen or identifying greater fat reduction on the side of the abdomen treated with the CoolFlex applicator at 8 weeks post-treatment will be at least 75%.

Secondary Outcome Measures :
  1. Overall reduction [ Time Frame: 16 weeks ]
    Overall reduction in the fat layer thickness on each side of the abdomen, as demonstrated by comparison of pre-treatment and 8- and 16-week post-treatment ultrasound measurements, for all evaluable subjects (i.e., adequate ultrasound imaging data sets).

  2. Subject satisfaction [ Time Frame: 16 weeks ]
    Subject satisfaction with the Zeltiq procedure as determined by the results of a subject satisfaction questionnaire at the 8- and 16-week follow-up visits.
