Evaluate the safety and efficacy of the ZELTIQ CoolSculpting System using a small area applicator for non-invasive subcutaneous fat reduction in the distal thigh.

All subjects who met inclusion/exclusion criteria were enrolled in the study. Once enrolled, each of the 40 subjects was treated on one distal thigh.

Adverse event data were collected from the time of subject enrollment through the final follow-up visit, ap period of approximately 15 weeks.
