Study discontinued due to lack of subject follow-up.

The purpose of this study is to compare fat graft retention over time from lipoaspirate processed using two FDA-cleared devices: the Revolve System (K120902) and the AuraGen 1-2-3 with AuraClens Lipoaspirate Wash System (BK190433).

This is a single-center, prospective, randomized study enrolling patients undergoing an aesthetic fat grafting procedure to the breast without a breast implant. A total of 20 patients will be enrolled in the study. Ten patients will receive lipoaspirate processed with the Revolve and ten patients will have lipoaspirate processed with the AuraGen 1-2-3 with AuraClens.

Patients will be followed on post-procedure months 3, 6, and 12. Fat graft retention will be evaluated by photographic assessment by blinded reviewers, and 3D imaging. Patient satisfaction will be measured using the Breast-Q - Augmentation survey.

• Patients must be non-smokers.
• Patients with available/adequate harvest sites for fat grafting.
• Anticipated harvested fat volume between 400 and 1400 cc
• Anticipated fat injection volume 150-350 cc per breast
