Abstract

Devices and methods for tissue transfer are described where a cannula may be inserted into the breast of a subject at one of several points of entry. Insertion of the cannula into the breast may be accomplished by using a guidance system to distinguish between tissue types. Once desirably positioned, the cannula may be withdrawn from the breast while automatically (or manually) injecting the fat in multiple deposits of adipose tissue or fat such that the deposited fat remains within the tract formed by the withdrawn cannula. Multiple tracts of the deposited fat may be injected within the breast until the breast has been desirably remodeled and/or augmented.
