Abstract

A fat harvesting system and related methods of harvesting and reinjecting fat that provides a medical professional with multiple technique options. Harvested fat can be subjected to a variety of pre-reinjection preparation steps within a single, self-contained reservoir such that the potential for contaminating the harvested fat is avoided. The fat harvesting system can be completely self-contained kit requiring no additional external systems or alternatively, can utilize available surgical suite systems, for example, vacuum to successfully harvest, prepare and reinject fat cells. The fat harvesting system can size harvested fat cells so as to be especially desirable for different injection locations in the body. The fat harvesting system is a single use, disposable system that requires no sterilization equipment and recovered and sized fat cells are maintained in a sanitary environment so as to avoid contamination that could result in having to discard recovered fat cells.
