Abstract:
1. A method of preparing fat for transplantation, comprising the steps of: mating a distal end of a first syringe with a first end of an adapter assembly; engaging a filter assembly with a second end of the adapter assembly, the filter assembly including a filter attached thereto; after the engaging and mating steps, inserting the first syringe into a receiver in a centrifuge insert, a combination of substances releasably retained inside a chamber of the syringe, the combination of substances including oil, fat and a denser substance; after the engaging and mating steps, coupling the centrifuge insert to a rotatable centrifuge member of a centrifuge; after the coupling step, centrifuging the first syringe to stratify the combination of substances into strata of oil, fat and the denser substance; before the centrifuging step, introducing a marking substance into the first syringe; after the coupling step, filtering at least a portion of the denser fluid stratum from the first syringe through the filter, the filter preventing passage of at least a portion of the fat stratum from the first syringe; after the coupling step, extracting at least a portion the oil stratum from an opening in a plunger head in a proximal portion of the syringe; and after the centrifuging step, removing at least a portion of a less viable fat tissue from the fat stratum in the first syringe.
