Abstract:
1. A method of preparing fat for transplantation, comprising the steps of: drawing a mixture comprising dense matter, medium density live fat, and less dense oil into a first syringe having a needle coupled to a nipple of a chamber, a plunger head within the chamber, and a plunger rod connected to the plunger head; removing the needle; removing the plunger rod from the plunger head; inserting the first syringe into a centrifuge insert, the centrifuge insert including at least one cavity operable to receive the chamber, and a distal volume at a distal end from a proximal end of the at least one cavity thereof in fluid communication with the nipple; inserting the first syringe and the centrifuge insert into a centrifuge such that the nipple and distal volume are at a larger rotational radius within the centrifuge than the proximal end of the at least one cavity, and centrifuging the first syringe and centrifuge insert to stratify the mixture into strata of oil furthest from the nipple, live fat and the dense matter nearest the nipple; filtering at least a portion of the stratum of dense matter from the first syringe through the nipple and into the distal volume of the centrifuge insert; and extracting at least a portion the stratum of oil through the plunger head.
