Abstract
A portable apparatus for collection and processing of human biological material, such as containing adipose extracted during a lipoplasty procedure, is useful for multi-step processing to prepare a concentrated product (e.g., stromal vascular fraction) or a fat graft composition. The apparatus has a container with a containment volume with a tissue retention volume and a filtrate volume separated by a filter and with a tapered portion to a collection volume for collecting concentrate product. The apparatus includes a mixing device disposed at least in part within the tissue retention volume, and wherein the mixing device has a rotatable shaft extending from outside of to inside of the internal containment volume and has at least one mixing member that is disposed in the tissue retention volume with at least a portion disposed in the tapered portion of the internal containment volume and that is connected with the shaft to move through the tissue retention volume when the shaft is rotated.
