Abstract: A centrifuge device is provided for the sizing and separation of constituents of a biologic mixture, e.g., adipose tissue. The device provides for the mechanical breaking down of the fibrous structure in the tissue by centrifugation causing the tissue to pass through a mesh element, or a sizing helix, or an extrusion element, whereupon the material is reduced to a slurry. This processed material may then be separated by centrifugation into its constituents, in order to harvest the fraction containing the multipotent cells. These multipotent cells may be utilized for various medical procedures to stimulate healing and tissue regeneration.

The insert has a density such that upon centrifugation a selected component of the fluid resides within the lumen. A container port is disposed in the top of the container to transfer the fluid into the container and to withdraw a fluid component other than the selected component from the container.

Abstract: A system operating as a centrifugal, liquid-liquid separator may be controlled, and even optimized, by automatic control of back pressure to establish an optimum position of the dispersion band therein. Optimizing to minimize impurities (from each other) in each of two separated phases is possible, even simultaneously, by reliance on a processor setting the settling lengths of both heavy and light phases at the same value. Settling length, defined in accordance with the invention, reflects a settling velocity multiplied by a residence time. Equating these lengths, for droplets of each in the other liquid, provides superior results over conventional settling theory maximizing settling area. Equalization of residence times did not provide an improvement over conventional settling theory.
