Method and apparatus for separating and concentrating a component from a multi-component material including macroparticles
First Claim
1. A system for separating and extracting selected fractions of a whole sample, the system comprising:
- a container;
a filtration system;
a separation system; and
an extraction system;
wherein the filtration system allows for separation of a macroparticle from a fluid of the whole sample.

Abstract
An apparatus that allows for separating and collecting a fraction of a sample. The apparatus, when used with a centrifuge, allows for the creation of at least three fractions in the apparatus. It also provides for a new method of extracting the buffy coat phase from a whole blood sample and mesenchymal stem cells from bone reaming material. A buoy system that may include a first buoy portion and a second buoy member operably interconnected may be used to form at least three fractions from a sample during a substantially single centrifugation process. Therefore, the separation of various fractions may be substantially quick and efficient.
