| 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 various fractions in the apparatus. A buoy system (300) that may include a first buoy portion and a second buoy member (304) operably interconnected may be used to form at least three fractions (330, 332, 334) from a sample during a substantially single centrifugation process. Therefore, the separation of various fractions may be substantially quick and efficient. Also selected fractions from the sample can be applied to a patient, either alone or as part of a mixture. |
