Claim Text:
1. A system for separating components of different densities from a physiological fluid containing cells using a centrifuge, the system comprising: a container, having a bottom, a top disposed opposite the bottom, and a sidewall extending between the bottom and the top, the container defining a cavity for receiving the fluid; a rigid insert slidably disposed in the cavity, the insert including a funnel-shaped concavity in an upper portion and a hole therethrough to form a funnel, the insert having a density such that upon centrifugation a selected component of the fluid resides within the upper portion of the insert; a container port disposed in the top of the container; and a cannula assembly receivable in the container port to butt against the insert and withdraw the selected component from the funnel-shaped upper portion, the cannula assembly further including an upper port displaced from a distal end of the cannula assembly to withdraw fluid at a predetermined height above the distal end of the cannula assembly, the distal end of the cannula assembly being a closed end to close the hole in the insert, the cannula assembly further including a lower port to withdraw the selected component.
