Patent ID: 7279107

Claim:
A system for processing blood components, the system comprising: a separation chamber comprising a chamber interior in which blood components are centrifugally separated, and an outlet port for passing at least some of the centrifugally separated blood components from the chamber interior; a flow path in flow communication with the outlet port of the separation chamber; a filter comprising a filter inlet in flow communication with the flow path, a porous filtration medium configured to filter at least some of at least one blood component from centrifugally separated blood components passed to the filter via the flow path, and a filter outlet for filtered blood components; a centrifuge rotor configured to be rotated about an axis of rotation, the rotor comprising a first portion configured to receive the separation chamber and a second portion configured to receive the filter, and wherein the system further comprises a pump configured to pump at least some of the centrifugally separated blood components from the chamber to the filter via the flow path; wherein the first and second portions are positioned with respect to one another so that when the separation chamber is received in the first portion and the filter is received in the second portion, the filter is closer than the interior of the separation chamber to the axis of rotation, and wherein the system is configured so that the rotor rotates during filtering of at least some of said at least one blood component via the filter.
