Patent ID: 6872307

Claim:
A blood processing system comprising a storage container, a centrifugal separation device that, in use, creates a centrifugal field that separates from blood a suspension of platelets having a first leukocyte concentration that is higher than a desired leukocyte concentration, the centrifugal field creating pressure, a finishing device communicating with the centrifugal separation device outside the centrifugal field that, upon contact with the suspension of platelets having the first leukocyte concentration, reduces the leukocyte concentration to the desired leukocyte concentration, thereby creating a finished platelet suspension, and a pump between the centrifugal separation device and the finishing device that, in use, pumps the suspension of platelets having the first leukocyte concentration from the centrifugal separation device directly through the finishing device under pressure from the centrifugal field and that conveys the finished platelet suspension from the finishing device directly into the storage container.
