Patent ID: 8808217

Claim:
A system for collecting plasma reduced platelets from a donor, the system comprising: a) means for drawing whole blood from the donor therethrough; b) means for introducing anticoagulant into the whole drawn blood c) a separation chamber for separating the anticoagulated whole blood into a plurality of components, the components including a platelet component, d) a plasma container for storing an anticoagulated plasma component e) a platelet container for storing the platelet component; f) means for returning at least one of the plurality of components from the bowl back to the to the donor; g) a flow means for connecting the means for drawing whole blood, the separation chamber, the plasma container, the platelet container, and the means for returning at least one of the plurality of components; and h) a controller for controlling the flow means, means for returning, and the separation chamber so as to repeatedly draw whole blood from the donor into the separation chamber, extract platelets from the separation chamber into the platelet container, and return remaining components in the separation chamber back to the donor, wherein after a predetermined volume of platelets has been sequestered in the platelet container, platelets from the platelet container are reintroduced into the separation chamber so as to extract a plasma reduced platelet product from the separation chamber.
