A system and method of separation of therapeutic components from blood. The system includes a dual member centrifuge and a disposable single use fluid transfer set. The set includes an elongated flexible separation chamber having an input port, a separated component output port and a residual fluid output port. The input port and the separated component output ports are located at opposite ends of the elongated separation chamber. The centrifuge includes a receiving chamber with a selectively formed annular slot therein. The separation chamber is positioned in the annularly shaped slot and rotated at a predetermined rotational velocity. Fluids such as whole blood flows through the separation chamber and are separated into various therapeutic components such as platelet rich plasma and residual concentrated red blood cells. Platelet rich plasma can be drawn off as the separated therapeutic component. An alternate two part transfer set provides for highly efficient platelet pheresis.

An apparatus and method of separating a component from a collected quantity of fluid. The apparatus includes a dual member centrifuge and an associated fluid flow transfer set. The transfer set has a collection container in which a quantity of fluid can be initially accumulated. The collection container is formed as a disk-shaped plastic member with an elongated generally radially extending barrier member formed therein. A component collection container is in fluid flow communication with the disk-shaped container. The method provides for centrifugation of the collection container in the dual member centrifuge thereby separating out the selected fluid component. The component can then be pumped out of the collection container into the component accumulation container. The residual fluid can be sealed in the collection container for later use. The component collection container can be separated and sealed also for later use.

A method separates blood by centrifugation in a rotating chamber into a first separated blood component, a residual blood fluid, and an interface between the first separated blood component and the residual blood fluid. The method withdraws the first separated blood component out of the rotating chamber through a first outlet port, and also withdraws the residual blood fluid out of the rotating chamber through a second outlet port. During the separating step, the method accumulates a second separated blood component in the interface without withdrawal from the rotating chamber by monitoring the location of the interface within the rotating chamber and maintaining the interface at a location spaced away from flow communication with both the first and second outlet pods. After a selected time period, the method shifts the location of the interface within the rotating chamber into flow communication with a selected outlet port and withdraws the second separated blood component from the rotating chamber through the selected outlet port.

A fluid collection system includes an input unit having a hollow needle coupled through a section of flexible conduit to an anticoagulant reservoir which is in turn coupled via a second section of hollow conduit to a first sterile connector. A collection container, which can be a dry, flexible, plastic bag, is coupled by a plastic conduit to second and third sterile connectors. The first and second connectors can be joined together and sealed to form a sterile system. A transfer container includes a flexible plastic container coupled via a hollow plastic conduit to a fourth sterile connector. The fourth sterile connector is joinable with the third sterile connector to form a sterile two container system. Fluids collected in the primary container can then be transferred to the secondary container.
