Abstract

Systems and methods for the washing and processing of biological fluid/biological cells are disclosed. The systems and methods utilize a disposable fluid circuit including a spinning membrane separation device to wash the biological cells.

First claim

The invention claimed is:

1. A system for the sterile, sequential washing of biological cells comprising:
(a) a first disposable fluid circuit for performing a first wash of biological cells comprising at least one separation device comprising a rotary spinner including a porous separation membrane, wherein said device is in fluid communication with a first product container and an access device for sterile connection to a source container of biological cells;
(b) a second disposable fluid circuit for performing a second wash of said biological cells comprising at least one separation device comprising a rotary spinner including a porous separation membrane, wherein said device is in fluid communication with a second product container and an access device for sterile connection to a source container of biological-cells obtained from processing through said first disposable circuit;
(c) a reusable cell processing apparatus comprising a drive unit for receiving said separation devices, said reusable cell processing apparatus configured for separately and sequentially receiving each of said separation devices of said first and second disposable fluid circuits, said reusable apparatus further comprising a programmable microprocessor configured to:
(1) effect washing of biological cells through said first and second disposable fluid circuits;
(2) prompt the operator to enter parameters for said first wash;
(3) prompt an operator to obtain a sample of said first wash;
(4) prompt an operator to remove said first disposable fluid circuit after the wash of said biological cells through said first disposable fluid circuit is complete;
(5) prompt the operator to load said second disposable fluid circuit;
(6) prompt the operator to enter parameters for said second wash;
(7) prompt the operator to obtain a sample of said second wash;
wherein at least one of said first and second disposable fluid circuits comprises a waste container in fluid communication with its respective separation device; and
wherein at least one of said first and second disposable fluid circuits comprises an in-process container in fluid communication with its respective separation device.

2. The system of claim 1 further comprising a third disposable fluid circuit comprising a separation device in fluid communication with a third product container and an access device for sterile connection to a source of biological cells.

3. The system of claim 2 further comprising a fourth disposable fluid circuit comprising a separation device in fluid communication with a fourth product container and an access device for sterile connection to a source of biological cells.

4. The system of claim 3 wherein at least one of said first, second, third and fourth disposable fluid circuits further comprises a waste container in fluid communication with its respective separation device.

5. The system of claim 4 wherein at least one of said first, second, third and fourth disposable fluid circuits further comprises an in-process container in fluid communication with its respective separation device.

6. The system of claim 4 wherein at least said first and second disposable fluid circuits comprises sample collection assembly.

7. The system of claim 6 wherein said sample collection assembly is adapted for receiving a sample of biological cells from a product container.

8. The system of claim 6 wherein said sample collection assembly is adapted for receiving a sample of biological cells from said source of biological cells.

9. The system of claim 6 wherein said sample collection assembly comprises a branched connector wherein one branch communicates with said product container or said source container and another branch communicates with a sample collection chamber of said sample collection assembly.

10. The system of claim 4 wherein at least said third disposable processing circuit further comprises a fluid path terminating in an access device adapted for sterile access to a container of treating agent.

11. The system of claim 4 wherein at least said third disposable fluid circuit further comprises a fluid path terminating in an access site for sterile access to a disposable fluid circuit comprising one or more treatment containers.

12. The system of claim 11 wherein said product container of said third disposable fluid circuit comprises an access site for sterile connection to said one or more treatment containers of said disposable fluid circuit.

13. The system of claim 11 further comprising a pooling container set.

14. The system of claim 11 wherein said one or more treatment containers comprises an access site for sterile connection to a container of said third disposable processing circuit.

15. The system of claim 1 wherein said reusable cell processing apparatus further comprises clamps and pumps that are actuated by said programmable microprocessor.

16. The system of claim 1 wherein at least one of said first and second fluid circuits includes an additional processing/separation chamber downstream of said rotary spinner.
