Apparatus and method for processing biological material
View Patent ↗The application discloses an apparatus and method for processing biological material, including a suspension of cells.
1. A method for reconstituting, washing or treating a cell preparation, comprising:
a. placing a cell preparation within a first chamber;
b. flowing the cell preparation from the first chamber into a second chamber under a centrifugal force field, wherein one of the first and second chambers further comprises a port having a resealable valve and the other of the first and second chambers further comprises a port having a member adapted to open the valve when the chambers are connected, wherein when the centrifugal force field is applied to the first and second chambers as a unit the cell preparation is transferred from the first chamber to the second chamber;
c. disconnecting the second chamber from the first chamber and closing the valve; and
d. subsequently flowing the cell preparation from the second chamber to one of the first chamber and a third chamber, and flowing the cell preparation from the one of the first chamber and the third chamber to the second chamber.
2. The method of claim 1 wherein the second chamber contains a solution for treating the cell preparation.
3. The method of claim 1 wherein at least one of the chambers contains a buffer for treating the cell preparation.
4. The method of claim 1 further comprising flowing the cell preparation from one of the first or second chambers to a further fluid destination or source.
5. The method of claim 1 further comprising connecting the second chamber to the third chamber for further processing of the cell preparation.
6. The method of claim 1 further comprising the step of reconnecting the first and second chambers for further processing of the cell preparation.
7. The method of claim 1 wherein the resealable valve is biased toward a closed position and automatically closes when the first and second chambers are disconnected.
8. The method of claim 1 wherein the member adapted to automatically open the valve is a cannula that establishes fluid communication through the valve when the first and second chambers are connected.
9. A method for reconstituting, washing or treating a cell preparation, comprising:
a. placing a cell preparation within a first chamber;
b. flowing the cell preparation from the first chamber into a second chamber under a centrifugal force field wherein the second chamber further comprises a port having a resealable valve and the first chamber further comprises a port having a member adapted to open the valve when the chambers are connected, wherein when the centrifugal force field is applied to the first and second chambers as a unit the cell preparation is transferred from the first chamber to the second chamber;
c. disconnecting the second chamber from the first chamber and closing the valve;
d. flowing the cell preparation from the second chamber into a third chamber, wherein the third chamber further comprises a port having a member adapted to open the valve of the second chamber when the chambers are connected;
e. processing the cell preparation in the third chamber;
f. after such processing flowing the cell preparation from the third chamber into the second chamber; and
g. disconnecting the second chamber from the third chamber and closing the valve.
10. The method of claim 9 wherein at least one of the chambers contains a solution for treating the cell preparation.
11. The method of claim 9 wherein at least one of the chambers contains a buffer for treating the cell preparation.
12. The method of claim 9 wherein the cell preparation is flowed into said second chamber under a force applied to the first and/or the third chamber.
13. The method of claim 9 further comprising flowing the cell preparation into a further fluid destination or source.
14. The method of claim 9 further comprising the step of connecting the second chamber to a fourth chamber for further processing of the cell preparation.
15. The method of claim 9 wherein the resealable valve is biased toward a closed position and automatically closes when the first and second chambers and the first and third chambers are disconnected.
16. The method of claim 1 , wherein flowing the cell preparation from the first chamber into the closed second chamber includes flowing the cell preparation along a single linear flow axis that defines a common central axis of the first and second chambers.
17. The method of claim 9 , wherein flowing the cell preparation from the first chamber into the closed second chamber includes flowing the cell preparation along a single linear flow axis that defines a common central axis of the first and second chambers.
