Abstract
Cell expansion systems and methods of use are provided. The cell expansion systems generally include a hollow fiber cell growth chamber, and first and second circulation loops (intracapillary loops and extracapillary loops) associated with the interior of the hollow fibers and exterior of the hollow fibers, respectively. Detachable flow circuits and methods of expanding cells are also provided.
Claims9
A detachable flow circuit configured to attach to a fixed portion of a cell expansion system comprising a plurality of controllers, the detachable flow circuit comprising:
- a first fluid circulation path comprising a first fluid flow path having at least opposing ends, a first end of the first fluid flow path configured to fluidly associate with a first inlet port of a cell growth chamber and a second opposing end of the first fluid flow path configured to fluidly associate with a first outlet port of the cell growth chamber wherein a portion of the first fluid circulation path is configured to be disposably mounted to a first fluid controller of the fixed portion of the cell expansion system;
- a second fluid circulation path comprising a second fluid flow path having at least opposing ends, one end of the second fluid flow path configured to fluidly associate with a second inlet of the cell growth chamber and a second opposing end of the second fluid flow path configured to fluidly associate with a second outlet of the cell growth chamber, wherein a portion of the second fluid circulation path is configured to be disposably mounted to a second fluid controller of the fixed portion of the cell expansion system;
- a first fluid inlet path fluidly associated with the first fluid circulation path;
- a first fluid outlet path fluidly associated with at least one of the first or second fluid circulation paths;
- a first fluid connector path having at least opposing ends, a first opposing end of the first fluid connector path fluidly associated with the first fluid circulation path and a second opposing end of the first fluid connector path fluidly associated with the second fluid circulation path, wherein a portion of the first fluid connector path is configured to be disposably mounted to a third fluid controller of the fixed portion of the cell expansion system;
- and
- a second fluid connector path having opposing ends, one end of the second fluid connector path fluidly associated with the first fluid flow path and a second end of the second fluid connector path fluidly associated with the second fluid flow path, wherein a portion of the second fluid connector path is configured to be disposably mounted to a fourth fluid controller of the fixed portion of the cell expansion system.
