Abstract
A deagglomerator for use in resizing masses of cells. The deagglomerator may include a plurality of apertures defined by a plurality of front and back edges. The masses of cells may be passed through the plurality of apertures from the front to the back, and from the back to the front, repeatedly. The deagglomerator may also include a plurality of blades that may aid in the deagglomeration of the cell masses. The deagglomerator may be configured between two syringes so that the tissue may be passed back and forth from the first syringe through the device to the second syringe, and then back again from the second syringe through the device and to the first syringe. In this way, the masses of cells may be properly deagglomerated.
Claims9
A device comprising:
- a housing assembly defining an inner volume including a cylindrical portion, the housing assembly comprising a first threaded port positioned along a central axis of the device at a first end of the housing assembly and defining a first fluid passage that opens to the inner volume, a second threaded port positioned along the central axis at a second end of the housing assembly and defining a second fluid passage that opens to the inner volume;
- a chopper positioned along the central axis within the cylindrical portion, the chopper comprising a first plurality of cutters extending radially relative to the central axis, wherein each cutter of the first plurality of cutters comprises two edges tapered in different directions, and wherein the first plurality of cutters defines a first plurality of apertures;
- a first slicer positioned along the central axis within the cylindrical portion, the first slicer abutting the chopper and comprising a second plurality of cutters arranged in a first grid, wherein each cutter of the second plurality of cutters comprises two edges tapered in different directions, wherein the second plurality of cutters defines a second plurality of apertures, wherein each aperture of the second plurality apertures is smaller than each aperture of the first plurality of apertures, and wherein each aperture of the second plurality of apertures has a length between 0.05 mm and 10 mm;
- and
- a second slicer abutting the first slicer, the second slicer comprising a third plurality of cutters arranged in a second grid that is oriented at an acute angle relative to the first grid.
