An assembly of non-powered sterile devices intended to be used to concentrate and collect nucleated cells, platelets, or bone marrow aspirate cells, from a volume of the patient's own blood/bone marrow, for human cell therapy. It typically includes flexible bags, tubing with slide clamps, and a filter to capture the target cells which are subsequently flushed using a harvest solution (not included) into a collection vessel. It is intended to be used at the point-of-care during a procedure, or in a laboratory. This is a single-use device.
