ABSTRACT:
A in-line device for the aseptic collection and treatment of tissue aspirate comprising a cartridge housing a removable filter is described. The device provides filter means for removing desired cells from a crude tissue aspirate, a rake for scraping the cells from the surface of the filter and a pressure relief valve to divert the flow of aspirate when the filter capacity is exhausted. With the filter and rake removed the outer cartridge also serves as the barrel of a syringe for further transfer of harvested cells.
