Islet cell transplantation machine for diabetes cure

摘要

An apparatus for collecting a subpopulation of cells larger than a predetermined size from a collagenase distended organ by circulating fluid through a closed loop system. The closed loop system includes a digesting chamber to liberate cells from the organ, a cell collection chamber, and a filter adjacent the cell collection chamber for retaining cells larger than the predetermined size. The circulating fluid transports liberated cells through the cell collection chamber to the filter. Subsequently, the cells on the filter are flushed back into the cell collection chamber by a density medium. A tube then withdraws the desired subpopulation of cells from the cell collection chamber.
