Abstract From the Canadian patent

A filtration medium (14) is sealed within a housing (52 54). The filtration , medium (14) is sized and configured to define multiple filtration regions (28 30) within the housing (52, 54), through which independent though concurrent, blood filtration can occur. Each filtration region (28 30) is served by its , own inlet path, which conveys blood into the filtration region (28 30). The , filtration medium (14) in each region (28 30) passes the blood to remove at , least one undesired component such as leukocytes. After filtration, the multiple regions (28, 30) convey the blood into a single centrally located , manifold (36). A single outlet (18) communicates with the manifold (36).
