Abstract:
A biological fluid filter device comprising:a housing having an inlet and an outlet and defining a first fluid flow path and a second fluid flow path between the inlet and the outlet, wherein the housing essentially lacks a solid partition between the first fluid flow path and the second fluid flow path;a first porous element, comprising a leukocyte depletion medium, having a first surface and a second surface, interposed between the inlet and the outlet and across the first fluid flow path;a second porous element, comprising a leukocyte depletion medium, having a first surface and a second surface, interposed between the inlet and the outlet and across the second fluid flow path; anda space between the first porous element and the second porous element, the first surface of the first porous element opposing, and, for at least a portion of said surface spaced apart from, the first surface of the second porous element.
