A multilayer hollow fiber body (30; 30A; 30B; 30C; 30D; 56) useful, for example, in a blood oxygenator. The multilayer hollow fiber body (30; 30A; 30B; 30C; 30D; 56) comprises a single hollow fiber mat (20) arranged in the form of a body (30; 30A; 30B; 30C; 30D; 56) comprising a plurality of hollow fiber plies (31; 33). The mat (20) comprises a plurality of generally parallel hollow fibers (22) disposed at regular intervals, and a plurality of connecting fibers (24) holding the hollow fibers (22). The mat (20) is repeatedly folded over on itself along fold lines (FL-1; FL-2; ..., FL-N), each of which is at an oblique angle ( sigma ) to the hollow fibers (22), to form a multilayer hollow fiber body (30; 30A; 30B; 30C; 30D; 56) in which the hollow fibers (22) of any ply (31) of the multilayer hollow fiber body (30; 30A; 30B; 30C; 30D; 56) are disposed so as to cross the hollow fibers (22) of an adjacent successive ply (33) of the multilayer hollow fiber body (30; 30A; 30B; 30C; 30D; 56). Also disclosed is a method of making the multilayer hollow fiber body (30; 30A; 30B; 30C; 30D; 56). |
