<p>The present invention relates to a hollow fiber oxygenerator, comprising a housing, comprising a core wall and an outer wall spaced from the core wall thus forming a chamber between the walls, at least one blood inlet to and at least one blood outlet from said chamber, first and second caps closing the chamber at a first and, respectively, a second end thereof, one of the caps having at least one gas inlet, the other having at least one gas outlet associated therewith, selectively permeable continuous hollow fiber filaments extending inside the chamber between the first cap and the second cap, wherein the ends of the fibers are sealed between the core wall and the outer wall at the ends of the chamber spaced from the caps, thus leaving a header space between the sealings and the caps, the ends of the fibers being open, wherein the circumferential angle difference for the fibers between the two sealings is between 0° and 180° and to a method for oxygenating blood, comprising passing a free oxygen containing gas through a plurality of hollow fiber filaments extending principally axially through an oxygenerator chamber and passing blood through the oxygenator chamber, wherein the blood flows primarily axially through the chamber along the plurality of fibers, characterized in that the fibers are arranged in such a way that they cause integrally a helical flow of the blood around the axis of the chamber.</p> |
