<p>An in vivo extrapulmonary blood gas exchange device (10) having a bundle comprised of a plurality of elongated gas permeable tubes (12) being bound at each end and enclosed within a respective air tight proximal and distal chamber (28, 30). A dual lumen tube having an outer lumen and an inner lumen (26) is situated relative to the gas permeable tubes (12) such that the outer lumen (24) terminates within the proximal chamber (28) and such that the inner lumen (26) terminates within the distal chamber (30). A plurality of crimps along the length of the gas permeable tubes (12) maintain the tubes (12) in a spaced relation one from another such that blood surface contact with the gas permeable tubes is maximized, disturbed flow of blood over the tubes is achieved and laminar blood flow between and around the gas permeable tubes is inhibited.</p> |
