Abstract
An in vivo extrapulmonary blood gas exchange device is disclosed having a hollow fiber bundle in gaseous communication with a coaxial dual lumen tube and having a furling apparatus for twisting one coaxial lumen relative to the other. The furling apparatus enables the outside diameter of the bundle of gas permeable tubes to be selectively adjusted to provide either a furled, small insertion diameter when inserting the apparatus into the venae cavae of a patient or an unfurled, expanded oxygenation diameter after the apparatus is in place within the venae cavae and the bundle of gas permeable tubes is deployed therein. The oxygenator is inserted into the patient through a single incision at one of the right external iliac, common femoral, or internal jugular veins. A novel distal tip configuration permits the oxygenator to be inserted into the patient utilizing an over-the-guidewire intravascular insertion technique.
