Abstract
A method and apparatus for the in vivo oxygenation of blood without using or disturbing the patient's lungs. The apparatus comprises a plurality of small diameter gas permeable tubes connected to headers at each end. The headers in turn are connected on one end to a source of oxygen rich gas and on the other end to an exhaust means. The apparatus is positioned within the circulatory system of a patient. Particularly, an incision is made in the patient's femoral or iliac vein and the apparatus is threaded through the venae cavae and eventually out an incision in the patient's jugular vein. Both headers are positioned so that a source of oxygen rich gas can be attached and the gas circulated through the device.
