  • Method of implanting an intravascular membrane lung
    Patent number: 5487727
    Abstract: An intravascular membrane lung is adapted for percutaneous venous insertion into a living body and comprises an elongated multi lumen catheter and elongated gas exchange members in the form of a large number of microporous fibers tethered at one end to the catheter and extending away from the catheter in all directions. The microporous fibers are in communication with the lumina of the catheter which includes one conduit for delivery of 100% oxygen to the fibers and another conduit for flushing away carbon dioxide from the fibers. The catheter extends between a proximal end and a distal end being a leading end for insertion into the body. The distal end includes a selectively inflatable balloon having an enlarged size larger than a nominal transverse dimension of said catheter and smaller than the inner nominal dimensions of any of the body cavities into which it extends.
    Type: Grant
    Filed: April 22, 1994
    Date of Patent: January 30, 1996
    Assignee: The Penn State Research Foundation
    Inventors: Michael T. Snider, Kane M. High, Georg Panol, James Ultman, Russell B. Richard, John K. Stene, Garfield B. Russell
