摘要： This invention is a method, a device for introduction of a catheter (6C), and/or delivering a fluid, such as oxygenated blood, to a patient's vascular system including a cannula (2C) having an expandable portion (4C). The expandable portion (4C) is movable from a collapsed position to an expanded position. The expandable portion (4C) is inserted into the patient in the collapsed position which facilitates introduction and advancement of the cannula (2C) through the patient's blood vessel. After introduction into the patient, the expandable portion (4C) is moved to the expanded position. The expandable portion (4C) protects the blood vessel against fluid forces when flowing a fluid through the cannula (2C), and protects the vessel from contact with the catheter (6C) advanced through the cannula (2C).

摘要： A multi-lumen catheter (10) having a reinforcing member (42) wrapped around at least one of the lumens (40) in a helical manner. An inflation lumen (43) is positioned outside the reinforcing member (42) for inflating a balloon (11) carried by the catheter (10). A two-lumen extrusion (339A) is bonded to the reinforced lumen (337A) to form the multi-lumen catheter. The multi-lumen catheter is particularly useful as an aortic occlusion catheter.
