Abstract
An improved catheter device includes an elongate shaft having a distal portion adapted to be disposed with the abdominal aorta and a plurality of expandable members disposed thereon. One expandable member is dimensioned and configured so that it rests within the iliac bifurcation when expanded. At least two expandable members are spaced apart from the one expandable member and configured to selectively occlude blood flow to different abdominal/pelvic arteries when expanded. Preferably, the distal-most and the proximal-most expandable members are spaced apart at a distance more than 20 cm and less than 40 cm (and most preferably on the order of 30 cm). The expandable members are preferably realized by four inflatable balloons controlled by fluidic pressure supplied thereto via corresponding inflation lumens in the shaft. The catheter device can be fixated within the abdominal aorta and manipulated in order to quickly and efficiently identify and isolate a hemorrhage flowing from an abdominal artery. In another aspect, the catheter device can be used in treating an abdominal aortic aneurysm.
