Abstract
An improved catheter device for selectively isolating and occluding a portion of the descending aorta and/or the iliac vasculature of a patient, including a guiding or isolating component on a distal end of an elongate hollow catheter shaft which is advanceable though the vascular system of the patient. The catheter shaft has a proximal portion that extends out from the patient and a distal portion adapted to be disposed within the vasculature of the patient. The guiding or isolating component as well as a plurality of expandable members are disposed on the distal portion. A number of expandable members are positioned on the catheter with dimensions and configured so that when expanded it rests within a target artery or vasculature to occlude blood flow. Other expandable members may be spaced apart from the isolating or fixation member and configured to selectively isolate and occlude blood flow through different portions of target arteries and other vasculature.
