Catheter device and method for selective occlusion of arteries of the descending aorta or iliac vasculature

A method of guiding a catheter device within a vasculature of a patient and occluding a target artery or vasculature, comprising:

• a) providing a catheter device for accessing the vasculature of a patient, the catheter device including an elongated hollow housing with a distal end configured to be inserted within a vasculature or aorta of a patient and a proximal end configured to remain outside the patient, and a guidewire comprised of a memory material configured to be inserted within a lumen in the elongated hollow housing in a non-activated flat state and once outside the lumen and distal end of the hollow housing activated into a second state in a shape of either a coil, spiral, corkscrew, circle or other geometric shapes to guide the elongated hollow housing within the vasculature of the patient to a target artery without migrating into non-target arteries, and a plurality of balloons with each balloon connected to a separate lumen within the elongated hollow housing with each lumen connected to an inflation source at the proximal end of said separate lumen, and an inflation port connected to the distal end of the elongated hollow housing and fluidly connected to each separate lumen connected to each balloon;
• b) advancing the catheter device, with the guidewire in the activated state and the balloons in a non-inflated state, through the vasculature of a patient such that a distal balloon is positioned at a target artery in the patient;
• and
• c) inflating the distal balloon at the location of the target artery so as to isolate or occlude blood flow at the target artery and withdrawing the guidewire from within the elongated hollow housing out of the patient.
