1. A vessel occlusion system for occluding a thoracic artery of a patient between the left subclavian artery and an aortic bifurcation to reduce blood flow to the patients extremities, the system comprising:

  • a balloon shaft including a distal end portion and a proximal end portion, the proximal end portion including a port, the balloon shaft also including pre-calibrated length indicia on an external surface;

    an occlusion balloon connected to the distal end portion, the port being in fluid communication with the occlusion balloon;

    a balloon inflation lumen extending along a length of the balloon shaft, the balloon inflation lumen being in fluid communication with the balloon and the port;

    a curved tip at the distal end portion, the curved tip configured to limit perforation of vessels as the balloon shaft is advanced through blood vessels of the patient toward and through the target blood vessel; and

    a nomogram correlating a first distance between at least two externally identifiable boney anatomical landmarks of humans of a pool of humans and a second distance from an insertion puncture to the predetermined location of the humans, wherein a reference distance between the at least two externally identifiable external boney anatomical landmarks of the patients torso, the nomogram configured to enable a comparison of a measurement on the patient to the first distance on the nomogram to determine the correlated second distance such that the predetermined location is the determined second distance from the insertion puncture and the occlusion balloon is to be inserted into the patient and positioned at the predetermined location within the target blood vessel without using fluoroscopy, the pre-calibrated length indicia providing an indication of an insertion distance of the occlusion balloon from the insertion puncture, the nomogram also including a listing of a diameter of the aorta.
