Fluoroscopy-independent, endovascular aortic occlusion system

A method for deploying and selectively inflating a thoracic aortic balloon at a desired location within a thoracic aorta of a patient, comprising:

• measuring a distance between at least two readily externally identifiable anatomical landmarks of the patient, said anatomical landmarks including at least a symphysis pubis of the patient and a sternal notch of the patient;
• comparing the distance between the at least two external anatomical landmarks of the patient to a prediction model and calculating a length to which a calibrated endovascular wire and a balloon shaft of the thoracic occlusion system are to be inserted in the patient, the prediction model having correlation data for distances between the at least two external anatomical landmarks of torso extent of a pool of humans to centerline distances from a femoral artery at a femoral head to a location within the thoracic aorta of humans, the data measured using CT imaging;
• and
• inserting the calibrated endovascular wire and the balloon shaft to the length calculated for the patient independent of fluoroscopy.
