Abstract
Abstract A method for subdiaphragm hemorrhage control in a patient or for non-invasively enhancing cerebral and myocardial perfusion in a patient includes positioning a moveable surface through the esophagus adjacent the patient's esophageal-gastric junction and displacing the moveable surface thereby applying a force posteriorly in the direction of the patient's descending aorta sufficient to partially or substantially completely occlude the descending aorta. The moveable surface may be positionable in a lower portion of the esophagus where the esophagus and the aorta pass through the diaphragm or may be positioned in a portion of the patient's stomach juxtaposed with the patient's descending aorta.
