A non-invasive method and apparatus for at least partially occluding the descending aorta of a patient and for manipulating core and cerebral temperature includes positioning an elongated tubular member which may have a moveable surface through the esophagus 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 tubular member may include a heat exchange surface and a heat transfer mechanism for transferring heat to the heat transfer surface or for transferring heat from the heat transfer surface in order to modify the temperature of a portion of the patient. |

DETAILED DESCRIPTION The present invention provides a non-invasive method and apparatus for treating cardiac arrest patients, patients in various forms of shock, such as hemorrhagic, cardiogenic, neurogenic and septic, patients suffering hypothermia and hyperthermia, and patients with head injury.
The invention relates to a device for inserting into an externally accessible tube of the patient, such as the patient's esophagus, to alter arterial blood pressures, myocardial and cerebral perfusion pressures, blood flow, cardiac output, and body temperatures of the patient.
A non-invasive method of enhancing cerebral and myocardial perfusion in a patient, according to an aspect of the invention, includes positioning a device in a portion of the patient's esophagus juxtaposed with the patient's descending thoracic aorta.
The device is used to move, or displace, a wall of the portion of the esophagus posterior-laterally in the direction of the descending thoracic aorta in order to at least partially occlude the descending thoracic aorta.
This increases central and intracranial arterial pressure without increasing central and intracranial venous pressure.
A non-invasive method of manipulating core and cerebral temperature of a patient, according to another aspect of the invention, includes positioning in the patient's esophagus a device having a heat transfer surface.
The device is positioned in a manner that the heat transfer surface is juxtaposed with a thoracic vessel through which blood is flowing, such as the aortic arch, the carotid arteries, the descending aorta or the heart.
Heat is exchanged between the heat transfer surface and blood flowing through the vessel across the wall of the esophagus and the wall of the vessel.
A non-invasive device for at least partially occluding the descending thoracic aorta of a patient and for manipulating core and cerebral temperature of a patient, according to yet another aspect of the invention, includes a tubular elongated member configured to a patient's esophagus and having a selectively moveable portion
