Non-invasive aortic impingement and core and cerebral temperature manipulation method
First Claim
1. A non-invasive method of at least partially occluding the descending thoracic aorta and manipulating core and cerebral temperature of a portion of a patient, including:
- positioning in the patient'"'"'s esophagus a device adapted to extend in said esophagus and selectively displacing with said device a wall of said esophagus posterior-laterally in the direction of said descending thoracic aorta; and
exchanging heat between said device and blood flowing through a thoracic vessel in order to increase or decrease the temperature of said blood flowing through said thoracic vessel.

Abstract
A method of non-invasively occluding the descending thoracic aorta to a desired extent in order to enhance cerebral and myocardial perfusion or the like, and/or of manipulating core and cerebral temperature of a patient, wherein a device is extended into the patient'"'"'s esophagus and manipulated to selectively displace a wall of the esophagus toward the descending thoracic aorta to thereby at least partially occlude the latter, and/or to exchange heat between a device positioned in the patient'"'"'s esophagus and a proximately located thoracic vessel in order to increase or decrease the temperature of blood flowing in such vessel.

7. A non-invasive method of enhancing cerebral and myocardial perfusion in a patient, including:
-
positioning a device having an elongated tubular member in a portion of the patient'"'"'s esophagus juxtaposed with the patient'"'"'s descending thoracic aorta; and displacing with said tubular member a wall of said portion of the esophagus posteriorly-laterally in the direction of said descending thoracic aorta in order to at least partially occlude said descending aorta and thereby increase central and intracranial arterial pressure without increasing central and intracranial venous pressure. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. A non-invasive method of treating shock in a patient, including:
-
positioning a device having an elongated tubular member in a portion of the patient'"'"'s esophagus juxtaposed with the patient'"'"'s descending thoracic aorta; and displacing with said tubular member a wall of said portion of the esophagus posteriorly-laterally in the direction of said descending thoracic aorta in order to at least partially occlude said descending thoracic aorta in order to increase central and intracranial arterial pressure and to reduce or stop blood flow in said descending thoracic aorta beyond the point of occlusion. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A non-invasive method of manipulating core and cerebral temperature of a patient, including:
-
positioning in the patient'"'"'s esophagus a device having a heat transfer surface in a manner that said heat transfer surface is at the juxtaposition with a vessel through which blood is flowing; and exchanging heat between said heat transfer surface and blood flowing through said vessel across said wall of said tube and a wall of said vessel. - View Dependent Claims (27, 28, 29, 30, 31, 32)
