Abstract

Patients having diminished circulation in the cerebral vasculature as a result of cardiac arrest or from other causes are treated by flowing an oxygenated medium through an arterial access site into the cerebral vasculature and collecting the medium through an access site in the venous site of the cerebral vasculature. In addition to oxygenation, the recirculating blood may also be cooled to hypothermically treat and preserve brain tissue. Isolation and cooling of cerebral vasculature in patients undergoing aortic and other procedures is achieved by internally occluding at least the right common carotid artery above the aortic arch. Blood or other oxygenated medium is perfused through the occluded common carotid artery(ies) and into the arterial cerebral vasculature. Usually, oxygen depleted blood or other medium leaving the cerebral vasculature is collected, oxygenated, and cooled in an extracorporeal circuit so that it may be returned to the patient.

Claims

1. A method for cerebral cooling, comprising the steps of:

inserting a first catheter into a right common carotid artery and expanding an occlusion member disposed about the first catheter;

inserting a second catheter into a left common carotid artery and expanding an occlusion member disposed about the second catheter;

inserting a third catheter into an inferior vena cava and expanding an occlusion member disposed about the third catheter;

flowing oxygenated medium from the first catheter into the right common carotid artery;

flowing oxygenated medium from the second catheter into the left common carotid artery;

and withdrawing medium from the inferior vena cava.

2. The method of claim 1, further comprising the step of stopping blood flow within the aorta.

3. The method of claim 1, further comprising the step of performing a diagnostic or interventional procedure on the aorta.

4. The method of claim 1, further comprising the step of performing an open surgical interventional procedure on the aorta.

5. The method of claim 1, further comprising the step of performing repair of an aortic aneurysm, repair of an aortic dissection, reconstruction of the aorta, or endarterectomy.

6. The method of claim 1, further comprising the step of inserting a fourth catheter into a descending aorta and expanding an occlusion member disposed about the fourth catheter.
