Claim:
1. A method of diverting emboli from cerebral circulation, comprising: placing a device at a neck of a patient, the device comprising members configured to compress carotid arteries of the patient, wherein each of the members comprises a foam or is nonporous, expandable, and capable of holding a fluid; positioning a first of the members at a first of the carotid arteries; positioning a second of the members at a second of the carotid arteries; compressing the first carotid artery by the first member and compressing the second carotid artery by the second member during a procedure on the patient, wherein the pressure applied by the first member and the second member exceeds a systemic pressure of the patient by at least 10 mm of Hg, wherein the procedure comprises a time period during which emboli released upstream from the first and second carotid arteries move towards the first and second carotid arteries and may move toward the patient's brain, and wherein the first member and the second member reduce blood flow in the carotid arteries, resulting in diversion of emboli away from the carotid arteries of the patient by flowing through a descending aorta of the patient instead of into the first and second carotid arteries; and releasing compression of the first and second carotid arteries.
