Claim:
1. A method of diverting emboli from cerebral circulation, comprising the steps of: positioning an insertion device within the circulatory system of the patient, wherein the insertion device defines a first occluding catheter channel that extends from an insertion device first proximal opening to an insertion device first distal opening, wherein the insertion device defines a second occluding catheter channel that extends from an insertion device second proximal opening to an insertion device second distal opening, wherein the insertion device defines a pressure measurement channel that extends from a pressure measurement proximal opening to a pressure measurement distal opening, wherein the pressure measurement channel is isolated from fluid communication with the first occluding catheter channel and the second occluding catheter channel: positioning a first occluding catheter within e the circulatory system of a patient, wherein the first occluding catheter has a first shaft and a first occluding balloon that is located on the exterior of the first shaft, wherein the first shaft has a first proximal end that is located outside of the circulatory system of the patient, wherein the first occluding balloon is located within the circulatory system of the patient; positioning a second occluding catheter within the circulatory system of the patient, wherein the second occluding catheter is moved independently from the first occluding catheter, wherein the second occluding catheter has a second shaft and a second occluding balloon that is located on the exterior of the second shaft, wherein the second shaft has a second proximal end that is located outside of the circulatory system of the patient, wherein the second occluding balloon is located within the circulatory system of the patient; inflating the first occluding balloon of the first occluding catheter, wherein the first occluding balloon is arranged with respect to the first shaft such that an interior of the first occluding balloon is isolated from the circulatory system such that blood of the circulator/system is prevented from passing through the first occluding balloon and into the interior of the first occluding balloon; and inflating the second occluding balloon of the second occluding catheter, wherein the second occluding balloon is arranged with respect to the second shaft such that an interior of the second occluding balloon is isolated from the circulatory system such that blood of the circulatory system is prevented from passing through the second occluding balloon and into the interior of the second occluding balloon; wherein the first shaft has an exterior surface and an interior, wherein the exterior surface of the first shaft isolates the interior of the first shaft from the circulatory system from the first occluding balloon to the proximal end of the first shaft such that blood is prevented from passing through the exterior surface of the first shaft and into the interior of the first shaft from the first occluding balloon to the proximal end of the first shaft; wherein the second shaft has an exterior surface and an interior, wherein the exterior surface of the second shaft isolates the interior of the second shaft from the circulatory system from the second occluding balloon to the proximal end of the second shaft such that blood is prevented from passing through the exterior surface of the second shaft and into the interior of the second shaft from the second occluding balloon to the proximal end of the second shaft; wherein the inflated first occluding balloon and the inflated second occluding balloon occlude a right carotid artery and a left carotid artery of a patient; diverting the emboli from the right carotid artery and the left carotid artery by occlusion of the right carotid artery and the left carotid artery such that the diverted emboli flow through another artery of the patient instead of flowing through the right carotid artery and the left carotid artery measuring pressure of the circulatory system at a location distal from the first occluding balloon after inflation of the first occluding balloon; and measuring pressure of the circulatory system at a location distal from the second occluding balloon after inflation of the second occluding balloon, wherein the location distal from the second occluding balloon is a different location than the location distal from the first occluding balloon.
