Claim Text:
1. An embolus deflector for protecting against cerebral embolization, the embolus deflector being deployable from a first ostium of the aortic arch selected from the group consisting of an ostium of a right common carotid artery, an ostium of a left common carotid artery, and an ostium of a brachiocephalic artery, the embolus deflector comprising a blood-flow-permeable covering configured to simultaneously extend over the first ostium and a second one of the group of ostiums, wherein the embolus deflector comprises: a hollow sheath; a generally elongated shaft, the shaft having a distal end and a proximal end and being arranged to pass through and be displaced linearly within the hollow sheath; an expandable shield extending from the shaft distal end, the expandable shield having an open configuration and a closed configuration, the expandable shield comprising a first petal and a second petal, the expandable shield comprising: wherein the expandable shield in the closed configuration is sized and configured to be advanced through the sheath, and the expandable shield is sized and configured to be converted from the closed configuration to the open configuration within the aortic arch, wherein in the closed configuration the first and second petals are held against each other in general longitudinal alignment with the shaft, and in the open configuration the first and second petals extend substantially radially away from each other and substantially radially away from the distal end of the shaft and define the oval periphery, wherein in the open configuration the expandable shield is sized and configured to be positioned within the aortic arch and against the aortic wall such that the expanded first petal extends over the first ostium while the expanded second petal simultaneously extends over the second ostium, wherein the expandable shield presents a low profile against the aortic wall and within a lumen of the aortic arch to thereby cause minimal resistance to blood flow in the aortic arch by permitting blood to flow through the aortic arch past the expandable shield and also to allow sheaths, catheters, or wires to pass through the aortic arch and past the expandable shield without passing therethrough.
