A device (180) for preventing stroke due to embolic material in the bloodstream of a patient, the patient having an aorta (20) with an ascending portion (20a) and a descending portion (20c), and one or more arch vessels (22, 24, 26) communicating with the aorta (20) for directing blood flow to the brain of the patient. The device (180) includes a physical deflector element configured for at least partial placement in the aorta (20) of the patient and a mounting structure coupled to the physical deflector element. The mounting structure is configured to engage at least one of the aorta (20) or an arch vessel (22, 24, 26) communicating with the aorta (20). The physical deflector element is constructed and arranged to direct blood flow in the aorta (20) in a manner that directs embolic material in the blood flow past the one or more arch vessels (22, 24, 26) and into the descending portion (20c) of the aorta (20). |
