Abstract:
1. A method of preventing embolic material from entering a plurality of side branch vessels with a blood flow from an aortic arch of a patient, said method comprising: percutaneously introducing an embolic protection device comprising a protection unit into a first blood vessel while said protection unit is in a collapsed state, said protection unit comprising a selectively permeable unit that is permeable to blood; transvascularly delivering said embolic protection device into said aortic arch; and expanding said protection unit in said aortic arch to an expanded state such that said selectively permeable unit prevents embolic material from passing into said plurality of aortic side branch vessels while allowing blood to flow through said selectively permeable unit and into said plurality of aortic side branch vessels wherein: said embolic protection device comprises a connection point at which said embolic protection device is attached to a delivery unit, expanding said protection unit comprises asymmetrically expanding a first portion of said selectively permeable unit and a second portion of said selectively permeable unit from said connection point, said first portion is expanded in a first direction towards a descending aorta of said aortic arch, said second portion is expanded in a second direction towards an ascending aorta of said aortic arch; and wherein said first blood vessel is not one of said plurality of aortic side branch vessels that said selectively permeable unit prevents embolic material from passing into.
