摘要:
A device temporarily positionable within an aortic arch for deflecting embolic particles released during a therapeutic or diagnostic procedure comprises a resilient frame defining an opening and a barrier disposed in the opening. The barrier has a plurality of openings, which may be pores, proportioned to allow passage of blood therethrough but to prevent passage of embolic particles. The barrier has a concave shape having a convex surface positionable in contact with a wall of an aorta to cover at least a brachiocephalic ostium. The frame may include an upstream end including a pair of lobes and an apex between the lobes, and has a generally tapered downstream end.
