Abstract: In general, the invention features an intravascular device, a delivery system, and methods for filtering or deflecting emboli or other large objects from entering a protected secondary vessel or vessels The intravascular device of the invention may prevent passage of a particle in a blood vessel from passing through a filter supported by a frame, upper and lower stabilizers, and a wire. The wire may be used to stabilize the device upon its deployment and installation within a blood vessel. Further, in some embodiments, the invention features a delivery system and methods for introduction of the device into a blood vessel.

Abstract: An intra-vascular device (100) may include a skeleton (102) to hold a blood filter (104), an upper member (110) to fit into a branch artery of an aorta, and a pair of lower members (106, 108) whose distal ends are not connected to each other, such lower members to press against a wall of an ascending artery and to provide lift to the device so that a middle portion of the device is above a lateral plane of the device. The device may be positioned in a middle area of an aortic arch near but not covering an opening of the branch arteries of the aorta, and may filter or deflect emboli or other large objects from entering into the branch arteries.
