Abstract
A collapsible blood filtering aortic arch bridge comprising a dumbbell shaped chassis having a tubular waist, a first conical end, and a second conical end such that only a periphery of the first and second ends contact the intima of an aortic arch when the bridge is disposed and expanded within the aortic arch of a patient. The waist is flexible so that the bridge can bend to comply with the curvature of the aortic arch. The bridge additionally comprises a blood filtering sleeve disposed over an interior or an exterior of the chassis for filtering blood flowing through the bridge into aortic arch vessels of the patient when the bridge is disposed within the aortic arch. Furthermore, the bridge comprises a retrieval sleeve disposed over the exterior of the chassis for collapsing the bridge to a cylindrical form for retrieval of the bridge from the aortic arch.
