EMBOLIC PROTECTION SYSTEM

摘要

A collapsible blood filtering aortic arch bridge (18) including an expandable and collapsible chassis (46) structured to provide the bridge (18) with a dumbbell-like shape when expanded having a tubular waist (50), a first conical end (38), and a second conical end (42) formed such that only a periphery of the first and second ends (38, 42) contact the intima (34) of an aortic arch (26) when the bridge (18) is disposed within the aortic arch (26) of a patient. The bridge (18) additionally includes a blood filtering sleeve (172) disposed over an interior or an exterior of the chassis (46) that is structured and operable to filter blood flowing through the bridge into aortic arch vessels of the patient when the bridge (19) is disposed within the aortic arch (26). The bridge (18) further includes a retrieval mechanism (178) structured and operable to collapse the bridge (18) to a cylindrical form for retrieval of the bridge (18) from the aortic arch (26).
