EMBOLIC PROTECTION SYSTEM
First Claim
1. An embolic protection system, said system comprisinga collapsible blood filtering aortic arch bridge structured and operable to bend to comply with the curvature of an aortic arch of a patient into which the bridge is disposable, the bridge comprising:
- a chassis that is expandable and collapsible, the chassis structured to provide the bridge with a dumbbell-like shape when expanded having a tubular waist, a first conical end formed at a first end of the waist, and a second conical end formed at an opposing second end of the waist such that only a periphery of the first and second ends contact the intima of the aortic arch when the bridge is disposed and expanded within the aortic arch;
a blood filtering sleeve attached to the chassis, the blood filtering sleeve structured and operable to filter blood flowing through the bridge into aortic arch vessels of the patient when the bridge is disposed within the aortic arch; and
a retrieval sleeve disposed over an exterior of the chassis, the retrieval sleeve structured and operable to collapse the bridge to a cylindrical form for retrieval of the bridge from the aortic arch; and
a retrieval tool structured and operable to retrieve the bridge from disposition within the aortic arch, the retrieval tool comprising;
a multi-layer catheter;
a bridge coupling mechanism disposed at an end of the multi-layer catheter, the bridge coupling mechanism structured and operable to connect with the retrieval sleeve to retrieve the bridge from disposition within the aortic arch; and
a control handle connected to the catheter and structured and operable to control longitudinal movement of the retention wire and the outer sheath.

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.
