CARDIO-EMBOLIC STROKE PREVENTION

摘要

An embolic protection device comprises an expandable, fenestrated, and substantially cylindrical frame, wherein the frame is configured to expand to engage an inner wall of a blood vessel, and wherein the frame defines a longitudinal passageway through the frame when expanded. The embolic protection device may also comprise a plurality of embolus flow modulating elements within the frame. The embolus flow modulating elements may be spaced apart and located at respective longitudinal or axial positions along the frame. The spacing apart of the flow modulating elements allows blood to pass between the flow modulating elements and through the frame in a direction generally transverse to the longitudinal passageway. The flow modulating elements are configured to deflect emboli and direct the emboli through the frame via the longitudinal passageway.
