Abstract:
An embolic protection device for capturing embolic debris released into a body vessel of a patient, comprising:a shaft member having a distal end and a proximal end; and a filtering assembly rotatably mounted on the shaft member, the filtering assembly including an expandable strut assembly and a filter attached to the expandable strut assembly for capturing embolic debris, the expandable strut assembly having a first set of struts, each strut having a first end and a second end; a second set of struts, each strut having a first end and a second end; and a deployment member movable between a collapsed position and an expanded position; the first end of the first set of struts and the first end of the second set of struts each being attached to the deployment member at different locations along the deployment member and the first set and second set of struts being movable between a collapsed position and an expanded position, the first set of struts being located proximal to the deployment member and the second set of struts being located distal to the deployment member, the filter being movable with the struts to the expanded position so that at least a portion contacts the wall of the vessel to capture embolic debris released into the body lumen.
