Abstract:
An embolic protection device for capturing embolic debris released into a body vessel of a patient, comprising:a shaft member having distal and proximal ends; and a filtering assembly rotatably mounted on the shaft member, the filtering assembly including an expandable strut assembly and a filter attached to the strut assembly for capturing embolic debris, the expandable strut assembly having a plurality of expandable struts adapted to move between a collapsed position and an expanded position, the filter element being movable with the struts to the expanded position to contact the wall of the vessel to capture embolic debris released into the body lumen, wherein the strut assembly is made from a segment of tubing having selectively removed portions and selectively remaining portions forming the struts of the strut assembly and further including a dampening element attached to the segment of tubing for at least partially absorbing vibratory motion which may be transmitted along the shaft member and to at least partially isolate such vibratory motion from the filtering assembly.
