Patent ID: 7252675

Claim:
An embolic filtering device used to capture embolic debris in a body vessel, comprising: a guide wire having a proximal end and a distal end; an expandable filter assembly including a self-expanding frame having a first half frame adapted to move between an unexpanded position and an expanded position, the first half frame having a first control arm connected to a second control arm by a partial loop; a second half frame adapted to move between an unexpanded position and an expanded position, the second half frame having a first control arm connected to a second control arm by a partial loop, the partial loops of the first and second half frames cooperating to form a composite opening, the first control arm of the first half frame being disposed substantially adjacent to the second control arm of the first half frame and first control arm of the second half frame being disposed substantially adjacent to the second control arm of the second half frame; a filtering element attached to the partial loops of the first and second half frames; and means for rotatably mounting the expandable filter assembly to the guide wire.
