Abstract:
1. A distal protection device comprising a catheter having a tube formed with cutouts therein to form a first set of elongated struts and a second set of elongated struts, the tube having a longitudinal axis and a transverse axis transverse to the longitudinal axis of the tube each of the elongated struts having a proximal end and a distal end, the elongated struts being movable between a retracted position and an expanded position wherein the distance between the proximal end and distal end in the retracted position is a first distance and the distance between the proximal end and distal end in the expanded position is a second distance less than the first distance, in the expanded position the elongated struts forming loops with an opening lying in a plane substantially parallel to the transverse axis of the tube, and filter material deployable by the loops of the struts, the first set of struts and the second set of struts being separately movable to the expanded position to enable actuation of the first set of struts to accommodate a first size vessel and actuation of the second set of struts to accommodate a second different size vessel.
