| 1. A device for passing fluid in a vessel while preventing emboli in the fluid from passing through the vessel, comprising:
a guide wire having a proximal end and a distal end;
a tubular shaft member having a proximal and distal end which is movable along the guide wire in a co-axial arrangement;
a filtering assembly including a plurality of splines formed from a portion of the tubular shaft member, the filtering assembly
being movable between a collapsed position and expanded position, each spline being movable into a recess formed on the filtering
assembly when the filtering assembly is in the collapsed position; and
a sheath, the filtering assembly being constricted within the sheath while in the collapsed position and expanded within the
vessel when released from constriction within the sheath to become disposed against the vessel to pass fluid in the vessel
while blocking the passage of emboli in the vessel.
