1. A guidewire comprising:
a wire characterized by a proximal segment and a distal segment characterized by a longitudinal axis;
a flow-directed structure disposed on the distal segment, said flow-directed structure comprising:
a first cylinder having an open proximal end and a closed distal end and longitudinal axis, said first cylinder extending along the distal segment of the wire, or extending distally from the distal segment of the wire, with the longitudinal axis of the first cylinder parallel to the longitudinal axis of the wire; and
