Abstract:
1. A method for flow reversal in an artery of the head or neck having a proximal segment that branches into first and second distal segments, the first distal segment having a lesion and a source of collateral flow, the method comprising the steps of: inserting the distal end of a catheter into the proximal segment, the catheter having a proximal end, a distal end, and an expandable device on a distal region of the catheter; locating the expandable device within the proximal segment; expanding the expandable device to at least partially obstruct the proximal segment, wherein the second distal segment is at least partially open and wherein flow in the first distal segment is reversed to pass over the lesion and into the second distal segment.
