A proximal balloon is located adjacent to the distal balloon. In a deflated configuration, the proximal balloon can pass through a diseased vessel. In an inflated configuration, the proximal balloon frictionally engages the diseased vessel while permitting at least some fluid flow through the diseased vessel and past the proximal balloon.
