An occlusion catheter for use during the therapeutic intervention of a cerebral blood vessel for flushing away fluid and debris from the area of the therapeutic intervention is provided. The catheter carries an inflatable occlusion balloon capable of being formed into a funnel with the larger end of the funnel facing distally. The funnel-shaped occlusion balloon seals the walls of the vessel to establish retrograde flow of blood. The peripheral walls of the funnel meet the vessel walls at an oblique angle and channel fluid and debris flowing proximally into the funnel to efflux ports at the base of the funnel.
