A surgical apparatus for treating a vessel blockage in a vessel of a patient having an elongated member having an outer wall, a first hole at a distal portion and a second hole spaced proximally from the first hole positioned in a side wall. A first lumen is provided within the elongated member for blood flow through the second hole, through the lumen and exiting the first hole to maintain blood flow during treatment of the vessel blockage. A motor driven impeller is rotatable during blood flow through the first lumen to enhance blood flow as blood flows into the second hole positioned proximal of the vessel blockage and exits the first hole distal of the vessel blockage during injection of fluid through one or more openings to treat the vessel blockage.
