1. A catheter adapted for deployment in a body vessel to occlude flow and remove material located distal to the site of occlusion, comprising:

  • an outer elongated hollow shaft configured for introduction into a blood vessel, an expandable occluder at or near the distal end of the outer shaft which substantially isolates a region within the vessel immediately external to the distal portion of the outer shaft from the region within the outer shaft and within the vessel distal to the occluder, an efflux port in communication with the lumen of the outer shaft that provides for the removal of material from the region within the vessel and distal to the outer shaft, an inner elongated and hollow shaft that is able to slide longitudinally within the outer shaft and is terminated distally with one or more openings that allow the contents of the inner shaft to exit its lumen and enter the vessel distal to the occluder in a pattern of flow determined in part by the arrangement of the one or more openings, an influx port in fluid communication with the lumen of the inner shaft, and a treatment port that provides access to the lumen of the outer shaft.
