An expandable intraluminal catheter is used for removing occlusive material from a body passage. The catheter includes a handle having both a proximal handle end and a distal handle end. Attached to the distal handle end is an elongate tubular body, which includes a proximal body end and a distal body end. The elongate tubular body further includes a lumen between the proximal body end and the distal body end. A number of expandable segments are disposed on the elongate tubular body near the distal body end. These expandable segments can be mechanically activated by a user when the distal body end is within a blood vessel, to thereby isolate and partition occlusive material within the blood vessel. The isolated and partitioned occlusive material within the blood vessel can then be removed.
