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.

An apparatus is disclosed for inserting a medical device such as a catheter into a patient. The apparatus comprises a rigid obturator defining a distal obturator end.
