A system for recanalizing an occluded blood vessel including a centering catheter employed to center an ablative guide wire within the blood vessel as the guide wire traverses the occlusion. The centering catheter includes a catheter body with an operative lumen through which the ablative guide wire is slidingly disposed. The centering catheter further includes a distally disposed centering mechanism that, when activated, centers the ablative guide wire within the blood vessel as it traverses the occlusion. The centering mechanism can comprise various embodiments including a single inflatable balloon or segmented inflatable balloon, which is in fluid communication with an inflation lumen. An airless preparation lumen may be disposed within the inflation lumen for ease of centering catheter preparation. The ablative guide wire includes insulation that is preferably formed of heat shrink tubing, which is stretched prior or concurrently with the heating process. The ablative guide wire includes a distal ablation tip having a non-traumatic structure and at least one discontinuous feature for creating high current densities for more efficient tissue ablation.
