ABSTRACT:
A system is provided that allows completely occluded blood vessels to be crossed. The system includes a pathfinding guidewire that is coupled to the distal end of an ultrasound catheter. The distal section of the pathfinding guidewire acts as a narrow extension of the distal end of the catheter which is effective in transmitting ultrasound energy to cross occlusions. Once the distal section of the guidewire has crossed the occlusion, the distal end of the catheter can be advanced over the distal section of the guidewire and against the occlusion to remove the occlusion.
