ABSTRACT:
An apparatus for treating an occlusive region of a blood vessel includes a catheter including a first lumen extending from an end port to a first side port, and a second lumen extending from a proximal end of the catheter to a second side port. A balloon is mounted on the catheter between the first and second side ports. During use, a guidewire is placed into an occlusive region, and the guidewire is backloaded through the first and second lumens. The catheter is advanced over the guidewire, and the balloon is expanded to isolate the occlusive region. The guidewire is removed, and an agitator is advanced through the second lumen. After the agitator is agitated to dislodge occlusive material from the occlusive region, the agitator is removed, and the loose occlusive material is aspirated via the second side port.
