Abstract
A catheter including an elongate drive shaft having a proximal end and a distal end, an ablation burr disposed at the distal end expandable between a first position and a second position, wherein in the second position has a greater transverse dimension than in the first position. The catheter of the present invention can include a mechanism for positioning the burr eccentrically within a vessel lumen. In this context, expansion means that the burr can ablate a lumen having a larger diameter than the diameter of the lumen of the guide catheter to which the device is advanced.
