A system for ablating material in vein grafts includes an ablation burr that is rotated by a driveshaft. The ablation burr preferably includes one or more channels, blades or other mechanisms that direct ablated material and liquid proximally and/or outwardly against a vessel wall. Aspiration is used to remove ablated material and liquid from the treatment area. Finally, methods for treating vein grafts and original native arteries are disclosed.

An atherectomy burr includes a number of cutting blades having a less aggressive cutting action when rotated in a first direction and a more aggressive cutting action when rotated in a second direction. In accordance with one embodiment of the invention, each cutting blade includes an abrasive surface that is substantially parallel to the outer surface of the cutting burr. Each blade further includes a second cutting surface that is substantially perpendicular to the outer surface of the burr. By selectively rotating the burr in either direction, a physician can cause the less aggressive or more aggressive cutting surface to engage deposits in a patients vessel.
