| Zusammenfassung: | The present invention relates to medical devices in general, and in particular to catheter ablation systems for revascularizing occluded vein grafts.
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. |
