Title:
ABLATION DEVICE FOR REDUCING DAMAGE TO VESSELS AND/OR IN-VIVO STENTS
Document Type and Number:
WIPO Patent Application WO2000024321
Kind Code:
B1
Abstract:
An ablation burr has a body provided with an inner circumferential rim and an outer circumferential rim that are concentric and spaced longitudinally by a selected distance along the length of the burr. The outer circumferential rim has a generally smooth convex outer surface that reduces damage to a vessel wall or stent. A leading surface of the burr extends between the inner and outer circumferential rims in a substantially uniform, convave manner. An abrasive, for example, diamond grit, is provided on the leading surface. The burr is selectively rotated by a drive shaft, causing the abrasive leading surface of the burr to ablate unwanted deposits.
