SHAPED WIRE MULTI-BURR ROTATIONAL ABLATION DEVICE

摘要

The invention is a device for medical applications for differentially cutting abnormal deposits from within a patient's vessels. The device comprises one or more diamond plated burrs or cuffs (12) attached to a flexible drive shaft (16) which rotates at high speed. The drive shaft is placed over a preformed shaped guidewire (30) so that the drive shaft conforms to the shape of the guidewire, which has been preformed into a gentle "S" or "cork-screw" shape. The guidewire may be rotated at low speed.
