Abstract
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 attached to a flexible drive shaft which rotates at a high speed. The drive shaft is placed over a preformed shaped guidewire 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.
