Abstract: An expandable endarterectomy cutting tool for use in incising plaque at a stenosis in an artery of a patient includes a guide wire,  an over-the-wire catheter, and a camming mechanism which is attached near the distal end of the guide wire.   The  cam mechanism  is  formed with  a plurality of ramps which incline outwardly from the guide wire  in a distal  direction  along  the  guide wire.   A plurality of tethers each have one end attached to the catheter and their other end slidably mounted on one of the ramps  in  the  camming  mechanism.    A  cutting  blade  is attached to each tether near the end of the tether in the ramp so that as the guide wire is pulled in a proximal direction relative to the catheter, the blades are pushed by the tether up their respective ramp to be radially extended from the cam mechanism.   On the other hand, pushing the guide wire in a distal direction relative to the catheter will draw each extended blade back down its respective ramp to retract the blades.  In operation, the cam mechanism of the tool is placed distal to the stenosis and the blades are extended.   The blades are then drawn across the plaque in the stenosis to weaken the plaque for subsequent  dilation  of  the  artery  in  an  angioplasty procedure.  The blades are then retracted and the tool is withdrawn from the artery.
