8. A method of treating a lesion in a body lumen, the method comprising:
-
providing a cutting member; connecting a tracking member to the cutting member to form an assembly; inserting the connected cutting member and tracking member into the body lumen; inserting a catheter over the tracking member so the tracking member extends through a first lumen of the catheter and the cutting member does not extend through the first lumen; and moving the cutting member away from the tracking member into cutting contact with the lesion to enlarge a passageway in the body lumen; wherein the step of inserting the connected cutting member and tracking member comprises the step of inserting the cutting member and tracking member through a lumen of an angioplasty catheter, the angioplasty catheter being different than the catheter inserted over the tracking member.
