A system for removing matter from a partially or totally occluded stent includes a cutter that is urged radially outward toward the inner surface of the stent. Preferably, the cutter has a hardness that is less than or equal to the hardness of the material used to make the stent. Aspiration may be provided to remove portions of the occluding material from the vessel.

An expandable atherectomy burr has numerous cutting elements that expand radially outward as the burr is rotated. The cutting elements can include arms or flaps that have an abrasive surface thereon and expand as the burr is rotated. In an alternative embodiment, the burr includes a stack of cutting disks, each of which includes cutting elements that expand as the burr is rotated in order to create variably sized lumens in a vessel.
