Abstract
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.
