Abstract:
An atherectomy device is used for removing a restriction in a blood vessel. The atherectomy device includes a cutting portion having a lumen therein, the lumen being sized to track over a guidewire, wherein an outer surface of the cutting portion comprises a cutting surface. An elongate shaping member is cooperable with the cutting portion and is disposed generally longitudinally relative to the cutting portion. The shaping member has an insertion conformation and an expanded conformation. The expanded conformation is radially expanded relative to the insertion conformation. The shaping member is configured to deform the cutting portion from an insertion shape into a cutting shape as the shaping member moves from the insertion conformation to the expanded conformation. A drive shaft is coupled to a proximal end of the cutting portion and is configured to be rotationally driven.
