Abstract: Medical devices and methods for using medical devices are disclosed. A rotational atherectomy device may include an elongate shaft having a proximal end region, a distal end region and a lumen extending therein. The medical device may also include a cutting member positioned adjacent the distal end region of the elongate shaft. The cutting member may be radially expandable. The medical device may also include a sizing member positioned adjacent the cutting member. The sizing member may be radially expandable, and the radial expansion of the cutting member may be limited by radial expansion of the sizing member.
