Abstract
A rotational medical device comprising an airfoil on a rotational drive shaft to generate lift forces generally directed radially away from a rotational axis of the drive shaft, thereby enabling the drive shaft and/or a working element thereon to achieve a working diameter during rotation that is greater than the resting diameter of the drive shaft and/or a working element thereon.
