Abstract: A rotational atherectomy device advanceable over a guidewire. The rotational atherectomy device includes a drive shaft rotatably extending through an outer tubular member to rotate a cutting member positioned at a distal end thereof. The rotational atherectomy device further includes an insert positioned within the cutting member for frictional contact with the guidewire.

Abstract: A rotational atherectomy device including a drive shaft rotatably extending through an outer tubular member to rotate a cutting member positioned at a distal end thereof. The rotational atherectomy device further includes an elongate penetrator extendable distal of the cutting member a predetermined maximum distance and configured to stabilize the cutting member as the cutting member engages an occlusion to control the trajectory and advancement of the cutting member through the occlusion.
