Abstract:
This document describes rotational atherectomy devices and systems for removing or reducing stenotic lesions in blood vessels by rotating an abrasive element within the vessel to partially or completely remove the stenotic lesion material.

Claim (Index 1):
A rotational atherectomy device for performing rotational atherectomy to remove stenotic lesion material from a blood vessel of a patient, the device comprising:\n an elongate flexible drive shaft defining a longitudinal axis; an array of at least three spherical abrasive elements positioned along the drive shaft, the spherical abrasive elements fixed to the drive shaft such that a center of mass of each abrasive element is offset from the longitudinal axis, each abrasive element being spaced apart from an adjacent abrasive element by an abrasive element spacing distance; a metallic concentric stability element having a cylindrical shape and a center of mass aligned with the longitudinal axis, the stability element fixed to the drive shaft and distally spaced apart from a distal-most abrasive element of the spherical abrasive elements by a distal separation distance, the distal separation distance being greater than the abrasive element spacing distance, wherein the drive shaft includes a distal extension portion extending distally beyond a distal end of the stability element for a distal extension distance; and a coating on an exterior of the metallic concentric stability element.
