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 method for performing rotational atherectomy to remove stenotic lesion material from a blood vessel of a patient, the method comprising:\n delivering a rotational atherectomy device into the blood vessel, wherein the rotational atherectomy device comprises:\n an elongate flexible drive shaft defining a longitudinal axis, the drive shaft configured for rotation about the longitudinal axis; \n 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 spherical abrasive element is offset from the longitudinal axis, each spherical abrasive element being spaced apart from an adjacent spherical abrasive element; \n a metallic stability element that is fixed to the drive shaft and that has a center of mass aligned with the longitudinal axis, the metallic stability element distally spaced apart from a distal-most abrasive element of the spherical abrasive elements, wherein the drive shaft includes a distal extension portion extending distally beyond a distal end of the metallic stability element; \n a coating on an exterior of the metallic concentric stability element; and \n rotating the drive shaft about the longitudinal axis such that a portion of the drive shaft extending between the spherical abrasive elements traces a generally bicone shape.
