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 system for performing rotational atherectomy to remove stenotic lesion material from a blood vessel of a patient, the system comprising:\n an elongate tube defining a lumen; and a rotational atherectomy device comprising: an elongate flexible drive shaft comprising helically wound metallic filars that form a coil having an outer diameter, the drive shaft defining a longitudinal axis; an array of at least three eccentric spherical abrasive elements being fixed to the drive shaft such that a center of mass of each abrasive element is offset from the longitudinal axis; and a metallic stability element having a cylindrical shape defining an inner diameter, the metallic stability element being fixed to the helically wound metallic filars of the drive shaft, the metallic stability element having a center of mass aligned with the longitudinal axis; and a distal-most extension portion that extends distally of the metallic stability element to a distal free end; wherein the drive shaft, the abrasive elements, and the metallic stability element rotate together about the longitudinal axis.
