Abstract:
Rotational atherectomy devices and systems can remove or reduce stenotic lesions in implanted grafts by rotating one or more abrasive elements within the graft. The abrasive elements can be attached to a distal portion of an elongate flexible drive shaft that extends from a handle assembly that includes a driver for rotating the drive shaft. In particular implementations, individual abrasive elements are attached to the drive shaft at differing radial angles in comparison to each other (e.g., configured in a helical array). The centers of mass of the abrasive elements can define a path that fully or partially spirals around the drive shaft.

Claim (Index 18):
A method for performing rotational atherectomy to remove stenotic lesion material from an arteriovenous graft of a patient, the method comprising:\n delivering a portion of a rotational atherectomy system into the arteriovenous graft, wherein the rotational atherectomy system comprises:\n an rotational atherectomy device comprising:\n an elongate flexible drive shaft comprising a torque-transmitting coil and defining a longitudinal axis, the drive shaft being configured to rotate about the longitudinal axis; and \n a helical array of abrasive elements attached to a distal end portion of the drive shaft, each of the abrasive elements having a center of mass that is offset from the longitudinal axis, the centers of mass of each of the abrasive elements arranged along a spiral path around the longitudinal axis; and \n \n a controller; and \n rotating the drive shaft about the longitudinal axis such that the helical array of abrasive elements orbit around the longitudinal axis, wherein the controller determines the appropriate RPM for rotating the helical array of abrasive elements in the arteriovenous graft based on its diameter.
