Abstract:
Rotational atherectomy devices and systems can remove or reduce stenotic lesions in blood vessels by rotating an abrasive element within the vessel. The abrasive element can be attached to a distal portion of an elongate flexible drive shaft that extends from a handle assembly. In particular embodiments, the handle assembly includes a compressed gas driven turbine member that drives rotation of the drive shaft. The turbine member can be rotatably attached to a carriage that is longitudinally translatable in relation to a housing of the handle assembly. The handle assembly can include a latch mechanism that when actuated allows the carriage to translate to a proximal-most position. While the carriage is in the proximal-most position, an open pathway is created so that a guidewire can be slidably passed through the handle assembly and a lumen of the drive shaft.

Claim (Index 1):
A method of performing a rotational atherectomy, the method comprising:\n advancing a drive shaft of a rotation atherectomy device along a guidewire so that a set of five eccentric abrasive elements mounted along a distal end portion of the drive shaft is directed toward a targeted vessel, the drive shaft comprising a torque-transmitting coil extending from a handle assembly and being configured to rotate in response to rotation of a rotatable member housed within the handle assembly, the set of five eccentric abrasive elements comprising a distal-most eccentric abrasive element, a proximal-most, and three intermediate eccentric abrasive elements, and both the proximal-most eccentric abrasive element and the distal-most eccentric abrasive element are smaller in maximum outer diameter than that of the three intermediate eccentric abrasive elements; and rotating the rotatable member coupled to a proximal portion of the drive shaft to drive rotation of the drive shaft about a longitudinal axis of the drive shaft.
