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 20):
The rotational atherectomy system of  claim 19 , wherein a proximal-most eccentric abrasive element and a distal-most eccentric abrasive element of said combination of multiple eccentric abrasive elements are both smaller in maximum outer diameter than at least one of the eccentric abrasive elements positioned between the proximal-most eccentric abrasive element and the distal-most eccentric abrasive element.
