Abstract: In one aspect of the present disclosure, a commercial vehicle brake rotor is provided that includes a unitary, one-piece annular body having a central axis of rotation. The annular body includes vents and a braking portion having inboard and outboard braking surfaces. The annular body includes a central mounting flange having through openings to receive studs of a wheel hub.

Abstract: A cylindrical housing has a plurality of seriate slots. A helical cutter is rotatably mounted within the housing. A drive wire passes through the housing and connects with the cutter to provide rotational movement to the cutter. Plaque is caught between the slots and the blades of the rotating cutter, cut away from the arterial wall, ground up and flushed out through a catheter.
