摘要：
A device for treating a lesion in a body lumen to enlarge a passageway in the body lumen having at least one cutting member and a tracking member. The at least one cutting member has a cutting surface and a separate material associated therewith. The cutting member and tracking member are connected at a distal portion and insertable into the body lumen as a unit, the cutting member configured for movement in a direction transverse to a longitudinal axis of the tracking member to widen a gap between the cutting member and tracking member at least at a distal region and to apply the separate material to an interior of the lesion.
