Abstract
An intravascular catheter device for treating atherosclerotic material located within a blood vessel includes an expandable portion is secured to a catheter tube having a centerline. The expandable portion includes a plurality of struts pivotably attached to the expandable portion for movement between a closed position where the struts extend parallel to the centerline and an opened position where the struts splay outwardly at an angle from the centerline. A sharpened edge associated with at least one of struts creates an incision in the atherosclerotic material when the expandable portion is placed in the opened position and retracted axially through the blood vessel.
