The expandable portion is operable between a closed position, wherein the expandable portion has a first diameter, and an opened position, wherein the expandable portion has a second diameter that is larger than the first diameter. An incising element is provided on the outer surface of at least one of the struts. The incising element has a blade that extends outwardly in a radial direction from the outer surface of the strut for creating an incision in atherosclerotic material located within a blood vessel when the expandable portion is in the opened position.
