Abstract
An intravascular catheter device includes an expandable portion secured to a flexible catheter tube. The expandable portion is slidable relative to a sheath to selectively expose a plurality of struts for outward bowing movement and compression within said sheath. An incising element associated with one of the struts is configured to incise atherosclerotic material when the intravascular catheter device is placed within a blood vessel, the struts are exposed for outward bowing movement, and the expandable portion is retracted along the blood vessel.
