Abstract
An intraluminal scoring system for expanding an opening within an intraluminal passage includes a balloon catheter which is positioned alongside plaque lining a wall of the intraluminal passage. A wire is positioned between the balloon and the plaque so that the inflation of the balloon restricts the wire between the balloon and the plaque. After the balloon is inflated, a mechanical vibration is induced in the proximal end of the wire by a lithotripter actuator. The vibration travels through the wire to the distal portion, causing the wire to impact the plaque lining the wall of the passage causing scoring, compression, or fragmentation of the plaque.
