Abstract
A device for introduction into a body vessel includes a shaft, a balloon positioned at the distal end of the shaft, a guidewire disposed longitudinally within the shaft to receive a guidewire during use, a balloon disposed at the distal end of the shaft, and longitudinal scoring wires to score a vascular lesion attached to the distal end of the shaft. The scoring wires are disposed over the balloon and disposed within the shaft. The proximal ends are welded or otherwise affixed to a spring mounted in the handle. The balloon expands when fluid is delivered to the balloon through the inflation lumen. This expansion pushes the scoring wires against the vascular lesion. The scoring wires attach to a source of vibrations. The scoring wires are made of a helical coil.
