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, 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.
