1. A lesion treating device for use with an intraluminal device having an expandable member, comprising:
- a longitudinal housing operable to be inserted into a lumen of an intraluminal device having an expandable member; and
a wire coupled to the longitudinal housing, the wire having an undeployed position and a deployed position wherein the wire extends outside of the longitudinal housing to be positioned between an inner wall of a body lumen and the expandable member of the intraluminal device;
wherein;
the longitudinal housing includes an opening in its sidewall; and
when the longitudinal housing is longitudinally moved with respect to the wire, a first end of the wire extends from and proximally past the opening into the deployed position.

Abstract
A lesion treating device for converting a standard balloon catheter into a cutting balloon catheter is provided. The device includes a longitudinal housing such as a tube which is sized to be inserted into a lumen of the balloon catheter and cutting wires disposed within the longitudinal housing in an undeployed position. When the longitudinal housing is moved relative to the cutting wires, the cutting wires extend out of the longitudinal housing. The balloon of the balloon catheter is then moved under the deployed cutting wires and inflated to convert the standard balloon catheter into the cutting balloon catheter.
