The present invention generally relates to a wire guide for use in procedures within a body vessel and to methods of using such devices. One embodiment of the wire guide includes a helically wound coil having its distal end closed with a cap and having a deflection wire housed within. The deflection wire simultaneously acts to deflect the distal end of the helically wound coil in a direction perpendicular to the longitudinal movement axis of the wire guide while moving a first blade attaching to a distal portion of the deflection wire from a retracted position to an extended position.
