1. An apparatus for removing stenotic material from within a stent located within a body vessel, said apparatus comprising:

  • a stenotic material removal mechanism for removing stenotic material from within the stent, the stenotic material removal mechanism carrying an electrical current; and

    sensor means associated with said stenotic material removal mechanism for sensing current flow between said stenotic material removal mechanism and the stent, whereby the sensed presence of current flow is an indication of an unsafe condition or an appropriate endpoint for removal of stenotic material from within the stent based on the sensed proximity or contact between said stenotic material removal mechanism and the stent for effective recanalization of the body vessel.
