Magnetically guidable energy delivery apparatus and method of using same

An energy delivery apparatus for delivering electrical energy at a target location, the energy delivery apparatus being usable in combination with a magnetic field. The energy delivery apparatus includes an electrical conductor, the electrical conductor having a substantially elongated configuration; an electrode for delivering the electrical energy at the target location, the electrode being electrically coupled to the electrical conductor and located at a predetermined location therealong; and a guiding element mounted to the electrical conductor in a substantially spaced apart relationship relative to the electrode, the guiding element including a magnetically responsive material. The energy delivery apparatus is constructed such that a movement of the guiding element causes a corresponding movement of the electrode. The magnetic field is used to move the guiding element in order to position the electrode substantially adjacent to the target location.
