Abstract

An energy delivery apparatus (10) for delivering electrical energy at a target location, the energy delivery apparatus (10) being usable in combination with a magnetic field. The energy delivery apparatus (10) includes an electrical conductor (16), the electrical conductor (16) having a substantially elongated configuration; an electrode (22) for delivering the electrical energy at the target location, the electrode (22) being electrically coupled to the electrical conductor (16) and located at a predetermined location therealong; and a guiding element (26) mounted to the electrical conductor (16) in a substantially spaced apart relationship relative to the electrode (22), the guiding element (26) including a magnetically responsive material. The energy delivery apparatus (10) is constructed such that a movement of the guiding element (26) causes a corresponding movement of the electrode (22). The magnetic field is used to move the guiding element (26) in order to position the electrode (22) substantially adjacent to the target location.
