A multi-electrode lead ( 10 ) comprises an elongate carrier ( 12 ) having a longitudinal axis. A plurality of electrical conductors is carried by the carrier ( 12 ), a plurality of electrodes being connected in spaced relationship to each conductor. The electrodes ( 14 ) are arranged at axially spaced intervals along the carrier ( 12 ) so that, along the length of the carrier ( 12 ), any one electrode ( 14 ) associated with any one of the conductors only once has an electrode ( 14 ) associated with another one of the conductors adjacent to that any one electrode ( 14 ). In another aspect of the invention, an ablating device ( 50 ) comprises an elongate tubular sleeve ( 52 ) for effecting spot ablation of tissue, a sensing electrode catheter being receivable in the passage ( 54 ) of the sleeve ( 52 ) for assisting in positioning of the ablating electrode ( 56 ), in use Preferably, the sensing electrode catheter is the multi-electrode lead ( 10 ) of the first aspect of the invention.
