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