Patent ID: 7967817

Claim:
An ablating device, the ablating device comprising: an elongate, tubular sleeve defining an open passage; and an ablating electrode carried at a distal end of the sleeve for effecting spot ablation of tissue, a sensing electrode catheter being receivable in the open passage of the sleeve for assisting in positioning of the ablating electrode, in use; and a sensing electrode catheter received in the open passage of the sleeve, the sensing electrode catheter being in the form of a multi-electrode lead comprising: an elongate carrier having a longitudinal axis; and a plurality of electrical conductors carried by the carrier, a plurality of electrodes being connected in spaced relationship to each conductor, the plurality of electrodes being 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 the any one electrode.
