Abstract
A heat treatment catheter (10) for use in heating a biological site in a patient's body includes an elongate electrode-carrying element (12). A plurality of heating electrodes (16) are arranged at spaced intervals at a distal region (14) of the electrode-carrying element (12). The distal region (14) of the electrode-carrying element (12) is formed into a predetermined, non-rectilinear shape so that, in use, when any two of the electrodes (16) are energised with heat energy, overlapping heat treated zones (36, 38) are created by the energised electrodes (16) to form a heat treated region extending between the two energised electrodes (16).
