Heat Treatment Catheter
First Claim
1. A heat treatment catheter for use in heating a biological site in a patient'"'"'s body, the heat treatment catheter including:
- an elongate electrode-carrying element;
a plurality of heating electrodes arranged at spaced intervals at a distal region of the electrode-carrying element; and
the distal region of the electrode-carrying element being formed into a predetermined, non-rectilinear shape so that, in use, when any two of the electrodes are energised with heat energy, overlapping heat treated zones are created by the energised electrodes to form a heat treated region extending between the two energised electrodes.

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).

8. A system for heating a biological site in a patient'"'"'s body, the system including:
-
an electrode-carrying element having a plurality of electrodes arranged at spaced intervals at a distal region, the distal region of the electrode-carrying element being arranged in a predetermined non-rectilinear shape; and a source of electromagnetic energy connectable to the electrode-carrying element to energise at least two of the electrodes simultaneously, with the electromagnetic energy associated with one electrode being out of phase with the electromagnetic energy associated with any one other, simultaneously energised electrode. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method of heating a site in a patient'"'"'s body, the method including:
-
positioning a distal region of an electrode-carrying element relative to the site, the distal region of the electrode-carrying element having a plurality of electrodes arranged at spaced intervals and the distal region of the electrode-carrying element being non-rectilinear in shape; supplying energy to at least two of the electrodes simultaneously with the energy supplied to each of the electrodes being out of phase; and maintaining the energy supply to the energised electrodes until overlapping heat treated zones are formed by the electrodes to form a heat treated region extending between the two energised electrodes. - View Dependent Claims (16)
