Claim 3:
4. A method, comprising:
providing a catheter comprising an elongated member having a member distal end and an axis of symmetry, the member distal end being configured to be inserted into an orifice of a body of a living subject;
locating a magnetic sensor in the member distal end;
fixedly attaching a cup-shaped electrode that caps a distal termination of the member distal end, the electrode being configured to convey radiofrequency (RF) energy to tissue of the body in contact with the electrode so as to ablate the tissue, wherein the cup-shaped electrode includes a base portion and a cylindrical wall portion surrounding the base portion;
extending a fiber optic (FO) along the axis of symmetry so that a FO distal end penetrates the electrode;
coupling a laser to a FO proximal end, the laser being configured to input optical energy to the tissue, via the fiber optic, so as to ablate the tissue; and
actuating the laser or supplying RF energy to the electrode.
