Claim 7:
8. A method, comprising:
(i) using a tip electrode at a distal end of a catheter, passing an ablating signal into tissue;
(ii) while passing the ablating signal into the tissue, causing fluid to flow in a longitudinal direction through a conduit of a structure of the catheter;
(iii) causing the fluid to exit a first distal opening of the conduit and a second distal opening defined by a printed circuit board (PCB) the first distal opening and the second distal opening being aligned with each other; and
(iv) further causing the fluid to be deflected on a distal face of the tip electrode into a space between the PCB and an inner surface of the tip electrode, and to subsequently exit the tip electrode through a plurality of fluid apertures in the tip electrode.
