Claim 0:
1. An apparatus, comprising:
(i) a catheter;
(ii) a tip electrode at a distal end of the catheter, the tip electrode having a plurality of fluid apertures therein, a majority of the fluid apertures being located in a circumferential face of the tip electrode;
(iii) a structure comprising a conduit extending within the tip electrode, the conduit comprising a first distal end defining a first distal opening; and
(iv) a printed circuit board (PCB) comprising a second distal end defining a second distal opening, the first distal end being positioned relative to the second distal end such that the first distal opening and the second distal opening are aligned with each other, said structure being configured such that fluid passed distally through a lumen of the catheter flows in a longitudinal direction through the first distal opening and the second distal opening into a space between the PCB and an inner surface of the tip electrode, prior to exiting through the fluid apertures,
the conduit being configured such that the fluid exits a distal opening of the conduit, and is then deflected into the space by a distal face of the tip electrode.
