Claim 15:
16. An apparatus, comprising:
(i) a catheter;
(ii) a tip electrode extending distally from the catheter, the tip electrode defining a central longitudinal axis and further defining a plurality of fluid apertures, the tip electrode comprising a distal inner surface;
(iii) a conduit extending within the tip electrode, the conduit comprising a first distal end defining a first distal opening, the first distal opening being positioned along the central longitudinal axis; and
(iv) a printed circuit board (PCB) comprising a second distal end defining a second distal opening, the second distal opening being positioned along the central longitudinal axis, the second distal end being interposed between the first distal end of the conduit and the distal inner surface of the tip electrode, the first distal opening and the second distal opening being in fluid communication with each other, the conduit configured such that fluid passed distally through a lumen of the catheter flows in a longitudinal direction through a space between the PCB and the tip electrode, prior to exiting through the fluid apertures.
