Abstract
A catheter has a two-piece tip electrode with a shell and a support structure defining a chamber, and a fluid distribution tube that extends longitudinally into the chamber, the fluid tube having fluid apertures along its length for distributing fluid more uniformly distributed throughout the chamber for improved cooling and thus minimizing the risk of char formation on regions of the tip electrode more prone to overheating.
