Abstract: An open-irrigated catheter system includes a catheter body and a tip assembly, coupled to a distal end of the catheter body. The tip assembly includes an exterior wall that is conductive for delivering radio frequency (RF) energy for an RF ablation procedure, and that defines an interior region. The exterior wall includes a number of proximal irrigation ports and a number of distal irrigation ports. At least one fluid chamber is defined within the interior region and is in fluid communication with at least one of the proximal irrigation ports and the distal irrigation ports. At least one fluid lumen extends from a fluid source, through the catheter body, to the tip assembly, and is in fluid communication with the at least one fluid chamber.
