Abstract:
1. An open-irrigated catheter system for performing mapping and ablation functions, comprising: a tip section having an exterior wall that defines an open interior region within the tip section, wherein the exterior wall includes mapping electrode openings and irrigation ports, and wherein the exterior wall is conductive for delivering radio frequency (RF) energy for an RF ablation procedure, wherein the irrigation ports are in fluid communication with the open interior region to allow fluid to flow from the open interior region through the irrigation ports; a distal insert positioned within the tip section to separate the open region into a distal fluid reservoir and a proximal fluid reservoir; mapping electrodes positioned in the mapping electrode openings in the tip section; and noise artifact isolators fabricated from an electrical insulator, wherein the mapping electrodes are electrically insulated from the exterior wall of the tip section by the noise artifact isolators, wherein the noise artifact isolators have a lip extending out from the exterior wall of the tip section past the outside surface of the mapping electrodes.
