摘要： An embodiment of an open-irrigated catheter system comprises a tip section, a distal insert, and mapping electrodes. The tip section has an exterior wall that defines an open interior region within the tip section. The exterior wall includes mapping electrode openings and irrigation ports. The exterior wall is conductive for delivering radio frequency (RF) energy for an RF ablation procedure. 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. The distal insert is positioned within the tip section to separate the open region into a distal fluid reservoir and a proximal fluid reservoir. The mapping electrodes are positioned in the mapping electrode openings in the tip section.

摘要： Disclosed herein, among other things, are methods and apparatus related to radio frequency (RF) ablation catheters. The present subject matter provides an ablation catheter system including a catheter body with a distal tip, and a thermocouple component at the distal tip. The thermocouple component is adapted to sense temperature of bodily fluid and/or tissue. The system includes a non-conductive insert configured to physically separate and thermally insulate the thermocouple component from the catheter body. Various embodiments include an open-irrigated ablation catheter system, the system further including at least one fluid chamber and a plurality of irrigation ports within the catheter body, where the plurality of irrigation ports enable fluid to exit from the at least one fluid chamber. The non-conductive insert is further configured to physically separate and thermally insulate the thermocouple component from the plurality of fluid flow channels and irrigation ports.
