Abstract
Disclosed herein is an ablation catheter that includes an irrigation conduit, a force sensor, an electrode tip assembly, a seal, and a temperature sensor. The irrigation conduit defines an irrigation lumen configured to carry irrigation fluid to a distal end of the ablation catheter. The force sensors include a deformable body coupled to the irrigation conduit adjacent a distal end thereof. The electrode tip assembly is coupled to the deformable body and extends distally therefrom, and defines an interior cavity in fluid communication with the irrigation lumen and an exterior cavity in which a distal portion of the deformable body is received. The seal is disposed between the electrode tip assembly and the deformable body, and inhibits fluid flow between the interior cavity and the exterior cavity. The temperature sensor is coupled to the electrode tip assembly and extends from the electrode tip assembly through the irrigation lumen.
