An ablation catheter is provided which comprises a steerable catheter including a distal portion and a proximal portion. An ablation electrode is carried by the distal portion, with the ablation electrode having structure defining an interior space and having at least one aperture. A positional sensor is located in the interior space, wherein the proximal portion is connected to a source of cooling liquid which flows out of the aperture. The ablation catheter provides a suitable flow of fluid through the aperture while providing a space or volume sufficiently large for placement of a positional sensor. <IMAGE> |
