Abstract
An irrigation ablation probe comprises a generally rigid probe body and a handle mounted to the proximal end of the probe body. The generally rigid probe body comprises an ablation electrode at its distal end having at least one irrigation opening through which fluid can pass. An infusion tube extends through the probe body for introducing fluid into the ablation electrode. The irrigation ablation probe is useful for treating atrial fibrillation during open heart surgery.

An irrigation ablation probe comprising:
- an elongated probe body comprising an elongated ablation electrode having proximal and distal ends and defining an inner cavity, the elongated ablation electrode having at least one irrigation opening through which fluid can pass from the inner cavity to the outside of the elongated ablation electrode, the elongated ablation electrode being generally rigid from its proximal to its distal end so that the ablation electrode cannot bend during ablation, and wherein the elongated ablation electrode has an exposed distal portion that is generally straight and forms an angle a greater than 0° with the remainder of the elongated probe body, the angle a being preformed;
- and
- an infusion tube attached to the proximal end of the elongated ablation electrode for introducing fluid into the inner cavity.
