Claim:
1. A method for forming an ablation treatment volume in tissue having a desired shape, comprising: positioning an ablation device having an elongate shaft and three elongate bodies extending from a distal end of the elongate shaft such that the three elongate bodies extend into tissue; delivering therapeutic energy to the tissue from only a first of the three elongate bodies to form an ablation treatment volume in the tissue; and simultaneously delivering a first fluid from the first elongate body and a second fluid from the other two elongate bodies to the tissue, the first and second fluids convecting the therapeutic energy in a desired direction such that the ablation treatment volume has a desired non-spherical shape; wherein each of the plurality of elongate bodies is offset from one another and spaced along an axis that defines a diameter of the elongate shaft with the first elongate body disposed between the other two elongate bodies.
