Guided ablation systems are provided, and methods of guiding electrodes into a target tissue for the ablation are also provided. The ablation systems can include a first guide needle and a second guide needle, and optionally a third guide needle, and the methods can include securing the tissue and guiding the ablation system into the tissue for the ablation, the securing and the guiding facilitated by the first guide needle and the second guide needle. The ablation systems include two electrodes, one of which is an outer coil electrode that is guided by the at least two guide needles. Dual coil ablation systems are provided and can also include a phase-offset between the coils to achieve a significant and surprising enhancement to the energy density provided by the systems, as well as an surprising enhancement to the uniformity of ablation provided by the systems and methods. |
