ABSTRACT:
A tissue ablation device includes an array of elongate electrodes configured to be deployed in tissue, wherein the deployed electrode array defines a tissue ablation region, an inflatable balloon configured to be deployed in tissue, and a coupler securing the balloon relative to the one or more elongate electrodes, wherein the balloon, when inflated, is configured to apply a force to tissue located in the tissue ablation region. An ablation device includes a first array of electrodes, a second array of electrodes, a first inflatable balloon, and a coupler securing the first balloon relative to the first and second electrode arrays. A method of ablating tissue includes positioning an array of elongate electrodes and an inflatable balloon proximate tissue to be ablated, inflating the balloon to compress a tissue region located between the balloon and the electrode array, and energizing the electrode array to ablate the tissue region.
