Abstract
A method for tissue ablation is described. An RF applicator including an electrode carrier with one or more bipolar electrodes thereon is positioned at a target tissue site for tissue ablation. A current at an initial current level is passed through the one or more bipolar electrodes to the target tissue site to apply an initial power density to destroy tissue for an initial time period. A vacuum source in fluid communication with the RF applicator is employed to remove moisture generated during ablation away from the target tissue site. After the initial time period, the power density is ramped up by increasing the current passed through the one or more bipolar electrodes to the target tissue site for a second time period.
