Patent ID: 8486060

Claim:
A method for tissue ablation comprising: positioning a radiofrequency (RF) applicator comprising an electrode carrier with one or more bipolar electrodes thereon at a target tissue site within a body cavity for ablating the interior lining of the body cavity; passing a current at an initial current level through the one or more bipolar electrodes to the target tissue site to apply an initial power density to destroy tissue, wherein power is applied at said initial current level for an initial time period; employing a vacuum source in fluid communication with the RF applicator to remove fluid generated during ablation away from the target tissue site, wherein excess fluid not removed by the vacuum source builds up at the target tissue site; and after the initial time period, ramping up the power density by increasing the current passed through the one or more bipolar electrodes to the target tissue site for a second time period, wherein the excess fluid build-up is vaporized during said second time period.
