| 摘要 |
<p>The present invention relates to a medical device for substantially uniform ablation of animal or human surface tissue, the device comprising a generator for generating radio frequency energy, an applicator probe comprising a cluster of at least three electrodes, said cluster of at least three electrodes being arranged in a substantially planar manner on a substantially planer member of the applicator probe, and a polarity alternator operatively connected to the generator and the at least three electrodes, the polarity alternator being adapted to automatically change polarity of at least one of the electrodes during ablation so as to form lesions about at least two electrodes, the polarity alternator further being adapted to repeatedly cycling lesion formation over a length of the electrode cluster during ablation so as to create a substantial and uniform ablation about at least two electrodes.</p> |
