SYSTEMS AND APPARATUS FOR CREATING TRANSMURAL LESIONS

摘要

An ablation system includes an ablation source, an ablation probe having an ablation element coupled to a power terminal of the generator, and a ground probe coupled to a return terminal of the generator, the ground probe configured to be inserted within a body during use. One of the ablation prob e and the ground probe is configured for being intravascularly introduced to a n interior of an organ, and another of the ablation probe and the ground probe is configured for being extravascularly placed in contact with an exterior o f the organ.
