摘要：
According to some embodiments an ablation device comprises an elongate body (e.g. a catheter) having a proximal end and a distal end a first electrode (e.g. a radiofrequency electrode) positioned at the distal end of the elongate body at least a second electrode (e.g. a radiofrequency electrode) positioned at a location proximal to the first electrode the first electrode and the second electrode being configured to contact tissue of a subject and deliver radiofrequency energy sufficient to at least partially ablate the tissue at least one electrically insulating gap positioned between the first electrode and the second electrode and a filtering element configured to present a low impedance at a frequency used for delivering ablation energy via the first and second electrodes.
