An endoscopic ablation system is provided for use with a flexible endoscope. The endoscopic ablation system includes a support member (26) for supporting at least two electrodes (28) that are connected to a RF generator. The electrodes (28) have a shape, size, and spacing that provide ablation betwee n the electrodes, while minimizing ablation of tissue directly underneath the electrodes. The system can also include a sheath that fits over a flexible endoscope, and a flexible coupling can join the support member to the sheath to facilitate intubation. The support member (26) can include a side opening , and the sheath can include a seal, so that the aspiration means of the endoscope may be used to evacuate the air from inside the body lumen and pul l the tissue to be treated into intimate contact with the electrodes. |
