ENDOSCOPIC ABLATION SYSTEM WITH SEALED SHEATH

摘要

An endoscopic ablation system is provided for use with a flexible endoscope for the ablative treatment of diseased tissue on the interior lining a body lumen. The endoscopic ablation system includes a support member for supporting at least two electrodes that can be electrically connected to a RF generator. The support member also includes a side opening, and can include a sheath having a seal, so that the aspiration means of an endoscope may be used to evacuate the air from inside the body lumen and pull the tissue to be treated into intimate contact with the electrodes on the support member.
