ENDOSCOPIC RESECTION METHOD

摘要

Embodiments of the invention are directed to a method of excising tissue including injecting fluid into the submucosa to raise targeted tissue. A first electrode is positioned below the targeted tissue within the injected fluid and a second electrode is positioned adjacent a surface of the raised targeted tissue opposite the first electrode. Electrical current is applied between the first and second electrodes and the targeted tissue is excised with the second electrode.
