ABSTRACT:
An esophageal overtube for use with an endoscope in which the overtube has a conduit for evacuation of laser smoke and burnt tissue which is created during esophageal tumor ablation with laser therapy. A vacuum port on the esophageal overtube facilitates connection to a vacuum source which evacuates the laser smoke and burnt tissue to a site remote from the operating environment. An embodiment of the esophageal overtube has a bite block which can be either reusable or detachable from the overtube in a disposable version. Another embodiment of the esophageal overtube has a seal which seals the esophagus from the operating environment. Also disclosed are methods for using the various esophageal overtubes.
