Abstract
An endoscopically introducible expandable cautery device having a probe slidably received in a tube. The probe has a cauterizing end terminating in a balloon which is expandable upon inflation with fluid supplied through a first lumen in communication with a source of fluid such as a syringe. The surface of the balloon has at least one electrical contact that provides a cautery effect when in contact with tissue to be treated. The balloon is inflatable to a size larger than the bore of an endoscope though which it may be introduced.
