Abstract
An esophageal-stomach displacement electrode comprises a flexible tubular member designed to be inserted through the esophagus into the stomach. An electrode is carried by the tube in the region of its distal end. The tube is hinged near the distal end which enables that end of the tube to displace angularly in the stomach and displace the stomach wall. The stomach wall displacement may occur by angularly displacing the distal end or by otherwise pulling the tube partially out of the esophagus after its distal end partially displaced toward the stomach wall. A displacement mechanism is disposed in the tube in the region of the hinge and is controlled from a point externally of the body for causing the distal end of the tube to displace angularly, and to be positioned to engage and displace the stomach.
