  • Esophageal displacement electrode
    Patent number: 5170803
    Abstract: An esophageal displacement electrode comprises a flexible tubular member designed to be inserted into the esophagus. 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 laterally in the esophagus and laterally displace the esophagus. 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 laterally, and engage and displace the esophagus with it.
