Abstract
An esophageal/stomach placement electrode comprises a flexible tubular member designed to be inserted into the esophagus and/or stomach. An electrode is carried by the tube in the region of its distal end. The tube is hinged by its distal end which enables the end of the tube to laterally actuate in the esophagus or the stomach. An actuating mechanism is disposed in the tube in the region of the hinge and is controlled from a point external to the body for causing the distal end of the tube to actuate laterally, and engage the esophagus or stomach with it. The inner portion of the hinge is more bendable than the outer portion. Additionally, the control cables are all within the tubular member.
