Abstract

An apparatus (10) for intraoperative calibration of a fundus fold cuff comprises an inlet having lead (14) the end of which facing the patient being connectable to an inflatable balloon (13) and the other end of which facing away from the patient having means for inflation/deflation of the balloon 13 and for measurement of the internal pressure of the balloon (13). The balloon (13) has, at least in the inflated state, an outer contour defining a seating surface (16) and two raised humps (17) which are sidewardly bordered. Fundus portions are joined together to form a cuff surrounding the esophagus, and the properties of the cuff are determined by the forces exercised by the cuff on the balloon.
