Definition : Catheters designed for introduction into the mouth or nose and through the trachea that are long enough to make possible the advance of their distal tips into the esophagus. These catheters typically consist of a plastic hollow tube with appropriate characteristics according to the procedure to be performed. Dedicated esophageal catheters intended to measure the pressure (i.e., manometric) and/or pH value inside the esophagus are available; catheters used for brachytherapy treatment of the esophageal wall and to dilate esophageal strictures are also available.
