ABSTRACT:
An intraesophageal catheter comprising a tubular body, a pH sensor extending through the interior of the tubular body for pH measurement, and a balloon inflation pressure sensor communicating with the interior of the tubular body. The tubular body is comprised of clear polyvinyl chloride material and has a radiopaque stripe extending longitudinally along the tubular body. A plurality of circumferential gradations are marked on the tubular body. The pH sensor has a head portion fastened to the end of the tubular body and a conductor connected to and extending from the head portion to the other end of the tubular body. The head portion is comprised of a polycarbonate material having a smooth surface. The balloon inflation pressure sensor is a balloon that is positioned on the tubular body part from the head portion of the pH sensor. A balloon inflation channel extends through the interior of the tubular body and communicates with the balloon molded to the exterior surface of the tubular body.
