ABSTRACT:
An apparatus and method for the non-surgical direct intubation of the duodenum or small bowel. The apparatus consists of an introducer tube comprising a double-lumen tubular member having a proximal end and a distal end. One of the lumens is dimensioned to permit the passage of a duodenal catheter therethrough. The other lumen is in fluid communication with the interior of an inflatable, anatomically-conforming balloon affixed asymmetrically near the distal end of the introducer tube. The anatomically-conforming balloon is stomach shaped when inflated. The introducer tube is advanced through the esophagus until the balloon is within the confines of the stomach. The introducer tube is then rotated so that the balloon is oriented toward (inflates toward) the greater curvature of the stomach. As the balloon is inflated, it expands into and conforms with the interior shape of the stomach. Upon completion of the inflation, the distal end of the catheter lumen of the introducer tube is in juxtaposition with the pylorus. A duodenal catheter is inserted through the catheter lumen of the introducer tube into the duodenum. After placement of the duodenal catheter, the balloon on the introducer tube is deflated and the introducer tube removed, leaving the distal tip of the duodenal catheter within the duodenum.
