ABSTRACT:
A catheter for insertion into the small intestine via the nose, the esophagus, the stomach and the duodenum. The catheter has a pair of inflatable balloons, a first one at its downstream end, and another a short distance (10 inches or 25 cm.) upstream of the first one. The two balloons are inflated when the catheter approaches the duodenum to facilitate passage through a portion of the duodenum which is inaccessible to a doctor who has access to the jejunum during surgery. The catheter may be advanced through the small intestine by grasping one or the other of the inflated balloons through the wall of the small intestine. When one of the balloons is in the inaccessible portion of the duodenum, the other is accessible, and vice versa.
