ABSTRACT:
An enteral feeding tube adapted for transpyloric passage and duodenal intubation of a distal end of the feeding tube in a patient capable of peristaltic contractions of the stomach wall. A flexible bolus is located at the distal end of the feeding tube, which has a feeding bolus and connected thereto by a linking means. The flexible bolus is of such length, diameter and deformability to initiate peristaltic movement of the stomach wall. The linking means is of outer dimensions smaller than the outer dimensions of the flexible bolus and the feeding tube, and is of a length, diameter and deformability selected to initiate and maintain peristaltic contractions in the stomach walls around and behind the flexible bolus. The continued peristaltic contractions act upon the flexible bolus and linking means, thereby drawing the feeding bolus and distal end of the feeding tube through the pylorus to achieve duodenal intubation.
