Abstract
A duodenal insert (20) comprises an elongated open-ended tube (22) having a passageway that extends from a first end (24) to a second end (26) for transporting partially digested food materials from the stomach (6) for a predetermined distance below the stomach to interrupt or reduce the intermixing of digestive fluids with the partially digested food materials. The duodenal insert is anchored within a pylorus (10) by a pair of spaced apart first and second rings (32 and 34) in a seated and sandwiched arrangement with the pylorus. Bores (38) and splits (40) are optionally disposed through the open-ended tube to provide the digestive fluids controlled access to the interior of the duodenal insert.
