Method for placing a feeding tube inside a gastro-intestinal tract

摘要

An optical feeding tube includes an elongated sheath having a first lumen for delivering nutrients to a gastrointestinal tract and an imaging device disposed in a second lumen. The imaging device provides visualization of an area adjacent a distal end of the elongated sheath. The imaging device can be an optical fiber extending from a proximal end to a distal end of the elongated sheath. The optical feeding tube can also include a retention device. The method for placing the feeding tube involves passing the feeding tube through an opening in the abdominal wall and into a gastro-intestinal tract while observing a passageway ahead of the feeding tube.
