Abstract
A gastrointestinal feeding and aspirating device and method for use in treating patients. The device comprises an aspirating lumen, a feeding lumen, and an inflation lumen. When properly disposed within the patient's body, orifices in the aspirating lumen are positioned within the stomach and the proximal segment of the small bowel. The orifice in the feeding lumen opens at a site which is also in the proximal segment of the small bowel, but is further downstream than the aspirating orifices. The inflation lumen communicates with a balloon which is inflated after the insertion of the device in order to help maintain the device in its proper position. In an alternate embodiment of the invention, a fourth lumen is added for the sole purpose of aspirating the stomach.
