Gastrointestinal feeding and aspirating device for use in treating patients
First Claim
1. A gastrointestinal feeding and aspirating device for surgical insertion into a patient'"'"'s body through the abdominal and gastric wall, comprising:
- an aspirating lumen having an external end portion to be disposed outside the body, said external portion having an opening for connection to a source of suction and having an internal end portion to be disposed in the proximal segment of the small bowel, said portion having at least one orifice for intake of matter to be discharged from the body;
a feeding lumen having an external end portion to be disposed outside the body, said portion having an opening adapted to receive food to be transported through the lumen and having an internal end portion to be disposed in the proximal segment of the small bowel, said internal portion having an orifice therein for the discharge of food; and
means for securing the device to the patient'"'"'s body through the abdominal and gastric wall such that the internal portion of each lumen is located in the proximal segment of the small bowel, said feeding orifice being maintained at a location which is substantially three inches downstream of the most distal aspirating orifice, the portion of each lumen between the securing means and that lumen'"'"'s external opening being continuous.

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.

12. A gastrointestinal feeding and aspirating device for surgical insertion into a patient'"'"'s body through the abdominal and gastric walls, comprising:
-
an aspirating lumen having an external end portion to be disposed outside the body, said external portion having an opening for connection to a source of suction and having an internal end portion to be disposed in the proximal segment of the small bowel, and a mid-portion adjacent to the internal end portion to be disposed in the stomach, said internal end portion and said mid-portion each having at least one orifice for intake of matter to be discharged from the body; a feeding lumen having an external end portion to be disposed outside the body, said portion having an opening adapted to receive food to be transported through the lumen and having an internal end portion to be disposed in the proximal segment of the small bowel, said internal portion having an orifice therein for the discharge of food; and means for securing the device to the patient'"'"'s body through the abdominal and gastric walls such that the internal end portions of the aspirating lumen and the feeding lumen are located in the proximal segment of the small bowel, and said mid-portion of the aspirating lumen is located in the stomach, said feeding orifice being maintained at a location which is substantially three inches downstream of the most distal aspirating orifices, the portion of each lumen between the securing means and the lumen'"'"'s external opening being continuous. - View Dependent Claims (13)
