Multi-lumen enteral feeding and medicating device
First Claim
1. A multi-lumen enteral feeding and medicating device for supplying fluent materials to a patient having a stoma penetrating into the stomach, comprising:
- an elongated jejunal feeding tube adapted to pass through the stoma and having an inlet end adapted to be positioned externally of the patient and an elongated distal end adapted to extend beyond the stoma through the patient'"'"'s stomach and into the jejunum;
a gastric feeding tube coaxial with said jejunal tube and having a gastric lumen defined by the hollow interior of the gastric tube surrounding the jejunal tube with a distal end having an outlet within the patient'"'"'s stomach and an inlet end positioned externally of the patient;
said gastric tube having a balloon portion near its distal end operable to be extended to lodge against the stomach wall surrounding the stoma and a fluid lumen open at its distal end to the interior of said balloon and extending along the length of said gastric tube;
a support ring mounted on the external part of said gastric tube to engage the body of the patient surrounding the external opening of the stoma;
a feeding attachment at the inlet end of said gastric tube having a gastric inlet passage communicating through said gastric lumen with said gastric lumen outlet, a valve line passage communicating with said fluid lumen for applying positive and negative fluid pressure to said fluid lumen to thereby extend and retract said balloon, and a jejunal passage receiving said jejunal tube, the improvement whereinsaid jejunal tube is mounted for longitudinal sliding displacement within said jejunal passage and within the distal end of said gastric tube to enable relative longitudinal displacement between said jejunal tube and said gastric tube to permit adjustment of the extension of said jejunal tube beyond the distal end of said gastric tube, said jejunal tube being sealed within said jejunal passage so as to close the gastric lumen around the exterior surface of said jejunal tube to afford to introduction of a first fluent material through said gastric inlet passage and said gastric lumen into the interior of the patient'"'"'s stomach adjacent the distal end of the gastric tube;
said jejunal tube providing an uninterrupted lumen extending through said gastric tube and said stomach and having at its distal end outlet means for introducing a second fluent material into the jejunum.

Abstract
A multi-lumen enteral feeding and medicating device having a gastric tube adapted to be introduced into the interior of a patient'"'"'s stomach through a stoma. The gastric tube has a balloon to engage and seal against the interior wall of the stomach around the stoma and a locking ring to engage the skin of the patient surrounding the exterior opening of the stoma. A jejunal tube is slidably engaged in the gastric tube for relative longitudinal sliding displacement so that the distal end of the jejunal tube may be threaded through the stomach into the jejunum for introduction of a fluent material through ports adjacent the distal end of the jejunal lumen. A fluid lumen is provided in the gastric tube for applying positive and negative pressure to the interior of the balloon to extend and retract the same and an inlet attachment is provided for accessing the gastric lumen for introducing fluent material into the stomach through the gastric lumen. The jejunal tube passes through the gastric lumen and out through the inlet attachment. A sealing plug is provided to seal the inlet to the gastric lumen at the point where the jejunal tube exits the gastric lumen. The sealing plug operates to anchor the jejunal tube within the gastric lumen at the desired location which positions the distal end of the jejunal tube within the jejunum.

8. A method for the placement of a multi-lumen enteral feeding and medicating device for supplying fluent materials to a patient having a stoma penetrating into the stomach comprising the steps of
providing an enteral feeding and medicating device having a hollow gastric feeding tube with an internal gastric lumen and an elongated jejunal feeding tube slidably mounted within said gastric lumen, positioning said gastric feeding tube within the stoma with the distal end of said feeding tube positioned within the stomach; -
advancing the jejunal tube beyond the distal end of said gastric tube causing the distal end of the jejunal tube to pass through the stomach into the jejunum, and adjusting the extension of said jejunal tube to the patient'"'"'s anatomical requirements; and anchoring said jejunal tube within the gastric tube and sealing the entryway of said jejunal tube into the gastric lumen. - View Dependent Claims (9, 10, 11, 12)
