Abstract
The present disclosure describes a gastric jejunal tube having a gastric lumen and a jejunal lumen that run the length of the tube. The cross-sectional sizes of the lumens change from above to below the most distal gastric port. A method of making the gastric jejunal tube is also described.
Claims10
A gastric jejunal tube, comprising:
- a uniform outside diameter along an entire length of the gastric jejunal tube;
- an interior gastric lumen open to one or more gastric ports defined in the gastric jejunal tube, and an interior jejunal lumen open to one or more jejunal ports defined in the gastric jejunal tube;
- a balloon lumen that is reduced in cross-sectional size from distal to the one or more gastric ports relative to the a cross-sectional size of the balloon lumen proximal to the one or more gastric ports;
- an interior wall separating the interior gastric lumen from the interior jejunal lumen;
- the interior wall shifting at a location distal to a most distal of the one or more gastric ports such that, at the shift location of the interior wall, the interior gastric lumen decreases in cross-sectional size and the interior jejunal lumen increases in cross-sectional size along a remaining length of the gastric jejunal tube to a distal end of the interior jejunal lumen;
- and
- the interior wall extending at its shifted location to the distal end of the interior jejunal lumen.
