Abstract
Gastrojejunal (GJ) tube apparatuses and methods for using the same where the GJ tube apparatuses having a plurality of tubes forming lumens within the apparatus and including a guidance tube having a closed end which is exposed by cutting off a portion of the GJ tube apparatus and which allows for insertion of a guide wire therethrough to assist in the placement of a new GJ tube such as when the existing tube becomes clogged or blocked.
Claims18
A gastrojejunal (GJ) tube apparatus, comprising:
- an apparatus body having an outer wall, a first proximal end, and a second distal end, where the outer wall includes an inflatable balloon portion;
- a first tube having an opening in the proximal end of the apparatus body and an opening in the inflatable balloon portion of the outer wall;
- a second tube having an opening in the proximal end and an opening between the proximal end and the distal end;
- a third tube having an opening in the proximal end and an opening in the distal end;
- and
- a guidance tube having a closed proximal end disposed between the proximal end and the distal end of the apparatus body, and an opposite distal end, and wherein cutting the apparatus body creates an opening in the guidance tube.

A gastrojejunal (GJ) tube replacement kit, comprising:
- a GJ tube apparatus having:
- an apparatus body having an outer wall, a first proximal end, and a second distal end, and an inflatable balloon portion;
- a first tube forming an inflation fluid lumen extending between the proximal end of the apparatus body and the inflatable balloon portion;
- a second tube forming a gastric feed lumen originating in the proximal end of the apparatus body, and terminating at a gastric feed opening formed between the proximal end and the distal end of the apparatus body;
- a third tube forming a jejunal feed lumen originating in the proximal end of the apparatus body and terminating at a jejunal feed opening formed in the distal end of the apparatus body;
- and
- a guidance tube forming a retrieval lumen originating at a closed, blind end, and extending to a distal end disposed at a location that is distal to the gastric feed opening;
- and
- at least one securing clip.

A gastrojejunal (GJ) medical apparatus, comprising:
- an apparatus body having an outer wall, a first proximal end, and a second distal end;
- a first tube in the apparatus body forming a lumen with a first opening at the apparatus body proximal end and a second opening at the apparatus body distal end;
- a second tube in the apparatus body forming a lumen with an open first end at the apparatus body proximal end and a closed second end disposed between the apparatus body proximal end and the apparatus body distal end;
- a third tube in the apparatus body forming a lumen with a closed first end disposed between the apparatus body proximal end and the apparatus body distal end and an opposite second end at the apparatus body distal end;
- and
- an anti-cut structure positioned between the apparatus body proximal end and the apparatus body distal end to limit severing the apparatus body;
- wherein the closed second end of the second tube is an inflatable balloon portion, and further comprising a fourth tube in the apparatus body forming a lumen with an open first end at the apparatus body proximal end, and a plurality of feed openings disposed between the apparatus body proximal end and the closed first end of the third tube.
