Gastrojejunal tube apparatus and methods of use

A method of replacing a gastro-jejunal (GJ) feeding tube apparatus comprising:

• withdrawing a GJ feeding tube apparatus partially from a patient to expose a cut zone;
• cutting at least partially through the GJ feeding tube apparatus to establish an opening to a retrieval lumen extending to a distal end of the GJ feeding tube apparatus within the patient;
• advancing a guide wire through the retrieval lumen;
• withdrawing the GJ feeding tube apparatus from the patient while maintaining the guide wire within the patient;
• and
• advancing a replacement GJ feeding tube apparatus over the guide wire so as to position a gastric feed opening of the GJ feeding tube apparatus above the pylorus in the patient and a jejunal feed opening of the GJ tube apparatus below the pylorus.

A 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;
• and
• 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.
