Abstract

A gastro-intestinal tube placement device for percutaneously placing gastro-intestinal tubes into the gastric cavity. The gastro-intestinal tube placement device of the present invention includes a containment element, such as an overtube, through which a gastro-intestinal tube can pass, and a displacing element assembly for pushing a gastro-intestinal tube through the containment element. The present invention also includes a gastro-intestinal tube having a collapsible internal bolster at its distal end, which bolster is capable of being manipulated to have a reduced lateral extent that allows the tube to be placed within the containment element.

Claims

1. A gastro-intestinal tube placement device comprising:

a containment element having proximal and distal ends and a central lumen extending therethrough;

a displacing element assembly disposed within the central lumen of the containment element, substantially from the proximal end to the distal end of the containment element; and

a spool disposed at the proximal end of the containment element, the spool including a tubular body with a proximal end and a distal end and including outwardly projecting ridges at the proximal end and the distal end of the tubular body, wherein the spool defines two aligned bore holes and wherein the containment element defines two aligned bore holes, the bore holes of the containment element aligned with the bore holes of the spool, and further comprising a plug disposed through the bore holes of the spool and the bore holes of the containment element.

2. A gastro-intestinal tube placement device comprising:

a containment element having proximal and distal ends and a central lumen extending therethrough;

a displacing element assembly disposed within the central lumen of the containment element, substantially from the proximal end to the distal end of the containment element; and

a gastro-intestinal tube having a proximal end and a distal end, and a collapsible internal bolster at the distal end of the tube wherein a first portion of the tube is disposed inside the central lumen of the containment element such that the internal bolster lies at the distal end of the containment element, wherein the containment element defines an opening along a length through which a second portion of the tube is disposed.

3. A gastro-intestinal tube placement device comprising:

a containment element having a proximal end and a distal end and a central lumen extending therethrough, wherein the proximal end defines two aligned bore holes;

a displacing element assembly disposed within the central lumen of the containment element, substantially from the proximal end to the distal end of the containment element;

a spool disposed at the proximal end of the containment element, the spool including a tubular body with a proximal end and a distal end and including outwardly projecting ridges at the proximal end and the distal end of the tubular body, wherein the spool defines two aligned bore holes, the bore holes of the containment element aligned with the bore holes of the spool; and

a plug disposed through the bore holes of the spool and the bore holes of the containment element.
