Abstract
Abstract A trans-abdominal stomach catheter placement system involving an external nasogastric intubation device with a mobile distal end embracing magnetic determination of the device adjacent the abdominal wall and displacement of internal organs thereat to facilitate stomach perforation, of a catheter of the Foley type introduced by means of a needle and having additional external securement and traction means therefor.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
83 words
A method of stomach manipulation for perforation thereof to receive a catheter comprising the steps of: intubating the stomach with an elongate flexible tubular member having a magnetically attractable tip thereon, magnetically attracting said tube tip from externally of the body thereby translating the stomach wall adjacent the tube lip laterally toward the body exterior and thereby displacing yieldable body members normally disposed therebetween, and perforating the body abdominal wall and the stomach therebehind in the immediate area of the magnetically attracted tip.
Claim 2
Independent Claim
83 words
A method of stomach manipulation for perforation thereof to receive a catheter comprising the steps of: intubating the stomach with an elongate flexible tubular member having a magnetically attractable tip thereon, magnetically attracting said tube tip from externally of the body thereby translating the stomach wall adjacent the tube lip laterally toward the body exterior and thereby displacing yieldable body members normally disposed therebetween, and perforating the body abdominal wall and the stomach therebehind in the immediate area of the magnetically attracted tip.
Claim 3
Dependent Claim
23 words
The method of claim 1 further including the step of inserting and securing a stomach catheter through the opening formed by the perforation.
Claim 4
Dependent Claim
54 words
An intubation system for implanting a catheter in a stomach comprising an elongated flexible tube for esophageal insertion into the stomach, a magnetically attractable tip on said tube, and, a magnet for manual positioning exteriorly of the body for attracting the magnetically attractable tube tip theretoward with a portion of the stomach wall therebetween,
Claim 5
Dependent Claim
54 words
An intubation system for implanting a catheter in a stomach comprising an elongated flexible tube for esophageal insertion into the stomach, a magnetically attractable tip on said tube, and, a magnet for manual positioning exteriorly of the body for attracting the magnetically attractable tube tip theretoward with a portion of the stomach wall therebetween,
Claim 6
Dependent Claim
27 words
The intubation system of claim 3 wherein said magnet comprises an annular magnet defining a central opening thereby to locate the attracted tip substantially at said opening.
Claim 7
Dependent Claim
14 words
The intubation system of claim 4 wherein said annular magnet is of frustoconical configuration.
Claim 8
Independent Claim
91 words
A method of catheter emplacement comprising the steps of inserting a flexible tubular member having a magnetically attractable tip into the stomach, magnetically attracting the tip of such member from exteriorly of the body toward the abdominal wall thereby to translate the adjacent portion of the stomach theretoward, perforating the abdominal wall and the stomach at the attracted area thereof, inserting a catheter through the abdominal wall and into the stomach, and, securing the catheter in position by means of a frictional clip exteriorly of the body adjacent the abdominal wall.
Claim 9
Independent Claim
91 words
A method of catheter emplacement comprising the steps of inserting a flexible tubular member having a magnetically attractable tip into the stomach, magnetically attracting the tip of such member from exteriorly of the body toward the abdominal wall thereby to translate the adjacent portion of the stomach theretoward, perforating the abdominal wall and the stomach at the attracted area thereof, inserting a catheter through the abdominal wall and into the stomach, and, securing the catheter in position by means of a frictional clip exteriorly of the body adjacent the abdominal wall.
