Abstract

A method of deploying an intraluminal device to the cardiac region of the stomach and an intraluminal system used to deploy an intraluminal device to the cardiac region of the stomach, wherein the intraluminal device has a wall defining a surface and an open portion of the surface that is adapted to be aligned with the gastroesophageal (GE) junction. The surface and the cardiac portion of the stomach are conformable with each other. The method includes deploying the intraluminal device trans-orally to the stomach with an endoscopic deployment device and retaining the device against the cardiac region of the stomach with the open portion generally aligned with the GE junction. The intraluminal device is fastened to the stomach from the abdominal cavity with at least one laparoscopic instrument while concurrently visualizing the device with an endoscope in the stomach while it is being fastened. The laparoscopic instrument is adapted to respond to the endoscope in order to adjust location between the laparoscopic instrument and intraluminal device while the laparoscopic instrument is fastening the intraluminal device.

Claims (23)

1 . A method of deploying an intraluminal device to the cardiac region of the stomach, the device comprising a wall defining a surface and an open portion said wall that is alignable with the gastroesophageal (GE) junction, said surface and the cardiac portion of the stomach conformable with each other, said method comprising:

deploying the intraluminal device trans-orally to the stomach;

retaining the intraluminal device in the stomach in contact with the cardiac portion of the stomach with the open portion generally aligned with the GE junction;

fastening the retained intraluminal device to the cardiac portion of the stomach through a wall of the stomach from within the abdominal cavity with at least one laparoscopic instrument;

visualizing the intraluminal device within the stomach with an endoscope during the fastening, wherein said fastening comprises suturing with suture strands and reinforcing the suture strands at the abdominal side of each suture strand wherein said reinforcing comprises producing scar material in the stomach tissue contacted by the suture strand; and

explanting the intraluminal device by severing the suture strands in the stomach and pulling the knots of the severed suture strands through the stomach wall into the stomach.

2 . The method as claimed in claim 1 wherein said deploying comprises deploying the intraluminal device from a deployment device in the stomach and said retaining the intraluminal device comprises positioning the deployment device within the open portion of the wall in order to generally align the open portion with the GE junction.

3 . The method as claimed in claim 2 wherein said retaining the device further comprises applying a proximal force on at least one retention filament connected with the wall and the retention filament passing through the esophagus.

4 . The method as claim in claim 1 wherein said deployment device comprises said intraluminal device position at an exterior surface of the endoscope.

5 . The method as claimed in claim 1 wherein said reinforcing further comprises providing radial restraint to the suture strands.

6 . The method as claimed in claim 5 wherein said providing radial restraint comprises engaging adjacent suture strands with each other.

7 . The method as claimed in claim 1 wherein said producing scar material comprises positioning a biologically absorbable material between the suture strand and the stomach tissue.

8 . The method as claimed in claim 7 wherein said suture stands are made from a non-absorbable material.

9 . The method as claimed in claim 7 wherein said biologically absorbable material comprises multiple layers, each having a different rate of absorption.

10 . The method as claimed in claim 9 wherein the layer with a highest rate of absorption is positioned against the stomach wall.

11 . The method as claimed in claim 7 wherein said biologically absorbable material including a structural component that resists warping.

12 . The method as claimed in claim 9 wherein the one of said layers furthest from the stomach tissue having an outer surface that is adapted to resist adhering to another surface.

13 . The method as claimed in claim 1 wherein said intraluminal device has a plurality of structural members and has a higher density of said structural members proximal said opening than distal said opening.

14 . The method as claimed in claim 1 wherein said intraluminal device is made at least in part from a bio-absorbable material.

15 . The method as claimed in claim 1 wherein said wall includes an involute collar around said open portion.

16 . The method as claimed in claim 1 wherein fastening the intraluminal device to the cardiac portion of the stomach from within the abdominal cavity comprises looping a suture strand around a structural member of the intraluminal device.

17 . The method as claimed in claim 1 wherein said intraluminal device is used to treat at least one chosen from obesity, a metabolic disease, gastric reflux and hiatal hernia.

18 . The method as claimed in claim 1 wherein said explanting the intraluminal device further including withdrawing the intraluminal device through the esophagus.
