Abstract

Gastric volume of a patient is reduced by deploying an endoscope into a stomach through the esophagus. A plurality of anterior anchors are affixed to the anterior wall of the stomach. The anterior anchors are distributed along an anterior line of the stomach wall beginning near the cardia region and extending toward the stomach exit. A plurality of posterior anchors are affixed to the posterior wall of the stomach. The posterior anchors are distributed along a posterior line of the stomach wall beginning near the cardia region and toward the stomach exit. The anchor line and the stomach wall are drawn towards the posterior line of the stomach wall to reduce gastric volume.

Claims

1. A method for reducing gastric volume, the method comprising:

deploying an endoscope into a stomach through the esophagus;

affixing a plurality of anterior anchors to the anterior wall of the stomach, wherein the anterior anchors are distributed along an anterior line of the stomach wall beginning proximate the cardia region and extending toward the stomach exit;

affixing a plurality of posterior anchors to the posterior wall of the stomach, wherein the posterior anchors are distributed along a posterior line of the stomach wall beginning proximate the cardia region and extending toward the stomach exit;

drawing the anterior line of the stomach wall towards the posterior line of the stomach wall, whereby gastric volume is reduced.

9. A method according to claim 1, further comprising providing an adhesive composition on the stomach wall.

10. A method according to claim 9, further comprising preparing the stomach wall before providing the adhesive composition.

2. A stomach wall anchoring device comprising:

a stem comprising an anchor end and opposing connector end;

one or more anchor members proximate the anchor end, wherein the one or more anchor members each comprise an insertion configuration and a deployed configuration, wherein in the insertion configuration the one or more anchor members are aligned with the stem, and further wherein in the deployed configuration the one or more anchor members are not aligned with the stem; and

a connector proximate the connector end.

3. A device according to claim 2, wherein the connector comprises an eyelet.

4. A device according to claim 2, wherein the connector comprises a hook.

5. A gastric reduction kit comprising:

a plurality of stomach wall anchor devices, wherein each of the anchor devices comprises an anchor end and a connector end;

one or more contraction devices adapted to engage the connector ends of the anchor devices, whereby the anterior and posterior stomach walls can be urged towards each other.

6. A kit according to claim 5, wherein the anchor devices comprises a stomach wall anchoring device comprising:

a stem comprising an anchor end and opposing connector end;

one or more anchor members proximate the anchor end, wherein the one or more anchor members each comprise an insertion configuration and a deployed configuration, wherein in the insertion configuration the one or more anchor members are aligned with the stem, and further wherein in the deployed configuration the one or more anchor members are not aligned with the stem; and

a connector proximate the connector end.

7. A kit according to any of claim 5, wherein the one or more contraction devices comprise suture material.

8. A kit according to any of claim 5, wherein the one or more contraction devices comprises a rotating barrel take-up.

11. A kit according to claim any of claim 5, further comprising an amount of a biocompatible adhesive composition.
