Abstract

Methods and devices for providing a minimally-invasive placement of a mechanical structure for reducing the volume of a hollow body organ. Intragastric bands may be secured within the hollow body organ and then reduced in diameter to form a stricture within the hollow body organ. The strictures may be placed anywhere within the hollow body organ, and more than one stricture may be formed within the hollow body organ.

Claims

1. A method for reducing the volume of a stomach cavity, comprising:

positioning an intragastric band having an inner surface and an outer surface within the stomach cavity;

forming at least two pairs of folds of stomach tissue;

securing the intragastric band to the wall of the stomach cavity by securing the outer surface of the intragastric band between a first pair and between a second pair of folds of stomach tissue;

passing a first fastener through both the first pair of folds of tissue and passing a second fastener through both the second pair of folds of tissue; and

decreasing the diameter of the intragastric band to create a stricture within the stomach cavity to reduce the volume of the stomach cavity.

2. The method of claim 1, further comprising adjusting the diameter of the intragastric band having an adjustable mechanism for changing the diameter.

3. The method of claim 1, wherein securing the intragastric band to the wall of the stomach cavity comprises stapling outwardly projecting portions of the intragastric band between the first pair and between the second pair folds of stomach tissue.

4. The method of claim 1, wherein securing the intragastric band to the wall of the stomach cavity comprises placing anchors through outwardly projecting portions of the intragastric band between the first pair and between the second pair of folds of stomach tissue.

5. The method of claim 1, further comprising securing the intragastric band to the wall of the stomach cavity with sutures.

6. The method of claim 1, wherein securing the intragastric band comprises inserting barbs through the intragastric band between the first pair and between the second pair of folds of stomach tissue.

7. The method of claim 1, wherein securing the intragastric band to the wall of the stomach cavity comprises using an adhesive.

8. The method of claim 1, wherein the intragastric band includes a shape-memory alloy.

9. The method of claim 1, wherein the intragastric band is formed from a fabric material, and wherein securing the intragastric band comprises placing a connector through the fabric material and the first and second pairs of folds, wherein the connector is a staple, suture, hook or anchor.

10. The method of claim 1, further comprising positioning and securing a second intragastric band within the stomach cavity.

11. The method of claim 1, further comprising delivering the intragastric band to the stomach cavity in a collapsed configuration.

12. The method of claim 11, further comprising expanding the intragastric band into an expanded configuration.

13. The method of claim 12, further comprising applying a vacuum to the stomach cavity to bring the wall of the stomach cavity into contact with the outer surface of the expanded intragastric band.
