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 system for reducing a volume of a stomach cavity, comprising:

a band having a plurality of segments with a radially inwardly facing surface, a radially outwardly facing surface, and top and bottom edges, and a plurality of radially outwardly projecting flexible belts connecting the segments where the belts form tissue folds attachment positions on the band;

wherein the band creates a stricture to reduce the volume within the stomach cavity when attached to a wall of the stomach cavity and contracted to a reduced diameter.

2. The system of claim 1 further comprising an adjustment mechanism located on a radially inwardly facing surface of a segment of the band for changing the diameter of the band.

3. The system of claim 2 further comprising an acquisition and fixation device having a cartridge and anvil connected to a tubular member for creating a dual fold of stomach tissue and fixing the dual fold of stomach tissue to the belt of the band.

4. The system of claim 3 further comprising vacuum ports on the acquisition and fixation device for drawing stomach tissue to create the dual folds of stomach tissue.

5. The system of claim 4 further comprising a removable septum disposed between the vacuum ports.

6. The system of claim 3 wherein the cartridge comprises a plurality of staples.

7. The system of claim 3 wherein the band is coupled directly to the acquisition and fixation device during delivery of the band.

8. The system of claim 3 wherein the band is sheathed on the acquisition and fixation device during delivery of the band.
