Abstract

Disclosed are methods and devices to apply therapies to the walls of an organ such as the stomach. Visualization means and access means are disclosed as are devices and apparatus which can be used to perform the disclosed procedures and methods.

Claims

1. An implantable device for treatment of obesity, said device comprising:

an expandable main body member configured to be positioned adjacent a portion of a stomach of a patient, within the abdominal cavity of the patient;

said expandable member being inflatable with pressurized fluid; and

an attachment tab extending from said expandable main body member.

2. The implantable device of claim 1, comprising at least one said attachment tab extending from a superior portion of said expandable member.

3. The implantable device of claim 1, comprising at least one said attachment tab extending from an inferior portion of said expandable member.

4. The implantable device of claim 1, wherein said attachment tab comprises a material that encourages tissue ingrowth.

5. The implantable device of claim 4, further comprising a border between said attachment tab and said expandable member, said border comprising a material that substantially prevents tissue ingrowth.

6. The implantable device of claim 1, wherein said attachment tab comprises at least one structural member therein, said at least one structural member being deformable to facilitate passage through a small opening in a patient, and wherein said at least one structural member returns to an undeformed configuration upon entering the abdominal cavity to orient said attachment tab toward a structure in the abdominal cavity to attach said attachment tab to.

7. The implantable device of claim 1, wherein said attachment tab is at least partially inflatable.

8. The implantable device of claim 1, wherein said attachment tab comprises a self-expanding attachment tab that is deformable to a compact configuration for passage through a minimally invasive opening in a patient, and wherein said attachment tab self-expands upon entering the abdominal cavity.

9. The implantable device of claim 8, wherein said self-expanding attachment tab comprises a self expanding wire frame.

10. The device of claim 1, further comprising a conduit in fluid communication with said expandable main body member, said conduit extending proximally from said expandable main body member.

11. The device of claim 10, wherein a portion of said conduit is travels through said attachment tab.

12. An multi-component implantable device for treatment of obesity, said device comprising:

an expandable main body member configured to be positioned adjacent a portion of a stomach of a patient, within the abdominal cavity of the patient;

said expandable member being inflatable with pressurized fluid;

an attachment tab connected to said expandable main body member wherein said attachment tab is fillable with a pressurized fluid.

13. The device of claim 12 wherein said connection between the expandable main body and the attachment tab is flexible.

14. The device of claim 12 wherein said connection between the expandable main body and the attachment tab is created with a suture.

15. The device of claim 12 wherein said connection between the expandable main body and the attachments tab is formed at least partially by sliding said attachment tab over said connecting component.

16. The device of claim 13 wherein said expandable main body and said attachment tab are separated by a distance.

17. A multi-compartment device to treat obesity comprising:

a first implantable expandable member configured to be attached to the abdominal wall and to conform to at least a region of the external surface of the stomach;

a flexible connector attached to said implantable expandable member and configured to fill said expandable member with a pressurized fluid;

a second expandable member attachable to said connector and fillable with a separate connecting tube.

18. The multi-compartment device of claim 17 wherein said second expandable member is outside of said first expandable member.
