Abstract

In one embodiment, a pressure sensing system is described which transmits data to a patient management system external to a patient. The pressure sensing system can rigidly couple to an implantable port or flexibly couple to an implantable port. In some embodiments, the pressure sensing system communicates with a hydraulic actuating system. In some embodiments, the pressure sensing system is implantable and comprises a circuit capable of wireless transmission through the skin of a patient to an external receiver which is part of a patient management system. A patient management system is described which receives up to date as well as historical data from the pressure sensing system and manages the these data in the context of a patient database. In some embodiments, an extragastric balloon is described in which the balloon is contoured to fit a portion of the stomach but not circumscribe the stomach. In some embodiments, electroactive polymers or nitinol structures are utilized to create restriction on the stomach in response to food boluses entering the stomach. In some embodiments, a nasogastric connector is described with two expandable structures translateable toward and away from one another so as to create pressure between two organ lumens when brought toward each other and fixed with respect to one another.

Claims

1. A device to compress the stomach from the outside comprising:

a first non-expanded configuration and a second expanded configuration wherein said device is adapted to be placed in between the peritoneum and the anterior wall of the stomach and wherein said device is configured to create stomach restriction when in its final position and when in its expanded configuration.

2. The device of claim 1 wherein said device is adapted and sized to fit through a percutaneous conduit.

3. The device of claim 1 wherein said device is further adapted to attach to the abdominal wall.

4. The device of claim 1 wherein said device is further adapted to attach to the abdominal wall with a fastener.

5. The device of claim 1 wherein said device is adapted to slide over a flexible connector to reach said final position.

6. The device of claim 1 wherein said device is adapted to attach to the anterior wall of the stomach or a surrounding structure using a suture;

and, wherein said device is adapted to slide over the suture.

7. The device of claim 1 wherein said device is adapted to attach to the anterior wall of the stomach and the abdominal wall simultaneously.

8. The device of claim 1 wherein said device is inflatable.

9. The device in claim 1 wherein said device in said expanded configuration substantially covers the external surface of the stomach.

10. The device of claim 1 wherein said device is sized from about 20-50 centimeters along the length of the stomach and from about 1-30 centimeters along the width of the stomach.

11. The device of claim 1 wherein said device further comprises an attached mesh to facilitate attachment to the stomach or surrounding structures.

12. The device of claim 1 wherein said device further comprises an attached anchor.

13. The device of claim 1 wherein said device further comprises a support structure.

14. The device of claim 1 wherein said device further comprises a support structure;

and, wherein said support structure is more rigid than the device; and

, wherein said device is inflatable.

15. The device of claim 1 wherein said device further comprises a support structure wherein said support structure is adapted to apply force to the exterior region of the stomach to constrict the stomach.

16. The device of claim 1 where said device comprises a balloon with multiple compartments.

17. The device of claim 1 wherein said device further comprises a support structure with shape memory.

18. The device of claim 1 wherein said device further comprises a supporting structure which increases the rigidity of one portion of the device.

19. The device of claim 1 wherein said device is inflatable and wherein said device can circumscribe a portion of the stomach ranging from one-quarter of the stomach to ¾

of the circumference of the stomach when said device inflated.

20. The device of claim 1 further comprising an adjustable component wherein said adjustable component allows for different levels of expansion depending on the amount of fluid within the adjustable component.
