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

1-20. -20. (canceled)

21. A device for application to the external stomach surface of a patient comprising:

i. A first portion expandable from a collapsed state to an expanded state

ii. A second portion coupled to the first portion contoured to fit an external portion of the stomach without encircling the stomach

iii. A third portion coupled to the device which is slideable over a flexible connector comprising a proximal end and a distal end.

22. The device of claim 21 wherein first portion is a balloon.

23. The device of claim 22 further comprising a fluid communication line in contact with said balloon.

24. The device of claim 23 wherein said communication line and said connector are the same structure.

25. The device of claim 21 wherein said first portion and said second portion are the same portion of the device.

26. The device of claim 21 wherein said second portion has a radius of between 0.25 and 5 centimeters and is curved to fit the cardia of the stomach when said first portion is in its expanded state.

27. The device of claim 21 wherein said second portion is between 5 and 30 centimeters.

28. The device of claim 21 wherein the connector further comprises an anchor at its distal end.

29. The device of claim 21 wherein said device further comprises a sensor.

30. The device of claim 23 wherein said communication line further comprises a sensor.

31. The device of claim 21 further comprising an implantable port which communicates with the expandable second portion.

32. The device of claim 21 wherein said first or said second portion further comprises an electroactive polymer.

33. A system comprising:

a. A device expandable from a first configuration to a second configuration wherein said device is contoured to partially surround a portion of the stomach without fully circumscribing the portion of the stomach;

b. A connector coupled to said device and operable to adjust the degree of expansion between the first configuration and the second configuration;

c. A port in communication with the connector said port operable to be accessed intermittently through the skin of a patient.

34. The system of claim 33 wherein said device comprises a balloon.
