Methods and devices for maintaining a space occupying device in a relatively fixed location within a stomach
First Claim
1. A method of maintaining a space-occupying device in a fixed relationship relative to a patient'"'"'s stomach wall comprising the steps of:
- providing a space-occupying device;
introducing said space-occupying device into the patient'"'"'s stomach to a location adjacent an inner wall of the stomach;
bringing a first surface area of the inner wall of the stomach into approximation with a second surface area of the inner wall of the stomach; and
securing said first surface area to said second surface area such that the space-occupying device is retained at a fixed location relative to the stomach.

Abstract
Methods and devices for maintaining a space-occupying device in a fixed relationship relative to a patient'"'"'s stomach by manipulation of the stomach. In one variation, two or more regions of the stomach wall are brought into approximation with one another and secured together in a manner that secures a space-occupying device within the stomach of the patient. In another variation, two or more regions of the stomach wall are wrapped around a space-occupying device to maintain the position of the space-occupying device relative to the stomach wall. In another variation, a system having a space-occupying member and a locking member capable holding the space-occupying member against the inner wall of the stomach are provided. In a further variation, a pouch is created within the stomach that receives and retains a space-occupying device.

14. A space-occupying system for deployment of a space-occupying device inside a patient'"'"'s stomach comprising:
-
an expandable member adapted for placement inside the stomach, said expandable member having an opening, said expandable member further having a first side and a second side, and said opening provides a channel running from said first side to said second side; and
a locking member adapted for placement outside of the stomach, wherein said locking member has a diameter greater than a largest diameter of the opening - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. A method of anchoring a space occupying device on a patient'"'"'s stomach wall comprising the step of:
-
providing an inflatable space-occupying device having a passageway there through;
introducing said inflatable space occupying device into the stomach to a location adjacent to a first region of the stomach wall;
placing an spherical member adjacent the first region on the outside of said stomach;
forcing said spherical member and said first region of the stomach wall through the passage way of the space-occupying device while the space-occupying device is in a deflated state; and
inflating said space occupying device and trapping said spherical member, thereby securing said space-occupying device to the patients stomach wall. - View Dependent Claims (24, 25)

26. A method of maintaining a space-occupying device within a patient'"'"'s stomach comprising the steps of:
-
creating a pouch within the stomach; and
introducing a space-occupying device into the pouch, wherein the pouch is dimensioned to receive and retain the space-occupying device. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33)

34. A method of assisting weight loss in a patient comprising the steps of:
-
a) creating a pouch within the patient'"'"'s stomach;
b) selecting a first space-occupying device adapted for placement and retention within the pouch, the first space occupying device having a passageway extending through the device, and a cavity within the device and in communication with the passageway, the cavity having a first defined volume;
c) introducing the space-occupying device into the created pouch such that the passageway is oriented in alignment with the patient'"'"'s esophagus;
d) monitoring the patient'"'"'s weight loss, and, if warranted e) replacing the first space-occupying device with a second space-occupying device adapted for placement and retention within the pouch, the second space-occupying having a passageway extending through the device, and a cavity within the device and in communication with the passageway, the cavity having a second defined volume, such that the passageway is oriented in alignment with the patient'"'"'s esophagus, the second defined volume of the second space-occupying device being different than the first defined volume of the first space-occupying device.

35. A method of assisting weight loss in a patient comprising the steps of:
-
a) creating a pouch within the patient'"'"'s stomach;
b) selecting a space-occupying device adapted for placement and retention within the pouch, the space occupying device having a passageway extending through the device, and a cavity within the device and in communication with the passageway, the cavity having an adjustable volume;
c) introducing the space-occupying device into the created pouch such that the passageway is oriented in alignment with the patient'"'"'s esophagus;
d) monitoring the patient'"'"'s weight loss, and, if warranted e) adjusting the cavity volume of the space-occupying device.
