1. A method of reducing the effective volume of a patient'"'"'s stomach cavity comprising:
- implanting a first magnetic device on an inner surface of the stomach cavity at a first location; and
implanting a second magnetic device on an inner surface of the stomach cavity at a second location, the first and second locations being selected to be across the stomach cavity from one another but to be movable toward one another across the stomach cavity to allow the first and second magnetic devices to contact one another as a result of magnetic attraction between the first and second magnetic devices.

Abstract
The effective volume of a patient'"'"'s stomach cavity can be reduced by implanting at least two magnetic devices in the stomach at different locations on the stomach wall. The magnets cooperate with one another magnetically to change the effective volume of the stomach. For example, the magnets may magnetically attract one another to pull in portions of opposite side walls of the stomach. The magnetic devices may be implanted non-surgically (e.g., via one or more catheters introduced into the stomach cavity via the patient'"'"'s mouth and esophagus). The magnets may be removable to reverse the treatment. Removal may be non-surgical.

7. Apparatus for reducing the effective volume of a patient'"'"'s stomach cavity comprising:
first and second magnetic implants at respective first and second stomach wall locations that are across the stomach cavity from one another but that are movable toward one another across the stomach cavity to allow the first and second magnetic implants to contact one another as a result of magnetic attraction between the first and second magnetic implants, resulting in an application of force to the stomach wall locations. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
