1. A system adapted for inducing satiety in a patient comprising:
- a device body capable of changing configuration from a relatively smaller-profiled undeployed configuration to a relatively larger-profiled deployed configuration, sized to be introduced through a percutaneous conduit when in the undeployed configuration;
a porous structure on the device body to facilitate attachment of the device body to the outside of a gastrointestinal organ or to an abdominal wall, wherein the porous structure comprises polypropylene mesh or a metal alloy; and
an inflatable structure connected to or forming a part of the device body.

Abstract
Disclosed are methods and apparatus for implantation into the walls of an organ such as the stomach. Deformable or inflatable anchors with a connector between are used to pull the walls of the organ together, or to implant devices in the wall of the organ. Also disclosed are surgical instruments useful in practicing the disclosed methods.
