Abstract
Methods and devices to externally create a restriction on the stomach are described. In some embodiments, the devices are contoured to fit the stomach and can be further anchored to the stomach. In further embodiments, the degree of deployment of the extragastric restriction device is controllable after implantation. In other embodiments, specialized wires, catheters, ports, and trocars specific for placement of extragastric restriction devices are presented. In still further embodiments, systems are described in which adjustability of the devices is provided along with sensing and actuating ability.

18. A device to apply external compression to the stomach comprising:
-
a. A first structure with a first width and a second smaller width wherein the structure is constructed to bias toward the second smaller width unless a force is applied to maintain the first width. b. A second structure attached to the first structure and constructed from a material which enables force to be applied to the adjust the width of the first structure. - View Dependent Claims (19, 20, 21, 22, 23)
