OPTIMIZING THE OPERATION OF AN INTRA-GASTRIC SATIETY CREATION DEVICE
First Claim
1. A method for determining an optimum control parameter of a distension system for causing distension in a stomach, comprising:
- a. providing a distension device having an undeployed shape for delivery within a hollow body and one or more deployed shapes for implantation therein, said member having sufficient rigidity in its deployed shape to exert an outward force against an interior of the hollow body so as to bring together two substantially opposing surfaces of said hollow body, and a means for changing the deployed shape of said member while implanted within said hollow body.b. implanting the distension device within a body;
c. changing the shape of distension device to a first deployed shape;
d. determining the value of a control parameter of the distension system; and
e. changing the shape of distension device to one or more second deployed shapes until the control parameter is substantially convergent as a function of time.

Abstract
A method for determining an optimum control parameter of a distension system for causing distension in a stomach. The method includes the step of providing an implantable distension system for causing distension in a stomach, the system including an adjustable distension device configured to form a distension in a stomach. The method also involves adjusting the distension device, and determining the value of a control parameter of the distension system. The method also involves repeating the steps of adjusting the distension device and determining the value of the control parameter until the control parameter is substantially convergent as a function of time.
