Claim:
1. A gastrointestinal implant device comprising: a planar proximal element configured to reside in a stomach to resist distal migration; a distal element configured to reside in an intestine to resist proximal migration; and one or more tethers coupling the planar proximal element to the distal element; wherein the planar proximal element is between 40 mm and 100 mm in size in a first dimension, and is between 0.5 mm and 15 mm in size in a second dimension, orthogonal to the first dimension; and wherein, in normal use of the implant device, a central longitudinal axis of the planar proximal element, perpendicular to a plane in which the planar proximal element lies, is substantially perpendicular to a central longitudinal axis of a lumen of a pyloric sphincter of the stomach.
