Abstract
Apparatus and methods are provided for forming a gastrointestinal tissue fold by engaging tissue at a first tissue contact point, moving the first tissue contact point from a position initially distal to a second tissue contact point to a position proximal of the second contact point to form a tissue fold, and extending an anchor assembly through the tissue fold near the second tissue contact point. Adjustable anchor assemblies, as well as anchor delivery systems, are also provided.
