Abstract

Several gastrointestinal surgery procedures are effective as treatments for metabolic disorders such as obesity and diabetes. Minimally invasive procedures including intra-luminal gastrointestinal implants have been proposed to mimic the anatomical, physiological and metabolic changes achieved by these procedures. Many of these designs include long sleeve like elements that prevent contact of food with the walls of the small intestine. It is desirable to have simple delivery systems that can place these implants under endoscopic guidance. However, in order to anchor these sleeve elements safely and reliably, the inventors have previously disclosed anchoring means that anchor the sleeves at the junctions of the stomach and the intestine or the stomach and esophagus.
