A Endoscopic images of the gastric duodenal simulator (upper-left) and a porcine stomach after deployment of the novel gastro-duodenal flow restrictor (G-DFR) (upper-middle). The pig model used two hemoclips (arrowheads) to anchor the proximal flap of the G-DFR (upper-right). Radiographs showing the G-DFR in a simulator with peristalsis (lower-left) and the porcine stomach (lower-middle) after deployment of the novel G-DFR. Injected contrast slowly ran off through a 60-mm distal PTFE skirt of G-DFR (lower-right, arrowheads). B Line graphs showing the differences in relative weight loss percentages between the control and experimental porcine groups with the placement of a G-DFR with a 60-mm distal PTFE skirt (left). Bar graphs representing the difference of body weight between the control and the experimental group at each time point (right)
