From: A novel human peristalsis-inspired 3D-printed gastroduodenal simulator to evaluate intragastric/duodenal metabolic devices: a proof-of-concept study

Fig. 1

Comparison of the changes in delayed gastric emptying volumes [ml] and percentage retention ratio of radio-opaque markers [%] in the simulator between the control group without intragastric/duodenal metabolic devices (dotted black line—with peristalsis, dotted gray line—without peristalsis as the standard reference model for delayed gastric emptying) and experimental devices including A commercial gastroduodenal covered metal stent with an 18 mm (purple line) or 20 mm (blue line) diameter, B G-DFR devices with a 30 mm (green line) or 60 mm (red line) PTFE skirt, and C an intragastric balloon (yellow line). D diameter of a stent, L length of PTFE skirt in G-DFR
