#$%^&*AU2012200476A120120216.pdf#####ABSTRACT Methods, devices and systems facilitate intermittent and/or partial obstruction of a pyloric valve. Devices generally include a support portion for preventing the device from passing through the pyloric valve and a tissue engagement portion for contacting tissue 5 adjacent the pyloric valve to obstruct the valve. Some embodiments also include a positioning member extending from the tissue engagement portion for helping position the device for obstructing the valve. A retaining member may optionally be included on the distal end of the positioning member for further maintaining a position of the device in the stomach. Some embodiments are deliverable into the stomach through the esophagus, either by swallowing or 10 through a delivery tube or catheter. Some embodiments are fully reversible. Some embodiments self-expand within the stomach, while others are inflated or otherwise expanded. FIG. 9D10/22 78 92 FIG. 9C 74 82 8 76 78 92 .FIG. 9D 82 74 86 76 78 80 FIG. I0A 6 74 76
