Benefits of technology

[0013] The present invention provides devices, methods and systems for obstructing or occluding a pyloric valve to provide weight loss and in some cases treat or ameliorate obesity. Devices are generally delivered into the stomach where they expand or are expanded to partially and/or intermittent...

Problems solved by technology

By partially or intermittently obstructing or occluding the pyloric valve, contents of the stomach (i.e., food) are retained longer in the stomach, thus causing a patient to feel full s...

Embodiment Construction

[0070]FIGS. 1A to 1C are cross-sectional views showing the expansion, respectively, of one variation of a pyloric corking device which is designed to partially and / or intermittently obstruct a gastric opening, particularly the pyloric valve. In this particular variation, FIG. 1A illustrates the device 4 in an unexpanded or uninflated state and ready for delivery and / or insertion into the pyloric valve. FIG. 11B shows the distal occlusion member 14 in an expanded state. In use, once the device 4 has been placed, e.g., in the pyloric region or beyond, the distal occlusion member 14 (or “retaining member”) may be inflated through the influx of any number of biocompatible fluids or gases, e.g., saline, water, air, nitrogen, etc., through the tubing 8 leading to the inflation port 6, which may be self-sealing. Tubing 8 may include any number of delivery tubes such as catheters, endoscopes, etc.

[0071] The distal occlusion member 14 may be configured to inflate before the inflation of pro...

Abstract

Methods, devices and systems facilitate gastric retention of a variety of therapeutic devices. devices generally include a support portion for preventing the device from passing through the pyloric valve or esophagus wherein 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 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.
