摘要：
Devices, systems, and methods for treating gastro-esophageal reflux disease (GERD) include anti-reflux valves and retainers for securing them within the lumen of the esophagus, stomach, or a hiatal hernia. The retainers contain inflatable balloons, some of which may be enveloped by a flexible shell that is used to secure the balloon to tissue. Methods are described for treating GERD patients who (1) have no hiatal hernia, (2) have a hiatal hernia that is fixed in place, or (3) have a hiatal hernia that slides above and below the diaphragm. Methods are also described for delivering GERD-treatment devices to their target locations within the patients gastrointestinal tract.
