ABSTRACT:
Several methods and apparatus are available for treating patients that suffer from both gastro-esophageal reflux disorder and hiatal hernias. In order to treat these patients, an endoscopic probe may be used to push the herniated stomach below the diaphragm. In some embodiments, a two-part stent comprising a funnel stent and a reverse stent may be deployed to prevent a future re-herniation of the stomach and to reduce the annulus of the lower esophageal sphincter. In some embodiments, a reverse stent with perforating barbs may be deployed, in which the barbs penetrate the esophageal wall and attach to the diaphragm. In some embodiments, the crus muscles may be sutured together to reduce the hiatus size and a reverse stent may be deployed to reduce the annulus of the lower esophageal sphincter.
