Abstract
Barrett's esophagus is a serious complication of GERD. It is characterized by the replacement of the normal stratified squamous epithelium lining of the esophagus by simple columnar epithelium with goblet cells (which are usually found lower in the gastrointestinal tract). A method comprising deploying multiple stents to cause pressure ischemia and subsequent necrosis of the mucosal layer of the esophagus which is affected with the Barrett's disease is disclosed. A pair of implantable stents having specific characteristics is disclosed which can be deployed in the esophagus to cause necrosis of the mucosal layer of the esophagus through induction pressure.
Claims20
A method for treating Barrett's esophagus in a patient comprising:
- identifying an affected region in the esophagus;
- deploying an at least partially uncovered first stent within the esophagus wherein the first stent overlaps at least the entire affected region in the esophagus;
- leaving said first stent within the esophagus for a first predetermined time period;
- deploying an at least partially covered second stent within the esophagus after said predetermined time period such that the second stent is positioned within the first stent, thereby positioning the first stent between the second stent and the affected region in the esophagus, and extends beyond the first stent by a predefined distance;
- and,
- removing the first stent and second stent after a second predetermined time period.
