Methods for placement of balloon tamponade devices

Abstract

Balloon tamponade devices for treating bleeding sites within the upper digestive tract (e.g. esophageal or upper gastric bleeding sites, or duodenal, pyloric or distal gastric bleeding sites) comprise a tube having proximal and distal open ends and at least one inflatable balloon mounted over the tube. Preferably, two balloons are mounted over the tube, and inflation lumens are provided for each. A bridle is attached to the tube, and is adapted to extend up the esophagus to allow the device to be secured in place having the proximal open end of the tube positioned within the digestive tract to allow for normal feeding and swallowing functions. A method for placing a balloon tamponade device as generally described above is also described. The device is backloaded onto an endoscope by passing the endoscope through the open ends of the tube. The endoscope is then passed through the mouth and down the esophagus and used to examine the esophagus and/or other portions of the digestive tract to determine whether or not treatment is required. If treatment is required, the device is advanced along the endoscope and down the esophagus, and the balloon(s) of the device is (are) positioned and inflated to treat the bleeding sites. The endoscope is used to check positioning and then withdrawn. Thereafter, the bridal can be positioned through the nose and connected to a traction device. Methods for delivering detachable coatings to bleeding sites for treatment thereof are also described.
