Balloon tamponade devices and methods for their placement
First Claim
1. A balloon tamponade device for treating bleeding sites within the digestive tract, said device comprising:
- a tube having proximal and distal open ends;
a bridle attached to aid tube, said bridle adapted to extend up the esophagus to a traction means, said bridle adapted to secure and position said proximal open end of said tube within the digestive tract to permit normal feeding and swallowing function;
a first inflatable balloon mounted over said tube; and
a first inflation lumen opening into said first inflatable balloon, for directing pressurized fluid to inflate said first balloon.

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. In a device for treating esophageal or upper gastric bleeding sites, the balloons are an esophageal balloon and a gastric balloon. In a device for treating duodenal, pyloric or distal gastric bleeding sites, the balloons are a duodenal balloon and a gastric balloon. 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 The endoscope is used to check positioning and then withdrawn.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.
