Product and method for dilation of strictures in the upper gastrointestinal tract.
Use of the BougieCap
The BougieCap is an endoscopic attachment cap, which is introduced into the upper gastrointestinal tract under endoscopic observation to dilate/expand strictures.
The BougieCap allows direct visual control during the dilation. The tension on the tissue is visible while passing the stricture with the cap, thereby avoiding overstretching. Moreover, the procedure time is reduced due to less instrument change. The evaluation can be done directly after the dilation thanks to the attached transparent cap.
The distal end of the cap has three holes: two of them (lateral) for air insufflation and suction and one (center) for the insertion of a guide wire.
One package contains three caps of the same size, which are separately packaged.
Dimensions and specifications
Caps are available in different sizes (7, 8, 10, 12, 14, 16) and they will be attached onto the endoscope.

Application of the BougieCap
Dilation of strictures
Step 1: Guiding the endoscope with the attached BougieCap up to the stricture.
Step 2: Carefully sliding the endoscope through the stricture using gentle rotations under visual control. If there is too much resistance or the tissue visibly tears, ceasing the dilation via bougie or, if required, selecting a narrower diameter.
Step 3: Successful passage.
After successful passage, pulling the endoscope back out of the body. If required, fitting the next largest BougieCap, as described above, until the required diameter is achieved.
