Use of the BougieCap
The BougieCap is an endoscopic attachment cap, which is introduced into the upper gastrointestinal tract under endoscopic observation to dilate strictures and stenoses.
The BougieCap
The BougieCap allows for immediate visual control during bougienage. The tissue tension produced by the cap passing through the stenosis is made visible, so that overstretching is easier to prevent.
Due to the two-stage design, the dilation is performed extremely gently and precisely in millimetre increments.
The success of the dilation can be assessed directly with the cap in place. Since the need to change instruments is eliminated, this procedure saves time.
The cap has three holes at the distal end: the central hole in the tip allows for the use of the BougieCap with a guide wire (max. 1 mm/0.038 in). The two lateral orifices are designed for air insufflation, suction and irrigation even with the cap in place.
Due to the resource-saving design, there is up to 99 % less waste with the BougieCap as compared to conventional dilation methods*.
BougieCap pack contains three caps of identical size, each in individual sterile packaging.

Dimensions and specifications
The BougieCap is available in different sizes with two dilation diameters per cap and is to be attached distally to the endoscope using the enclosed tape.

Application of the BougieCap
Step 1: Guide the endoscope with the BougieCap attached to just before the stenosis.
Step 2: Carefully advance the endoscope and the smaller dilation plateau into the stenosis through gentle rotational movements and under visual control. If there is too much resistance or if tissue tearing can be seen, discontinue the bougienage or choose a smaller diameter according to need.
Step 3: If necessary, advance beyond the second dilation plateau to extend the bougienage to the second dilation diameter.
Step 4: Successful passage.
Example *:
Guide the endoscope with the attached BougieCap until just before the stenosis.
Carefully push the BougieCap up to the first dilation plateau using gentle rotations.
Then, if required, continue pushing until it reaches the second plateau.
Successful passage.
