For the sphincter-preserving occlusion of fistulae-in-ano

Lightguide Fistula Probe

The Fistula Probe allows easy access into a small and curved fistula tract for the permanent occlusion of complete fistulae-in-ano which are pre-conditioned by seton drainage (Parks Types I-IV) and at the non-inflammatory stage.

Inside the fistula tract, the radial emission of laser energy destroys remnants of the fistula epithelium and leads to the controlled shrinkage of surrounding tissue. Thus, the fistula tract is gently obliterated with only minimal side effects on the anal sphincter.

There are marking lines on the Fistula Probe for easy and precise control over its position and pullback velocity.
