The innovative Fistura® procedure is a minimally invasive, sphincter-sparing method of treating anal fistulae using radiofrequency catheter ablation. Highly flexible Fistura® catheters help users follow the fistula tract easily, sealing it along its entire length in a matter of minutes. Markings along the catheter serve as a convenient visual guide: simply withdraw the catheter by one marking every 12 seconds. Moreover, the catheter tip has a thermal effect radius of just 3 mm, which prevents damage to the surrounding tissue.
Fistura® catheters are available in four sizes, depending on the diameter of the anal fistula to be ablated:
