Fistura® RF catheters
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:
| Size (French) | 6F | 7F | 8F | 9F |
|---|---|---|---|---|
| Catheter diameter | 2 mm | 2.33 mm | 2.66 mm | 3 mm |
| Catheter weight | 40 g | 41 g | 42 g | 43 g |
| Product REF | 05FIS6F | 05FIS7F | 05FIS8F | 05FIS9F |
