Fistura -Radiofrequency Treatment Device of Anal Fistulas
The Fistura® procedure uses radio frequency thermocoagulation to treat anal fistulas utilising the emission of electromagnetic waves at a very high frequency (4MHz), similar to the principle of a microwave. This minimally invasive technique seals the fistula tract without having to open the anal sphincter and is performed in a day-case or the outpatient setting, with minimal discomfort for the patient, allowing an immediate return to daily activities.
For the Practitioner
- Quick and efficient minimally invasive procedure
- Simple to perform
- Excellent alternative to more invasive techniques
- Highly effective on patients with Crohn’s disease
- Minimal post-operative care
- Safe control of energy, avoiding damage to adjacent tissue or muscles
For the Patient
- Minimally invasive
- Quick procedure performed in a day-case or outpatient setting
- Comparatively little or no pain
- Minimal post-operative care
- Immediate return to daily activities
Radiofrequency thermocoagulation

The four phases of thermocoagulation
- Ionic agitation
- Vaporization and dehydration of the tissue
- Thermal destruction
- Dehydration of the tissue and Coagulation
The flexibility of the catheter is a key advantage to easily follow the path of the anal fistula – it will allow you to close the fistula along its entire length.
The catheters maximise energy penetration to a high degree, emitting a radial wave within a radius of 3 mm thus avoiding damage to adjacent tissue or muscle.
Depending on the diameter of the anal fistula, a range of different catheter sizes is available (from 6F to 9F).
