A New Monopolar Radio Frequency treatment for anal fistulas
Fistura®, is a safe and minimally invasive RF procedure to treat anal fistulas. The flexible Fistura® catheter is inserted from the external opening and follows the tract of the anal fistula easily.
The blunt 4mm stainless-steel active tip facilitates the push through of the marked catheter without causing extra damage to the fistula wall.
A 4MHz radiofrequency wave delivers a controlled level of energy to the epithelialized tissue. This tissue will be destroyed in a controlled way and causes the fistula tract to collapse. The internal orifice of the fistula can easily be closed by a direct suture to keeptensions low in the mucous membrane.
The flexibility of the catheters is a key advantage that enables you to follow the tortuous tract of the anal fistula allowing to work end-to-end according to the diameter of the anal fistula.
A set of different sized catheters maximizes the energy penetration to a high degree, emitting radialenergy in a 3mm radius avoiding unnecessary tissue or muscle damage.
