At what temperature does the ClosureFast catheter operate?

The ClosureFast catheter operates at a temperature of 120 °C. This specific temperature is critical for effectively delivering radiofrequency energy to the tissues during endovenous thermal ablation procedures. Heating the catheter tip to this temperature facilitates the controlled shrinkage of the vein walls, leading to their closure. The precision of temperature control is essential to ensure the procedure's safety and effectiveness, as higher temperatures could cause excessive thermal damage, while lower temperatures might not achieve the desired tissue response. By standardizing the operational temperature to 120 °C, the ClosureFast system allows for consistent and reliable outcomes in treating venous conditions.
