The Thermedical® Ablation System actively forces thermal convection – an efficient and controllable mechanism of heat transfer—by the simultaneous injection of heated saline and application of the RF energy.

  • Convection v Conduction

  • Traditional ablation technologies rely on passive thermal conduction, an inefficient process that requires significantly more energy to heat tissue further away from the electrode, burning tissue closer to the RF electrode source. 

 

  • The Thermedical Ablation System injects heated saline into the tissue adjacent to the electrode while RF energy is being applied. The injected saline carries energy deep into the tissue, increasing the heat transfer capacity of the tissue by a factor of 20 or more.  This method of heat transfer is much more efficient than conduction because it can carry heat much deeper and in a more uniform manner than conduction. 

 

  • SERF alters the physics of heat transfer in the tissue, thereby reducing the amount of time and energy required to heat the target tissue to the desired level.  

 

  • A single probe or catheter can make large, deep, and uniform lesions.  

 

  • The temperature profile within the treatment zone is nearly isothermal (constant), ensuring that all tissue is given the same thermal dose.
