Definitions

  • the invention is related to a system to seal the great saphenous vein , small saphenous vein and perforator veins using a thermal ablation method in the treatment of venous insufficiency (treatment of varicose or varicose veins) .
  • Venous insufficiency is defined as a disease that is caused by reflux and leakage arising from the enlargement of the great saphenous vein , small saphenous vein and perforator veins that run parallel to the deep vein (femoral vein) depending on insufficient functioning of the venous blood vessel valves.
  • said veins that are leaking are sealed by means of endovenous (intravenous invasive operation) interventions using thermal ablation methods.
  • RF (radiofrequency) ablation technology is a known technology.
  • I t is constituted of an ablation catheter that is coupled to an RF generator. The generator adj usts the application time and the thermal energy that is to be delivered into the vein and it has a screen which shows certain parameters.
  • the generator receives energy from the mains and it is a large device. I n every procedure it has to be positioned inside the surgical theatre or operation room .
  • the ablation catheter is formed of a jack that is coupled to the generator, a controller and a solenoid at the tip thereof.
  • the solenoid is the section that applies thermal energy.
  • the catheter is delivered intravenously and is submitted to the area to be treated and the solenoid performs the ablation .
  • the invention is related to a disposable ablation catheter that can be coupled to a solenoid catheter having a controller and a battery operated system without the necessity for an RF generator.
  • Figure 1 General view
  • the invention is constituted of three main parts having a solenoid tip, control unit, and a battery.
  • the solenoid tip is 5cm in length and it is coated with polytetrafluoroethylene (PTFE) .
  • the temperature sensor thermocouple
  • the control unit provides a standard treatment option .
  • the temperature can be adj usted to be between 120-140°C and the application time to be between 10-20 seconds via the control panel. These parameters are shown digitally.
  • the battery is a lithium battery and it is able to produce the required energy even without a generator.
  • the catheter (1) is delivered to the area to be treated.
  • the treatment parameters are set.
  • the catheter is retracted every 5 em's and treatment is applied in accordance with the related temperature and time parameters.
  • the device pauses for 1 second and the catheter (1) is retracted during this one second pause. Following this the solenoid tip is re-activated and the ablation process is continued.
  • the green activation button is pressed again and the catheter (1) is shut down and the procedure is completed.
