EVRF® – Endovenous Radiofrequency ablation

Radiofrequency ablation
Perforating Veins, Collateral Veins, Reticular Veins, Spider Veins, Petechia, Rosacea, Saphena Magna and Hemorrhoids.

“All in one device for the treatment of varicose veins and hemorrhoids.”

zoals de EVRF zou moeten zijnThe EVRF® is an all-in-one device for the treatment of all sorts of varicose veins. F care systems has recently developed a probe for an EVRF® treatment of hemorrhoids which makes the treatment of varicose veins and hemorrhoids possible with one single device. For the treatment the appropriate catheter or needle is connected to the generator. Which catheter needs to be used depends on the size of the vein that has to be treated.

Advantages

For the patient

No pain during and after treatment.
No pigmentation or allergic skin reaction.
No dermatological reaction due to a chemical compound.
High aesthetic result.

For the doctor

Easy to use.
Permanent occlusions.
All parts of the body
Semi-sterile environment (private practice).
No chemical agent in the body.
Collateral, peripheral and perforating veins can be treated.

Device

A versatile generator.
Wide range of treatments.
Fable investment cost.
No damage to the surrounding tissues.
Minimally invasive treatment
immediate return to his daily activities.

 

Thermocoagulation

The ablation of varicose veins is based on thermocoagulation. The principle of thermocoagulation is heating the vein, which makes it coagulate. This rise in temperature is achieved by sending a high frequency pulse into the tip of the needle or catheter. The rise in temperature causes the proteins in the arterial wall to solidify and make the vein disappear. Due to the isolation of the needles and catheters, the effect is very local, causing minimal damage to the surrounding tissue.

EVRF® generator

The catheter or the needle required for the chosen treatment is connected to the central unit, which generates a high frequency signal that is transmitted to the intima of the vein wall.

Precise control of the EVRF® generator

The radiofrequency energy is closely monitored with the central unit. The duration of the pulse can be set from 0.1 to 1 seconds in steps of 0.1 second. The pulse power can be selected in steps of 5%, with the cap sense touch screen (no touch pen needed). The combination of both settings will allow for very precise control over the amount of energy administered, resulting in effective thermocoagulation and closing of the vein.

Needles and catheters

We work with various needles and catheters:

  1. Small veins up to 1 mm.
  2. Big veins from 1 to 5 mm.
  3. Great Saphenous Vein (bigger than 5 mm).

1.Transcutaneous treatment (veins up to 1mm)

Small veins on the face or on the legs are treated with a needle holder in combination with the specially designed thermocoagulation needles:

  • K3i needle with diameter 0.075mm (mostly used for facial treatment).
  • K6i needle with diameter 0.150mm (mostly used for treatment of legs).

With the extremely sharp needle tip, the treatment is almost painless and causes only very light stains that completely disappear within a few days. With the EVRF®, very little to no bruising or swelling has been reported. You can see here how easy this treatment is.

2. CR12i and CR30i (veins of 1 to 5mm)

Large varicose veins from 1 to 5mm are treated with a specially designed hand catheter. The catheter is manipulated with a sterilized handset. Scrolling the handset’s wheel will move the catheter into or out of the vein. These handsets are easy to hold and control, very flexible and the perfect insulation makes it possible to slide the catheter into a varicose vein and coagulate the vein from the inside. The catheter will be inserted into the vein and retracted step by step until the vein is completely closed. This thermocoagulation effect is similar to the treatment of the great saphenous vein.cr12i-en-cr30i-evrf

To see those catheters in action, you can watch the animation video and the treatment video below.

 

3. CR45i (Great Saphena Vein)

For the treatment of the Great Saphenous Vein, the CR45i catheter is used. Its 5mm non-isolated tip and its flexibility allow for a smooth insertion. The catheter will be pulled Magna ablation with EVRF® is minimally invasive, preventing unpleasant and possibly unsafe side effects such as pigmentation defects, superficial thrombophlebitis or deep venous thrombosisck gradually until the entire vein is closed. This procedure will take about 5 minutes. Patients experience minimal discomfort and normal daily activities can be resumed within one day.
