EVRF (Endo Venous Radio Fequency)

EVRF® is a all-in-one device for all types of varicose vein treatments. F Care Systems recently developed a probe for EVRF® hemorrhoid treatment making it possible to treat varicose veins and hemorrhoids with one device. The appropriate catheter or needle is connected to the generator for treatment. The catheter choice is made based on the size of the vein to be treated.



Varicose veins, regardless of their type, impacted millions of people’s quality of life. EVRF is an appropriate technique for removal of varicose veins. It can treat all varicose vein types from saphena manga to the smallest spider veins with a special type catheter. Varicose treatment with EVRF is realistic and causes minimal discomfort and a perfect clinical and aesthetic appearance.

Endovenous, Colalteral, and Telegeniectasia treatments with one device.

Advanced Radio Frequency (RF)Technology:

  • A high frequency signal is produced by the central unit.
  • This signal is introduced within the vein wall with a catheter or a needle. The preference of needle or catheter diameter is adapted according to the vein measurement.
  • RF energy is monitored with the central unit resulted in effective thermocoagulation and removal of the vein. This effect is completely local by causing minimal damage around the tissue.

“Soft and fast, less expensive than current technologies and it works well”

Dr. T. Beyens, Centre Hospitalier Inter Regional Edith Cavell Brussels Belgium

Transcutaneous Treatment (veins up to 1 mm)

Small veins in face or legs are treated with specially designed thermo-coagulation needles and a needle holder:

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

With its sharp needle tip, it does not cause pain, it causes only mild stains that would disappear within a few days. Minimal or no bruising or swelling was reported with EVRF.

Clinical Studies on Thermocoagulation

Dr. Jean-Luc Richard published the results of a clinical trial on thermocoagulation showing that with this technique teleangiectasis treatment is realistic and does not have any side effects.

In studies he conducted between the years 99 and 05 in 7000 thermocoagulation sessions, Dr. Jean-Marc Chardonnea provided evidence for:

  • It is effective for all vein problems including the ones that have a diameter of less than 0.9mm and that cannot be treated with sclerotherapy.
  • When the right protocol is followed, more than 80% veins were permanently removed.
  • Appropriate for all skins.
  • No side effects were found, only temporary micro scab
  • No pigmentation change, necrosis or burning.

Varicose veins from 1 to 7mm (CR30i):

Reticular, collateral and perforating veins can be treated with CR30i catheter of F Care Systems. Catheters are very flexible which allows the following of the vein direction. The soft entrance is provided by the advanced coating materials around the catheter. The uninsulated tip sends the high frequency signal into the vein wall. This would cause the vein to coagulate and disappear.

Catheter is applied with a sterilized handle. Moving the wheels of the handle would move the catheter towards the inside of the vein.

4 Stage Procedure;

  • The entry needle is inserted in the vein.
  • The position of the entry needle is changed with catheter by using the sterilized handle
  • The catheter is moved on the vein by sliding the handle wheels.
  • The pedal is pushed and pulled to send a RF signal into the vein. The vein will be coagulated and disappear.

Saphena Veins (CR45i):

Today, F Care Systems expanded its product range with a wide catheter to effectively destroy saphena manga. Thermocaoagulation of saphea manga occurs in sequences of segments that are in 0.5 cm length. With this procedure, the whole vein is destroyed in 5-10 minutes. The complete destruction of veins are seen in all trials.

The destruction of Saphena Manga with EVRF has minimal invasive, unpleasantly protective and unsafe side efects such as pigmentation defects, superficial thrombophlebitis or deep vein thrombosis. Patients experience some discomfort and can go back to their normal functions within one (1) day.

The coating material preferred around the flexible filling provides a soft and fast entry.

4 Stage Procedure;

  • 6F entry needle is inserted in the saphena magna vein.
  • A guide wire is inserted through the needle in the vein. A dilatator is slided over the guide wire and the vein is opened.
  • The guide wire is placed with a CR45i catheter again and the catheter is moved upward in the vein. Echo Doppler should be placed correctly with its guide.
  • Pedal is pressed to transmit an RF signal in the 0.5 cm vein segments. One warming signal would allow the RF energy to be imaged within the vein that is entered. After this, the catheter is removed and the procedure is followed in the next segment.
