Recently, F Care Systems extended its product range with a specially designed catheter for efficient removal of the incompetent saphenous veins. This catheter (CR45i) utilises the same RF energy from the EVRF generator through its robust yet totally flexible length, at the end of which is a 0.5cm tip from which the energy is emitted. The catheter is inserted along the length of the vein and is withdrawn in increments producing occlusion of the entire vein. Other similar systems have larger treatment tips but the CR45i is specifically designed to enable passage through the most tortuous of veins and requires a shorter tip in order to do so. Procedure times are comparable to similar treatments since, whilst withdrawal is in smaller increments, there is no waiting time for the tip to heat up.
As with all features of the EVRF device, this treatment is minimally invasive, preventing unpleasant and possibly unsafe side effects such as pigmentation defects, superficial Thrombophlebitis or deep venous thrombosis. Patients experience minimal discomfort and normal activity can be resumed within one day.
Brief Introductory Guide to using the CR45i
Insert a 6F introduction needle into the saphenous vein;
Insert a guide wire through the needle into the vein. Open the vein by sliding a dilatator over the guide wire.
Replace the guide wire with a CR45i catheter and move the catheter up the vein. Position the catheter correctly with echo Doppler guidance.
Depress the foot pedal to send a radio frequency signal into the vein. The warning tones and lights on the EVRF tell when the catheter needs to be retracted. Repeat the procedure until the end of the vein.
