Endovenous laser treatment of varicose veins
SEDI-ATI manufactures silica fiber optic probes with a radial emission for endovenous laser thermal ablation treatment of varicose veins.
The endolaser: the most effective and least traumatic procedure
Today, minimally invasive endovenous laser procedures progressively replace conventional venous surgery. Indeed, endolaser is globally recognized as the most efficient and atraumatic procedure for treating the incontinence of the great saphenous vein (GVS) and the small saphenous vein (SSV). Moreover, the endovenous laser thermal ablation of varicose veins at 1470 nm usually makes the post-surgery course shorter and less painful than traditional surgery.
Treatment process by introduction into the vein
The phlebologist operates under echographic control. The fiber probe, of very small caliber around 1.75 mm in diameter, is introduced into the vein under local anesthesia. The vein is treated directly by the energy transmitted by the laser shots to the internal venous wall, which is heated radially, homogeneously and precisely along the vein’s length. The vein is not removed; it disintegrates and is then eliminated by the body within a few months.
Single use RING probes, compatible with any laser
SEDI-ATI provides disposable fiber probes, called “RING”, which are intended for single use only: one probe for one intervention.
Our RING probes are compatible with any 1470 nm endovenous laser available on the market. Indeed, we are able to integrate the laserist’s own handpiece on the probe. In addition, we add a centimeter marking on the jacket to help the surgeon visualize how much length of fiber has been introduced into the vein.
RING: design and testing
The RING probe has a glued encapsulated tip that is smooth and atraumatic to prevent perforation of the vein wall. It has been successfully tested in traction up to 17 kg after the “beef test” where it had to conduct 5 kJ laser energy until carbonization of the end tip.
The RING probe is available with different fiber sizes of 400 µm, 550 µm and 600 µm, allowing to treat both the great and the small saphenous veins. All these models feature a homogenous and extremely precise radial emission of the laser energy, ensuring effective destruction of the varicose vein.
