For thermal ablation of saphenous veins
After the success of the Pharaon 980 nm and following the validation of the clinical interest of the 1470 nm wavelength, LSO Medical launched the 1470 nm Endotherme™ in 2012.
This wavelength of 1470 nm combined with its “continuous” firing mode are now recognized as the Gold Standard in the thermal ablation treatment of saphenous by laser.
Why the wavelength 1470 nm?
a) Selective energy delivery
The Endotherme™ 1470 laser emits infrared light with a wavelength of 1470 nm.
Emitted inside the saphenous, the light is thus absorbed by the water (its chromophore) of the venous wall and then converted into heat.
Under the effect of this heat, the venous wall is destroyed, which leads to the occlusion of the saphenous.
b) Focused energy delivery
The penetration distance of the wavelength 1470 is of the order of 300 to 400 μm. During thermal endovenous treatment, the 1470 laser acts on more than half the thickness of the venous wall (thickness between 450 and 600 μm), inducing a level of tissue damage necessary (to induce the destruction of the vein) and sufficient (not to induce damage in the adjacent compartment).
c) Conclusion
Wavelength Diode Laser 1470 nm + Radial Emission Fibers:
Low light penetration (0.34mm) by WL 1470 nm
Light oriented towards the venous wall by the radial emission fiber
Short exposure time (thanks to continuous shrinkage)
=> Destruction of the Wall without destruction of surrounding tissues or nerves
Laser Endotherme™ 1470 – Indications
The precise targeting of the 1470 nm Endovenous Laser allows a high precision of the treatment as well as wide indications.
The Endovenous Laser is indicated for:
- Large saphenous veins (between 4 and 20 mm in diameter in orthostatic position)
- Small saphenous veins (between 4 and 20 mm in diameter in orthostatic position)
- And their associated complementary acts:
- Accessory saphenous
- Perforating veins
Endotherme™ 1470 should not be used in the following cases:
Patients with thrombi in the venous segment intended for treatment.
Patients with an aneurysm in the venous segment intended for treatment.
Patients with peripheral vascular diseases with an ankle-arm systolic pressure index below 0.9.
Patients with deep vein thrombosis or with a history of deep vein thrombosis.
Pregnant patients.
Patients with infection on the area to be treated, active herpes or other viral infection.
Other contraindications may be indicated by the practitioner at the time of treatment.
