EndoVenous Laser Treatment (EVLT)

LSO Medical launches the LUMESEAL, First platform in the world integrating Snakeback® technology !
LSO R&D Team is proud to announce the completion of its development work on its new laser platform: LUMESEAL

The LUMESEAL is the world first laser platform to integrate the Snakeback® technology.
The Snakeback® technology, developed and patented in 2018 by the company LSO Medical, is a Plug&Treat Operating Room designed system, to perfectly standardize and assist Physicians during EVLT procedure. 

Thanks to its unique conception, the SnakeBack® technology ensures an automatic removal of the catheter, without the need for catheter tension or device alignment with the leg to be treated. The patented technology SnakeBack module appears as the next generation of the actual pull-back devices, bypassing their constraints.

The integration of this technology on the LUMESEAL platform has made it possible to consider and develop new technical specifications, simplifying and optimizing current procedures.

Surpassing human performance in its control of speeds and movements, but also in movement / delivery synchronization, LUMESEAL must also make it possible to make a major contribution to scientific work in the field, and become a must. On the one hand, it makes it possible to overcome the variability of the operator, but also to make a direct correlation between the recording of the energy delivery profile carried out along the vein, and the result of the intervention.

On the other hand, it also makes possible the study of new operating protocols, hitherto impossible by manual removal.

The Endotherme™ 1470 laser & Ringlight® radial Fibers
Resulting from a great technological outcome, LSO Medical proposes the Endotherme™ 1470 & its Ringlight® fibers, which guarantee at the same time:
  • optimal efficacy,
  • long-term occlusion rate
  • optimized post-operative comfort
The Ringlight® fiber emits a radial emission that leads to a homogenous destruction of the vein wall.
Thanks to the design of its tip, the Ringlight® fiber allows a safe introduction of the fiber into the vein to treat.

The LSO Medical's Endotherme™ 1470 laser offers 2 exclusive features:
  • Back Reflection : this exclusive asset allows to detect a potential variation of the signal emitted during the laser treatment. For each procedure and each fiber, the "Back Reflection" system guarantees the efficiency and safety of the laser shot. it also allows immediate detection of a potential drop in laser power, without having to wait for annual maintenance, guaranteeing the correct functioning of the Laser in the long run.
  • Smartcart : offers traceability for every procedure, all treatment data (power, LEED, energy delivered, etc.) are automatically saved on the smartcard. These data can be downloaded and saved on the computer using a card reader and a program provided by LSO Medical
According to current international recommendations, both the Endotherme™ 1470 and Lumeseal offer a 1470 nm wavelength with radial firing fibers. 

EndoVenous Laser Treatment (EVLT) : A cutting-edge technology to treat varicose veins

The endovenous laser is integrated into the management of chronic venous insufficiency, by treating varicose veins.  These varicose veins treatment is a mini-invasive and ambulatory procedure, performed under echo-guidance based on endovenous thermo-occlusion. 

Endovenous laser treatment is based on a thermal effect, which occurs onto the vein wall. The thermal effect is induced by the light (wavelength 1470 nm), leading to parietal modifications, causing the occlusion of the incompetent saphenous vein: 
  • alteration of the endothelium
  • contraction of the collagen
The vein fibrosis is instantly visible under echo-guidance, and the complete and long-term occlusion occurs within weeks. 

EndoVenous Laser Treatment (EVLT) indications
EndoVenous Laser Treatment (EVLT) allow physicians to treat every incompetent vein:
  • Great Saphenous veins
  • Small saphenous veins
  • Perforating veins
  • Accessory veins
  • Veins with diameter from 4 mm, up to 20 mm

Fibers & Disposables

LSO Medical designs, manufactures and provides a wide variety of optical fibers
LSO Medical offers multiple patented manufacturing processes:
  • Fiber types: Radial / Distal
  • Radial tips: Glued / Fused 
  • Sizes: 600 µm / 440 µm / 400 µm
Ringlight® fibers in Endovenous laser Treatment (EVLT)
The Ringlight® fiber emits a radial emission that leads to a homogenous destruction of the vein wall.
Thanks to the design of its tip, the Ringlight® fiber allows  a safe introduction of the fiber into the vein to treat.

Ringlight® fiber - 6 references: 
- Rrinlight_SB 600 µm : comptabible Lumeseal with Snakeback® module
- Rrinlight_SB 400 µm : comptabible Lumeseal with Snakeback® module
- Ringlight - Standard 600 µm : Ø1.8 mm 
- Ringlight - Slim 400 µm : Ø1.0 mm
- Ringlight Fused - Standard 600 µm : Ø1.8 mm
- Ringlight Fused - Slim 440 µm : Ø1.3 mm

LSO Medical provides all of the equipments and disposables needed for the EVLT procedures.
Tumescence pump & tubing disposables
  • The tumescent pump is used to perform the tumescent anesthesia by avoiding many successive handlings
  • Possibility of continuously adjusting the infiltration speed
  • The pump is used with sterile tubing disposables

Introducer kits
The introducer kits contain : 
  • one short introducer (11 cm) with a dilatator
  • one guide-wire J.018" x 45 cm
  • one straight needle 21G x 7 cm
The introducer kits are available in two references :
  • 4F : compatible with the "Slim" Ringlight® Fiber
  • 6F : compatible with the "Standard" Ringlight® Fiber
Direct access catheter
  • The 16G catheters are compatible with the "Slim" Ringlight® Fibers, practical for the treatment of fine and superficial veins
  • The 16G catheter allows direct access, without the use of the introducer kit

Exotherme™ is a transcutaneous vascular laser, indicated for the occlusion and disappearance of superficial vascular lesions from 0.2 to 2 mm diameter (red, blue, purple colored telangiectasias). 


The principle of the Exotherme™ laser is based on the thermal action of the laser, resulting from the conversion of laser light energy into heat. The 980nm wavelength emitted by the laser is strongly absorbed by hemoglobin. Hemoglobin transfers heat to the vessel walls.  This effect makes the closure and the destruction of the vessel possible. 

A High-tech Laser

The Exotherme Laser has a unique handpiece, the Control 4+, combining several innovative technologies :
- The Multipulse Technology, that guarantees a clinical efficacy and a tissue safety for a pain -free treatment. 
- The integrated camera and the optical zoom, that provides real-time visualization for a precise treatment.
- The self-regulated cooling system at 5°C, that guarantees a painless treatment.
- The trans-illumination diodes, to improve the visualization of the deeper vessels. 

A simple procedure 

The procedure is simple, efficient, quick and safe. The number of sessions varies between each patient. The results appear gradually and are permanent 4 to 6 weeks after the treatment.
