Triangel, a leading manufacturer and the world‘s No. 1 producer of Endolaser systems, is proud to announce its latest innovation in vascular care: a high-precision 980nm + 1470nm dual-wavelength diode laser specifically engineered for Endovenous Laser Ablation (EVLT). This cutting-edge platform delivers unparalleled safety and efficacy for the minimally invasive treatment of venous insufficiency.
The new system leverages the synergistic power of two clinically proven wavelengths. The 1470nm laser is uniquely absorbed by water, the primary chromophore in venous wall tissue. This enables precise, homogeneous thermocoagulation of the vein with lower energy requirements, significantly minimizing post-operative pain and bruising for patients. Concurrently, the 980nm wavelength provides excellent hemostasis and tissue interaction, ensuring a controlled and efficient procedure.
Our dual-wavelength technology represents a significant advancement in phlebology. By combining the optimal tissue interaction of 980nm with the water-specific targeting of 1470nm, we offer vascular surgeons a tool that not only achieves durable vein occlusion but also enhances patient comfort. We are committed to providing solutions that set the gold standard of phlebology through precision engineering.
Clinical studies have consistently validated the efficacy of 1470nm EVLT. A recent systematic review and meta analysis demonstrated excellent mid-term and long-term outcomes, with truncal vein occlusion rates reaching approximately 93% at two years and 89% at five years. The review also highlighted the importance of linear endovenous energy density (LEED) in optimizing these results, a critical parameter that Triangel‘s intuitive operating system helps clinicians manage effectively.
The Triangel EVLT system is designed with the modern vascular specialist in mind. Key features include:
Dual-Wavelength Versatility: Offers 980nm for effective coagulation and 1470nm for gentle, water-specific venous closure, allowing surgeons to tailor energy delivery to individual patient anatomy.
Enhanced Safety Profile: By targeting water within the vein wall, the 1470nm wavelength reduces the risk of perforation and thermal damage to surrounding tissues, such as nerves, leading to faster recovery times.
Compatibility with Advanced Fibers: The system is fully compatible with radial emitting fibers, which ensure 360-degree uniform energy delivery for consistent and reliable vein sealing.
