The World’s Smallest Endovascular Laser. The neoV1470 is a superb microsurgical instrument for endovenous laser ablation of veins, as well as for incision and excision of soft tissue in critical areas. The peak of water absorption at 1470nm enables precise cutting with good coagulation of soft tissue. As a result of this unique tissue absorption, procedures can be completed at lower energy dosages leading to less thermal trauma and better healing.
