Device Story

Diode laser therapy device generates 980nm and 1470nm laser wavelengths for soft tissue surgical applications. 980nm wavelength used for incision, excision, vaporization, ablation, hemostasis, and coagulation; 1470nm wavelength targets water molecules for treatment of saphenous vein reflux. Device operates in contact or non-contact modes; includes temperature monitoring system. Physician-operated in clinical settings. Laser light delivered via fiber optic; output controlled by user (continuous, pulse, or single modes). Aiming beam (650nm) assists positioning. Clinical benefit includes precise tissue management and minimally invasive vein treatment. Device output affects surgical site directly; clinical decision-making guided by physician assessment of tissue response.
