“…167,168,190 Further investigation also showed wavelength-dependent discrepancies. 186,191 These effects are clearly related to the wavelength-dependent optical properties of vein tissue and blood 189 and were confirmed by MC simulations. [182][183][184][185] Heat induction (T ¼ 85°C for 30 s) of the vein tissue samples showed a swelling of the sample concomitant with shrinkage in length.…”

“…Variations in the laser wavelength, power settings, and irradiance result in different temperature levels and thermal alterations up to perforation. 182,183,[186][187][188] As blood is the primary medium around the laser fiber tip, it influences the mechanism and the alteration process as well, especially in cases where carbonization is induced. 162,164,181,189 Initially, laser energy was applied by using bare fibers emitting coaxially in the vessel lumen.…”

Medical laser applications based on widespread research and development is a very dynamic and increasingly popular field from an ecological as well as an economic point of view. Conferences and personal communication are necessary to identify specific requests and potential unmet needs in this multi- and interdisciplinary discipline. Precise gathering of all information on innovative, new, or renewed techniques is necessary to design medical devices for introduction into clinical applications and finally to become established for routine treatment or diagnosis. Five examples of successfully addressed clinical requests are described to show the long-term endurance in developing light-based innovative clinical concepts and devices. Starting from laboratory medicine, a noninvasive approach to detect signals related to iron deficiency is shown. Based upon photosensitization, fluorescence-guided resection had been discovered, opening the door for photodynamic approaches for the treatment of brain cancer. Thermal laser application in the nasal cavity obtained clinical acceptance by the introduction of new laser wavelengths in clinical consciousness. Varicose veins can be treated by innovative endoluminal treatment methods, thus reducing side effects and saving time. Techniques and developments are presented with potential for diagnosis and treatment to improve the clinical situation for the benefit of the patient.
