Laser structured fibre optic tip for minimally invasive laser therapy

In venous disorders, radial-emission optical fibers play a key role in developing laser-tissue interaction therapies due to their biocompatibility, flexibility and compactness. A novel customized laser-based method for manufacturing fiber tips with protective glass caps is developed by IZM. The geometry of tips can be defined by a cone, wedge, among others. In particular, conical-structured tips show an efficient radial beam profile in comparison to other types of optical tips and they can also be used in hard-to-access zones.
