ABSTRACT:
To protect the launch surfaces of laser catheters fed with short-pulsed laser radiation, the individual optical fibers are placed on the launch side in hexagonally closest packing. Ablation-resistant materials are applied to the outer circumference of the cross-section area adjacent to the launch device, and the individual fibers and the ablation-resistant materials are connected to one another by material or friction connections. The ablation-resistant materials are of the same material, silicate, or PTFE, as the optical fibers.
