Abstract: Inducing thrombolysis of thermally induced thrombus occurring during endovenous ablation of varicose veins by introducing an optical fiber laser deliver device with optical fiber portion and with an energy emitting tip at its distal end into the varicosed vein to be treated, emitting pulsed, laser energy with sufficient energy to close and destroy varicose veins to the emitting tip of the optical fiber laser delivery device, thereby inducing laser thrombolysis of coagulated blood which accumulates at the energy emitting tip of the fiber when the fiber is caused to emit energy in the presence of uncoagulated blood and minimizing adverse effects associated with thermally induced thrombus within a varicose vein.

Abstract: Method and device for the detection of caries, plaque, calculus, bacterial attack, etc. in/on teeth, a radiation being generated using a light source and directed at a tooth to be examined, producing a reflected radiation there. The reflected radiation is detected and evaluated using a detection device. Advantageously, the tooth is irradiated using two or more wavelength ranges, the measured reflected intensities of the two wavelength ranges being related to one another as a characteristic value for the presence of caries, plaque, calculus, bacterial attack. As a supporting measure, the fluorescence radiation may also be evaluated.

Abstract: A fiber optic radiation transmission system is provided in which an optical fiber and a radiation source are connected to establish optical communication therebetween. Additionally, a connecting system is provided for connecting an optical fiber and a radiation source such that optical communication is established therebetween. The systems include a connector which carries the optical fiber therein. The connector is extendable within the system toward the radiation source to bring the optical fiber into optical communication with the radiation source. More particularly, the systems are configured in such a way that when the connector is extended sufficiently within the system, it seats the optical fiber relative to the radiation source under bias, thereby establishing a reliable optical connection. Once the optical connection is thus established, the connector engages a connection port associated with the radiation source to secure the system in a fully connected configuration appropriate for use.
