  • Publication number: 20110094566
    Abstract: A luminescence concentrator (LK) may concentrate both incident direct and diffuse light by way of frequency shift and total internal reflection. It differs fundamentally from geometric concentrators. With sufficient geometric expansion of the collector plate, nearly arbitrarily high concentration can be achieved in the LK. A luminescence disperser is an apparatus which holds both directional and nondirectional incident light captive in a transparent body by way of frequency shift and total internal reflection and emits it diffusely or directionally uniformly distributed across an area by way of luminescence emission. The object of the invention is a method for the technical implementation of the LK and luminescence disperser, using zeolite crystals having a nanotube structure, into which the luminescent dyes are embedded such that they have antenna properties. Using the resulting novel structures, problems can be solved which made the technical use of LK impossible or at least considerably limited it.

  • Publication number: 20100121423
    Abstract: The invention relates to a stent that comprises a single sinus section and is preferably provided at the proximal end thereof with a native vessel valve (26). The stent comprises a first and a second hollow-cylindrical section (10, 11) having a first and a second diameter each, and a third section (12) disposed therebetween having a third maximum diameter. The third maximum diameter is greater than the first and second diameters and forms the sinus section. The stent according to the invention with the single sinus has an increased functionality. Particularly when used with a graft with a sinus and vessel valve, the functionality of the stent is secured and the wear is diminished. The stent is particularly suitable for native valves and particularly as a pulmonary valve replacement.
