  • Patent number: 10893932
    Abstract: An implant having a preferably hollow cylindrical basic structure. A nonwoven fabric is disposed in and/or on the basic structure, the nonwoven fabric preferably comprising biocompatible thermoplastic polyurethane and/or a polymer selected from the group consisting of polylactic acid, polycaprolactone, and a copolymer thereof, and/or a polymer including polyphosphazene. At least in at least one section of the implant, preferably at the proximal and/or distal ends of the implant, fastening means are provided or the nonwoven fabric is treated such that, at least in the expanded state of the implant, the protrusion of nonwoven fabric sections from the implant is significantly reduced. Furthermore, a method for producing such an implant is provided.

  • Patent number: 10775671
    Abstract: A display device includes a light emitter comprising a set of light emitter portions, wherein at least one light emitter portion of the set is configured to emit light with an excitation wavelength, and a color conversion layer including a set of conversion layer portions. At least one conversion layer portion of the set comprises a film comprising a solid polymer composition that includes luminescent crystals of perovskite structure, which are selected from compounds of formula (I): M1aM2bXc (I), wherein M1 represents Cs, M2 represents Pb, and X independently represents anions selected from the group consisting of Cl, Br, I, cyanide, and thiocyanate. The luminescent crystals are of size between 3 nm and 3000 nm, and emit light of a wavelength in response to excitation by the light emitted by at least one corresponding light emitter portion of the set, wherein the excitation wavelength is shorter than the wavelength.
