  • 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: 9005265
    Abstract: A stent made of a material having a low strength and having a main body circumscribing a cylindrical shape and radially expandable from a contracted starting position into a dilated support position, comprising a) a plurality of support segments disposed around the circumference and arrayed on one another in the axial direction each segment being formed by a strut meandering in its coarse structure in its contracted starting position and having alternately opposing meandering curves expandable into the support position made of flexible material; b) a plurality of axial connectors connecting between zenith points of at least a part of the meandering curves in the axial-parallel direction of the support segments; (c) a plurality of x-ray marker projections, and d) at least one stabilizer for stabilizing the strut coarse structure in its contracted starting position against radial expansion and being automatically detachable upon radial expansion.

  • Publication number: 20090270977
    Abstract: A stent fixation system 3 for fixation of a stent, comprising two retaining areas 10 which are connected by a connecting area 12 to form a fixation tubing. The retaining areas 10 provide a retaining structure which is designed to hold at least one stent strut 2 of the stent in the undilated state, such that the stent struts 2 are no longer in one of the retaining areas 10, at least in the dilated state of the stent.
