  • Publication number: 20190151067
    Abstract: An arrangement for storage of a self-expanding stent-like device includes a container for storing the stent-like device and a stent delivery system arranged at the container and including an outer tube and an inner shaft axially moveable relative to the outer tube. The container includes an interior space and one stent passage opening. A distal end of the outer tube is connected to the stent passage opening. An insertion part of ring-like shape is located at the stent passage opening. The inner shaft extends through the insertion part and includes a retainer to prevent the stent-like device from axial movement relative to the inner shaft. When the stent-like device is stored in the interior space of the container, a proximal end of the stent-like device is compressed to a diameter smaller than a diameter of the insertion part and is held radially compressed by the insertion part.

  • Patent number: 10088403
    Abstract: A method and a device that determines surface characteristics of a stent to be implanted in a lumen in a body in which a wetting behavior of a stent surface serves as measure for the surface characteristics of the stent surface. In order to determine the wetting behavior, a course of a wetting force along a length of the stent surface is determined, the wetting power between the stent surface and a liquid surface being detected along the length of the stent.

  • Patent number: 8904846
    Abstract: A device and a method for providing a stent for implantation into a body lumen are provided, wherein the stent (3) has a proximal end (31) and a distal end (32), between which a stent lumen having a compressible diameter d extends. The device comprises a crimping apparatus (4), having elements (40) which are disposed about an axis and can be moved at least partially relative to each other radially to the axis, and an activator (42) for actuating the crimping apparatus (4). The elements (40) of the crimping apparatus comprise the stent (3) and can be moved radially by means of the activator (42) from a widened position, in which the stent (3) is not crimped, into a closed position, in which the diameter d of the stent (3) is compressed.

  • Patent number: 8584852
    Abstract: The system according to the present disclosure includes a metal stent (3) as a medical implant for treating lesions in blood vessels and a packaging (1) having an inside volume, in which the stent (3) is arranged in a protected manner. The stent (3) has a plurality of webs (33), which produce a tubular shape with each other, and a proximal end (31) and a distal end (32), between which a stent lumen (34) extends. The stent surface (35) has a hydrophilic property. The molecular chemical impurities originating in the atmosphere, primarily hydrocarbon compounds, are significantly reduced on the surface by a treatment, whereby the contact angle as a measure of the hydrophilicity of a water drop present on the surface (35) is reduced in proportion to the contact angle prior to said treatment. The stent (3) is stored in an inert manner in the packaging (1).
