  • Patent number: 9913707
    Abstract: A method for producing an implant and the implant itself, particularly an intraluminal endoprosthesis, wherein the implant is produced from a preferably hollow cylindrical semifinished article (10), wherein the semifinished article contains magnesium or a magnesium alloy, the method comprising preparing the semifinished article (10), and shaping the semifinished article at a temperature of between 250° C. and 550° C. using a tool, which has a metallic lubricant containing gallium and/or a gallium compound on at least a part of its surface that will come into contact with the semifinished article.

  • Patent number: 8801778
    Abstract: An implant having a base body, comprised either entirely or in part of a biocorrodible metallic material wherein at least the parts of the base body having the biocorrodible metallic material are at least partially covered with a coating of a crosslinked CFx layer that is nonpolymerized and has an F/C ratio in the range of 0.5 to 1.5.

  • Patent number: 8728611
    Abstract: A stent comprises a metallic, relatively radiolucent carrier structure and at least one marker element which includes comparatively radiopaque material. The radiopaque material is completely enclosed by a cover layer of a material other than the radiopaque material, the cover layer including metal or a metal compound. The stent may be used to treat a patient.

  • Patent number: 8603569
    Abstract: A method for manufacturing a degradation-inhibiting first layer on the surface of an implant body, in particular an intraluminal endoprosthesis, whereby the body has at least one metallic material, which is at least largely biodegradable, comprising the following steps: preparing the body of the implant, and applying the first layer to at least a portion of the body surface, whereby the first layer contains magnesium stearate. An implant obtainable by such a method.

  • Patent number: 8110088
    Abstract: The present invention relates to a method for manufacturing an implant, in particular an intraluminal endoprosthesis, with a body containing metallic material, preferably iron. To control the degradation of the implant, the method comprises the following steps: a) preparing the body of the implant, and b) incorporating hydrogen into at least a portion of the structure of the implant body near the surface. Furthermore, such an implant is described.

  • Patent number: 7862606
    Abstract: The invention relates to stents made of a material with an elongation at rupture of 30% or less and with a tubular base body which entirely or in parts comprises structural segments which are interconnected in longitudinal direction of the stents by means of transverse connectors and in which the structural segments comprise a zigzagging or undulating structure of a brace which is wrapped around the longitudinal axis of the stent. Due to the mechanical properties of the materials used, adaptation of the stent design is required. This is achieved in that in a turning region of the zigzagging or undulating structure the brace comprises a straight bending section aligned in circumferential direction.

  • Publication number: 20100145432
    Abstract: The present invention describes a method for producing an implant, in particular an intraluminal endoprosthesis, wherein the base material of the body (5) of the implant has biodegradable metallic material, preferably Mg or an Mg alloy. The method comprises the following steps: a. Provide the body (5) of the implant, b. Apply a first layer (10), which contains Ca ions and P ions, to at least a part of the surface of the body (5) and c. Apply a second layer (20), which is at least partially permeable for Ca ions and P ions, such that this at least largely covers the first layer (10). Furthermore, a corresponding implant is described, in which the degradation behavior can be controlled through the production according to the invention.
