  • Publication number: 20110319986
    Abstract: A method for producing an implant, particularly an intralumimal endoprosthesis, having a body, wherein the body comprises magnesium or a magnesium alloy. In order to control the degradation in a desired time window, such as between four weeks and six months, the following production method is carried out: a) preparing the implant body, b) applying a metallic coating onto at least a portion of the body surface, the primary constituent of the coating being at least one element of the group containing titanium and aluminum, c) plasmachemical treatment of the portion of the body surface provided with the coating in an aqueous solution in order to produce a layer created by plasmachemical treatment by applying a mixed voltage generating the plasma to the body of the implant, wherein the mixed voltage has sufficient energy to temporarily ionize both the metallic coating and a subjacent region of the implant body. The invention further relates to an implant that can be obtained by such a method.

  • Publication number: 20080033535
    Abstract: A stent having a structure made of a biocorrodible metallic material, having multiple web sections connected to one another, with a support structure made of a number of first web sections connected to one another, designed to assume a function supporting the vascular wall or preserving the mechanical integrity of the stent for a predefinable time after expansion; and at least one second web section electrically connected directly to a first web section of the support structure, which does not assume a function supporting the vascular wall or preserving the mechanical integrity of the stent for the predefined time after the expansion, and whose electrode potential E2 is reduced by a mechanical strain of the second web section during or before the expansion so it is lower than an electrode potential E1 of the first web section after the expansion.

  • Patent number: 6899914
    Abstract: A method of applying a marker element (6; 6?; 6?; 25; 25?; 26; 28) to an implant (1; 1?; 1?; 1??; 20; 20?), in particular a stent, intended for implantation in the human or animal body, comprising a main body and an opening (3; 3?; 3?; 3??; 21; 21?) provided in said main body (2; 2?; 2?; 2??; 22; 22?) for receiving the marker element (6; 6?; 6?; 25; 25?; 26; 28), wherein to form at least a part of the marker element (6; 6?; 6?; 25; 25?; 26; 28) a hardenable material or material mix is introduced into the opening and hardened therein.
