    摘要: The present invention relates to a method for manufacturing an implant, in particular an intraluminal endoprosthesis, having a body containing metallic material, preferably iron. For controlling the degradation of the implant the method includes the following steps: (a) providing a first part of the implant body; and (b) performing heat treatment which alters the carbon content and/or the boron content and/or the nitrogen content in the structure of a near-surface boundary layer in the first part of the implant body in such a way that strain on the lattice or a lattice transformation, optionally following a subsequent mechanical load, is achieved in the near-surface boundary layer. Such an implant is also described.

    摘要: A medical supporting implant, in particular a stent, comprises a tubular base body which is made up of bendable struts (2), such that at node points (4) of at least two struts (2), the bendable struts (2) form an acute angle (W) to one another which angle becomes larger on dilatation of the implant with plastic deformation of the struts (2) at the node point (4). At least a portion of the struts (2) between the plastic deformation areas (4) is provided with a telescoping ratchet mechanism (R) for irreversible lengthening of the respective struts (2) on dilatation.

    摘要: A stent made of nitinol having improved axial or radial stiffness, the stent having a support structure which comprises peripheral struts around the circumference, wherein the peripheral struts are linked to one another in the axial direction via connection struts. The support structure may assume a first compressed state and a second expanded state. The nitinol is in the support structure in a martensitic microstructure in the compressed state and largely in an austenitic microstructure in the second expanded state. One or more support structure sections, however, are entirely or partially in a martensitic microstructure in the second expanded state.
