An implant, in particular an intraluminal endoprosthesis, or a semi-finished part for an implant, having a hollow cylindrical body, wherein the body includes magnesium, and the body is enriched with gallium or a gallium alloy in a region close to a surface.

Implant and method for production thereof

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 (), wherein the semifinished article contains magnesium or a magnesium alloy, the method comprising preparing the semifinished article (), and shaping the semifinished article at a temperature of between 250&#xb0; C. and 550&#xb0; 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.

A method for producing a semifinished part () for an implant, in particular for an intraluminal endoprosthesis, which comprises the following steps:

Implant and method for producing the same

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.

Implant and method for producing a degradation-inhibiting layer on the surface of an implant body

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.

Stent made of nitinol having improved axial bending stiffness and associated production method

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.
