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.

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 CFlayer that is nonpolymerized and has an F/C ratio in the range of 0.5 to 1.5.

Implant with a base body of a biocorrodible alloy

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.

Stent

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

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.

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.
