摘要:
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.
摘要:
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.
摘要:
A method for producing a semifinished part (20) for an implant, in particular for an intraluminal endoprosthesis, which comprises the following steps: a) providing a first sleeve (11) from a first metallic material and at least one second sleeve (12, 13) from a second metallic material, b) arranging the first sleeve (11) and the at least one second sleeve (12, 13) into one another in such a manner that the sleeve combination (10) forms at least a press fit between said sleeves, and c) forming the sleeve combination (10) at an increased temperature by means of extrusion. The invention further includes a method for producing an implant, to a corresponding semifinished part or a corresponding implant, respectively.

摘要:
A semifinished product for an implant and implants produced from the semifinished product, the semifinished product comprising or consisting of a region of a magnesium alloy, which is characterized by a grain size gradient of the magnesium alloy between two opposed surfaces from ≦3 μm to ≧8 μm, in each case in relation to the average grain size. Use of the semifinished product for producing corresponding implants, and also a method for producing semifinished products.
