Composite material endoprosthesis |
摘要 |
An endoprosthesis includes a body structure formed of a biocompatible material, the body structure including a first material having an average atomic number greater than 24 and a second material that is different than the first material. The body structure has a mass absorption coefficient effective to provide a ratio of an intensity of an incident X-ray to an intensity of a transmitted X-ray in a range of 1e<-2> to 1e<-4>. The endoprosthesis may have a yield strength not greater than 100,000 psi. The endoprosthesis may be in the form of a wire or a tube. In one embodiment the first material is present in an amount not greater than 9% by volume based on the combined volume of the first and second materials. In another embodiment, about 30 to about 40% by volume of the first material is present based on a combined volume of the first and second materials in an endoprosthesis of tubular form. |
