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 first material is present in an amount not greater than 9% by volume based on the combined volume of the first material and the second 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. |
