摘要：
Metallic stents which have a randomly oriented microstructure, and possess quasi-isotropic mechanical and physical properties are disclosed. The novel stents can be “tailor-made” to mimic the geometry of the blood vessel(s) at the deployment site and can be designed to treat coronary artery disease at the point where blood vessels branch. The metallic materials of choice are ductile, corrosion resistant and exhibit little crystallographic texture. The novel stents can be produced from a metallic precursor which is quasi-isotropic and exhibits little texture by processing means, such as machining, which do not reintroduce texture. Alternatively, quasi-isotropic and low texture stents are achieved by suitable post-processing of conventionally fabricated stent materials.
