Description

[0001] This is a Continuation-in-Part of U.S. patent application Ser. No. 10 / 409,559 filed Apr. 8, 2003. Priority is claimed on that application and on the following application:

[0002] Country: Germany, Application No. 03002905.2, filed Feb. 10, 2003

[0003] The present invention relates to an improved metal alloy for medical implants or devices for desired material properties. BACKGROUND OF THE INVENTION

[0004] A medical implant or device must satisfy a number of requirements. Factors affecting the choice of the medical implant or device and the material thereof are mainly all mechanical properties and biocompatibility. The material must not cause any inflammatory reaction or allergic reaction. Commonly used materials often include nickel, like medical grade 316L stainless steel, which contains about 16% nickel. For patients with an allergic reaction the implantation of such materials is contraindicated. Another consideration in material selection is the need for the implanting phys...
