Various wires and methods of making the same are disclosed. In one aspect, a wire is provided that includes a core and a tube around the core. The tube is composed of an alloy containing about 33 to 37% nickel, about 31.5 to 39% cobalt, about 9 to 10.5% molybdenum, and about 19 to 21% chromium. The wire has an ultimate tensile strength of about 150 to 250 kpsi, an amount of cold work following a final anneal and a torsional ductility of greater than about 6 turns-to-failure per inch of the wire.

High torsional ductility wire and methods of making the same

Metal composite tubes offer advantages in constructing biomedical device components such as stents. The composite tube comprises a cylindrical wall made of a biocompatible metal matrix with a filament or filaments of other metals that add radiopacity, and/or other advantageous mechanical or physical properties. The filaments are generally oriented along the length of the tube and are surrounded by the wall of the tube.
