1. A metallic wire, comprising:
- an outer cylindrical shell of a first biocompatible metal; and
a plurality of wire elements disposed within said shell, at least one of said wire elements including an outer tubing of a second biocompatible metal filled with a core of a third biocompatible metal, said outer shell and said plurality of wire elements compacted together such that substantially no voids exist within said outer shell.

Abstract
A wire for use in medical applications. The wire is formed by forming a bundle from a plurality of metallic strands and positioning the bundle within an outer tube. The tube and strands are then drawn down to a predetermined diameter to form a wire for use in medical devices. The wire may be covered with an insulating material.

12. A method of making a metallic wire, said method comprising the steps of:
-
providing an outer cylindrical shell of a first biocompatible metal, the shell having a first outer diameter; inserting a plurality of wire elements into the outer shell to form a wire construct, at least one of the wire elements including an outer tubing of a second biocompatible metal with the outer tubing filled with a core of a third biocompatible metal; and drawing the wire construct to form a drawn wire of reduced diameter with the outer shell having a second outer diameter less than the first outer diameter, and the plurality of wire elements being compacted together such that substantially no voids exist within the outer shell. - View Dependent Claims (13, 14, 15, 16, 17)
