1. A method for providing a deformable substrate, comprising the steps of:
- a) providing the substrate comprising an alloy including at least one of cobalt, molybdenum, and chromium;
b) covering at least a portion of the substrate with an elastomeric material; and
c) coating an intermediate carbonaceous material on at least a portion of the substrate between the substrate alloy and the elastomeric material to thereby prevent interaction of the at least one of cobalt, molybdenum, and chromium of the substrate alloy with the elastomeric material.

Abstract
Implantable electrical lead wires, such as cobalt-chromium-molybdenum alloy wires, are coated with a metal, ceramic, or carbon to a thickness of about 100 nm or less to provide a non-reactive interface to polyurethane sheathing materials. Preferred is sputter coating an amorphous carbon intermediate the alloy wire and the polyurethane sheath.
