In one aspect the invention provides a surgical implant conductor formed from a length of conductive material which exhibits increased radio frequency alternating current resistance. This conductive material defines an exterior surface where at least a portion of the exterior surface of the conductor defines a region with a roughened surface. Preferably the roughening of the exterior surface increases the area of the exterior surface when compared to a non-roughened surface, resulting in a reduction in the effective cross-section area of the conductor used to transport alternating currents.
