ABSTRACT:
An elongate elastic metal alloy member for use in a medical device. The elongate member may be formed from a linear elastic metal alloy which may be twisted such that the torsional elasticity of the member is removed while the longitudinal flexibility of the member is maintained. The elongate member may further be placed under tension, fixed to prevent rotation, and heat treated such that the stress caused by tensioning and twisting the member is relieved without transforming the linear elastic metal alloy into a superelastic metal alloy. The resulting elongate elastic metal alloy member may have increased straightness and may be easier to grind.
