Abstract
A method of forming a surface structure of a component of a medical devices includes forming a fatigue-resistant portion, which entails forming a first layer comprising a transition metal selected from the group consisting of Ta, Nb, Mo, V, Mn, Fe, Cr, Co, Ni, Cu, and Si on at least a portion of a surface of the component, where the surface comprises a nickel-titanium alloy, and alloying the transition metal of the first layer with the nickel-titanium alloy of the surface. The method further includes forming a rough outer surface of the fatigue-resistant portion where the rough outer surface is adapted for adhesion of a material thereto.
