1. A method comprising:
wrapping a filament around an elongate medical device substrate to thereby form a distinct thread of wrapped filament, wherein the wrapped filament has a variance along the elongate medical device substrate in one or more of a wrapping pitch, a filament density, a filament thickness, a filament material composition, and a filament cross-sectional shape; and
melting the wrapped filament to thereby form at least a portion of the elongate medical device having a property that varies in accordance with the variance in the wrapped filament.
