1. An apparatus for manufacturing atherectomy torque tubes, comprising:

  • means for winding a wire around a tube liner with a selected pitch and wire separation to provide a wound tube;

    means for applying a coating onto said wound tube at a rate which generates a thickness of material to establish an outside diameter for said tube;

    means for providing a signal representing a desired outside diameter;

    means for measuring said outside diameter of said coated tube and generating a signal representative of an amount of deviation of said measured diameter from said desired diameter; and

    control means coupled to said coating means and said winding means for varying said rate of application of said coating to attenuate said deviation signal, while maintaining said selected pitch and wire separation on said tube.
