Embodiments of the present invention provide an internally threaded tube
of virtually limitless length that can be easily and reliably
constructed. In one aspect, the invention provides an internally threaded
tube that includes a tube casing and a coil. A ratio of the length of the
tube casing to the inner diameter of the tube casing can be greater than
5:1. The coil can be positioned coaxially within the tube casing. In this
position, the coil can exert a radially outward force on the inner
surface of the tube casing, which can aid in bonding. A portion of the
coil can be specially adapted to be bonded to the tube casing. Methods of
creating internally threaded tubes and methods of spirally delivering
surgical components with internally threaded tubes are also disclosed.
