Abstract
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.
