A coiled tubing system includes a length of coiled tubing, a cable and an inner tube. The inner tube and the cable are installed in the coiled tubing, and then either the coiled tubing or the inner tube or both are deformed along most of the length of the system so that the cable is secured between the inner surface of the coiled tubing and the outer surface of the inner tube. The coiled tubing and the inner tube may be coaxial, with the cable situated in the annulus between the coiled tubing and the inner tube. The deformation may be produced by a swaging die introduced into the inner tube, the application of a high pressure fluid or gas, crimping the outer surface of the coiled tubing, or using an inner tube reversibly deformable through the application of tension. Similarly, a conducting member may be secured in a system with a length of coiled tubing and an inner tube. Also, a cable or a conducting member may be installed upon an inner tube which may then be removed.
