Abstract:
1. A method for making a conduit for transmitting signals along its length, comprising the steps of: equipping a tubular body with a communicative coupler at or near an end of the tubular body; positioning an elongated pad at or near an inner wall of the tubular body; extending one or more conductive wires along the pad such that the one or more wires are disposed between the inner wall of the tubular body and at least a portion of the pad; connecting the one or more wires to the communicative coupler so as to establish a wired link; and securing the elongated pad to the tubular body by positioning an expandable tubular sleeve within the tubular body such the pad is disposed between the tubular body and the expandable sleeve; and plastically expanding the expandable sleeve into engagement with the tubular body, whereby the pad is secured between the expandable sleeve and the tubular body.
