1. A method for making a tubular body, comprising:

  • directing a primary mandrel along a central axis of a braiding apparatus such that the primary mandrel is surrounded by a plurality of reinforcement carrying elements in a predetermined configuration relative to the central axis;

    providing an elongate conductor dispenser at a first location adjacent to the reinforcement carrying elements and offset from the central axis;

    with a conductor feeding from the dispenser at the first location, simultaneously wrapping reinforcement members from the reinforcement carrying elements and wrapping the conductor from the dispenser helically around a first portion of the primary mandrel;

    moving the dispenser to a second location;

    with the conductor feeding from the dispenser at the second location, wrapping reinforcement members from the reinforcement carrying elements helically around a second portion of the primary mandrel while the conductor extends substantially axially along the second portion;

    applying an outer jacket around the primary and secondary mandrels after wrapping the one or more reinforcement members therearound; and

    removing the primary mandrel to define a primary lumen within the tubular body.
