Abstract
An elongate flexible plastic tubing includes a helical support bead, and defines a central passage opening on opposite ends of the tubing. The tubing may also include one or more lumens extending helically in the support bead from end to end of the tubing. Also, the tubing may include one or more electrical conductors also extending helically from end to end of the tubing. Additionally, one or plural fiber optic conductors may extend helically from end to end of the tubing. The lumen(s), electrical conductors, and fiber optic conductors, are available for utilization to, for example: conduct electricity, carry out electrical resistance heating of fluid flow in the central passage, carry electrical signals, carry fluid, transmit fluidic signals, or to convey light, and/or optical signals, along a length of the tubing.
