Abstract
Tubing comprising a tubing wall formed of an elongate thermoplastic ribbon helically wrapped and heat bonded to itself to form the tubing wall. The tubing may include one or more elongate conductors helically wrapped around and along the tubing wall. The tubing may include an elongate reinforcement rib helically wrapped around and along the tubing wall such that the tubing wall includes a first portion in which the elongate reinforcement rib covers the one or more elongate conductors and a second portion in which the one or more elongate conductors are uncovered by the elongate reinforcement rib and the elongate reinforcement rib wraps around the tubing wall.

Tubing comprising:
- a tubing wall having a length and formed of an elongate thermoplastic ribbon continuously helically wrapped and heat bonded to itself to form the tubing wall;
- one or more elongate conductors helically wrapped around and along the tubing wall;
- and
- an elongate reinforcement rib continuously helically wrapped around and along the tubing wall such that the tubing wall includes a first portion in which the elongate reinforcement rib covers the one or more elongate conductors and a second portion in which the one or more elongate conductors are uncovered by the elongate reinforcement rib and the elongate reinforcement rib wraps around the tubing wall, the first portion being adjacent to the second portion along the length of the tubing wall.
