Abstract

A method of manufacturing a kink resistant sheath includes the steps of coating a wire with a plastic material to form an inner tube, placing a braid over the inner tube, applying a spring reinforcement over the braid and applying a second layer of plastic material over the assembly to form an outer tube of a braided reinforced sheath. The plastic material is preferably polyurethane but may be a thermoplastic, thermoset or any plastic material having hard and/or soft durometer.
