ABSTRACT:
A flexible tube structure includes a coil assembly including a plurality of coils which are combined together in such a manner that turns of the plurality of coils alternate with each other. Any two adjacent turns of the plurality of coils are disposed in substantially point-to-point contact relation to each other. There is also disclosed a bending device in which an operating wire is passed through at least one axially-extending space formed between peripheries of the plurality of coils. A distal end of the operating wire is fixed relative to a distal end of the coil assembly.
