Abstract: A flexible attachment assembly is described having a bellows capable of absorbing torsion having a first end; a second end opposite to the first end; and a plurality of tubes, each of which is hollow and wound around a longitudinal axis while extending from the first end to the second end, where the plurality of tubes are communicated with each other all along the longitudinal length of the bellows so as to form a bore between the first end and the second end. Also provided is a bellows assembly having at least two sections, each section having a plurality of tubes, each of which is hollow and wound around a longitudinal axis and thus form a bore, where the plurality of sections are connected with each other so that their bores are communicated.
