The application relates to an elongated torque tube for use in medical applications. The torque tube comprises an elongated tubular structure having a cylindrical cross section and defining a longitudinal axis and a circumferential axis, the elongated tubular structure including a helical cut having a finite thickness and extending along the length of the elongated tubular structure, the helical cut being aligned with the circumferential axis and including a plurality of protrusions (402) extending along the longitudinal axis, the protrusions defined by discontinuous cuts (404,410) aligned with the longitudinal axis.
