The application relates to an elongated torque tube (200) 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 (202) having a finite thickness and extending along the length of the elongated tubular structure, the helical cut being oriented along the circumferential axis and including a plurality of flexural units (204) defined by discontinuous cuts aligned with the circumferential axis. |
