摘要：
The invention relates to an elongated interventional device (1), configured to receive an optical shape sensing fiber (9) and comprising (i) an elongated proximal section (22) including at fixation element (24) at its proximal end, the fixation element (24) being connectable to a reception (25) at a predetermined location (3) and (ii) an elongated distal section (21) connected to the proximal section (22). The proximal section (22) has a lower torsion stiffness than the distal section (21) and comprises at least two substantially co-axial tubes, the outer tube having a lower torsion stiffness than an inner tube. Thus, the elongated interventional device (1) can be affixed to the predetermined location in order to determine its shape and position by means of optical shape sensing without affecting the devices maneuverability, particularly with respect to rotational movements of the distal section (21).
