An OSS guiding and monitoring system employs an interventional device (40) including an integration of a OSS sensor (20) and one or more interventional tools (30), the OSS sensor (20) for generating shape sensing data informative of a shape of the OSS sensor (20) as the interventional device (40) is navigated within an anatomical region. The OSS guiding and monitoring system further employs an OSS guiding controller (90) for controlling a reconstruction of a shape of the interventional device (40) within the anatomical region responsive to a generation of the shape sensing data by the OSS sensor (20), and an OSS monitoring controller (100) for controlling a monitoring of a degree of folding and/or a degree of twisting of the interventional device (40) within the anatomical region.
