Zusammenfassung:A system may comprise a flexible delivery device including a tool channel extending therethrough and an elongated instrument configured to extend within the tool channel. The elongated instrument may include a flexible section and a rigidizable section. The system may also include a selective rigidization system at least partially extending within the elongated instrument and a sensor system configured to determine position information for the rigidizable section relative to a distal portion of the delivery device. The selective rigidization system, responsive to the position information, may be configured to transition a portion of the rigidizable section of the instrument from a bendable state to a rigid state.
