Systems and method for controlling the bending of a robotic catheter. A control backbone of the robotic catheter is coupled to a linear movement stage by a spring and linear movement of the control backbone causes a controllable bending of the robotic catheter. A sensor monitors a deflection of the spring and the bending of the catheter is controlled based on the spring deflection signal from the sensor. The spring allows passive bending of the robotic catheter without movement of the active linear movement stage and, conversely, allows external forces applied to the robotic catheter to limit a bending movement of the robotic catheter caused by&#x2014;movement of the active linear movement stage. In some implementations, the robotic catheter includes a selectively deployable tip mechanism for deploying a steerable tip or for selectively exposing side windows on the catheter for increasing traction for clot removal.
