Input device for controlling a catheter
An input device includes a plurality of orientation blocks each representing a portion of a catheter assembly and a controller configured to determine an orientation of the plurality of orientation blocks relative to one another. The controller is further configured to output a control signal that causes a tip of a catheter assembly to adopt the orientation determined by the controller. A system includes an actuator configured to manipulate a position and orientation of the catheter assembly. The controller of the input device is configured to output a control signal to the actuator to make a tip of a catheter assembly adopt the orientation determined by the controller. The input device can be virtually represented on a computing device.
