A robotic medical system and method of performing a medical procedure are provided. The robotic medical system comprises a user interface configured for receiving commands, an electromechanical driver configured for being coupled to outer and inner catheters having proximal and distal balloons, a balloon controller configured for being coupled to the proximal and distal balloons, and an electric controller configured for directing the electromechanical driver to linearly translate the outer and inner catheters relative to each other and for directing the balloon controller to inflate and deflate the proximal and distal balloons in response to the command(s). The method may comprise inflating and deflating the proximal and distal balloons, and linearly translating the inner and outer catheters relative to each other in a specified sequence to move the inner and outer catheters along the anatomical vessel.
