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.

What is claimed is: 1. A method of performing a medical procedure using a coaxial catheter arrangement including an outer catheter having a proximal balloon, and an inner catheter having a distal balloon, the method comprising the steps of: a) introducing the coaxial catheter arrangement within an anatomical vessel of a patient; b) inflating the proximal balloon to anchor the outer catheter within the anatomical vessel; c) after inflating the proximal balloon, linearly translating the inner catheter relative to the outer catheter within the anatomical vessel in the distal direction; d) after linearly translating the inner catheter relative to the outer catheter, inflating the distal balloon to anchor the inner catheter within the anatomical vessel; e) after inflating the distal balloon, deflating the proximal balloon to release the outer catheter from the anatomical vessel; f) after deflating the proximal balloon, linearly translating the outer catheter relative to the inner catheter within the anatomical vessel in the distal direction; and g) after linearly translating the outer catheter relative to the inner catheter, deflating the distal balloon to release the inner catheter from the anatomical vessel, wherein the steps b) to g) are performed automatically. 2. The method of claim 1, further comprising repeating the foregoing steps to cause incremental movement of the coaxial catheter arrangement within the anatomical vessel. 3. The method of claim 1, wherein an electric controller is used to direct an electromechanical driver to linearly translate the outer and inner catheters relative to each other and a balloon controller for inflating and deflating the proximal and distal balloons. 4. The method of claim 1, further comprising conveying at least one command to the electric controller via a user interface. 5. The method of claim 1, further comprising actuating an articulating tool on the inner catheter within the anatomical vessel. 6. The method of claim 1, wherein the anatomical vessel is a blood vessel.
