A method of performing a medical procedure (e.g., a cardiac bypass procedure) on a patient comprises introducing at least one medical instrument into a patient (e.g., percutaneously), conveying control signals from a remote controller to a drive unit, and operating the drive unit in accordance with the control signals to actuate at least one tool respectively located on the medical instrument(s) to transversely secure a first anatomical vessel (e.g., a blood vessel) to a sidewall of a second anatomical vessel (e.g., another blood vessel). In one method, the control signals are conveyed from the remote controller to the drive unit in response to user commands. The user commands may be movements made at a user interface that correspond to movements of the medical instrument(s).

The method of claim 1, wherein the control signals are conveyed from the user input device to the drive unit in response to user commands. 3. The method of claim 2, wherein the user commands are movements made at the user input device that correspond to respective movements of the second medical instrument and the third medical instrument. 4. The method of claim 1, wherein the second medical instrument is percutaneously introduced within the patient. 5. The method of claim 1, wherein the second medical instrument and the third medical instrument are introduced into the patient by operating the drive unit in accordance with the respective control signals. 6. The method of claim 1, wherein the first anatomical vessel is a blood vessel. 7. The method of claim 1, wherein the medical procedure is a cardiac bypass procedure. 8. The method of claim 1, wherein each of the first and second active tools comprises respective first and second suturing or sewing tools, and the drive unit is operated in accordance with the control signals to actuate the first and second suturing or sewing tools in unison to transversely secure the second anatomical vessel to the sidewall of the first anatomical vessel. 9. The method of claim 1, further comprising: operating the drive unit in accordance with the control signals to actuate a third tool located on the first medical instrument to hold a lumen of the second anatomical vessel open while transversely securing the second anatomical vessel to the side wall of the first anatomical vessel. 10. The method of claim 9, wherein the third tool is a balloon that is inflated within the second anatomical vessel to hold the lumen open. 11. The method of claim 1, further comprising: introducing a fourth medical instrument within the second anatomical vessel; andoperating the drive unit in accordance with the control signals to actuate a third tool located on the fourth medical instrument to create an opening within the side wall of the first anatomical vessel. 12. The method of claim 11, wherein the third tool is a cutting blade that is operated to cut an opening through the side wall of the first anatomical vessel. 13. The method of claim 11, further comprising: introducing a fifth medical instrument within the first anatomical vessel; andoperating the drive unit in accordance with the control signals to actuate a fourth tool located on the fifth medical instrument to hold the side wall of the first anatomical vessel in place while creating the opening within the side wall of the first anatomical vessel. 14. The method of claim 13, wherein the fourth tool is a balloon that is inflated within the first anatomical vessel where the opening is to be formed within the sidewall to hold the side wall in place. 15. The method of claim 14, the balloon of the fourth tool being inflated across the opening to be formed within the sidewall. 16. The method of claim 14, the balloon of the fourth tool being positioned adjacent to the opening to be formed before the opening is formed. 17. A method of performing a medical procedure on a patient involving a first anatomical vessel and a second anatomical vessel that is to be transversely secured to the first anatomical vessel, the method comprising: positioning a first remotely computer-controlled medical instrument within the second anatomical vessel, wherein the first medical instrument is sufficiently flexible so as to be capable of being remotely controlled and maneuvered through a curvature of an elongated portion of the second anatomical vessel, and wherein the first medical instrument comprises a first expandable member;inflating the first expandable member within the second anatomical vessel that is to be attached to a sidewall of the first anatomical vessel such that the first expandable member applies pressure to an inner surface of the second anatomical vessel;manipulating a user input device to robotically control movement of the first medical instrument in order to position the second anatomical vessel adjacent to the sidewall of the first anatomical vessel;attaching the second anatomical vessel to the sidewall of the first anatomical vessel;positioning a second remotely computer-controlled medical instrument within the first anatomical vessel, wherein the second medical instrument is sufficiently flexible so as to be capable of being remotely controlled and maneuvered through a curvature of an elongated portion of the first anatomical vessel, and wherein the second medical instrument comprises a second expandable member;inflating the second expandable member within the first anatomical vessel such that the second expandable member applies pressure to an inner surface of the first anatomical vessel; andforming an opening within the sidewall of the first anatomical vessel while the second expandable member applies pressure to the inner surface of the first anatomical vessel. 18. The method of claim 17, the second expandable member being inflated adjacent to the location of the opening to be formed. 19. The method of claim 18, wherein the first expandable member is inflated at a position within the second anatomical vessel that is proximal and not adjacent to the location of the opening to be formed at a distal end of the second anatomical vessel such that the inflated first expandable member does not contact the sidewall of the first anatomical vessel. 20.
