Robotic medical instrument system
First Claim
1. A method of performing a medical procedure on a patient, comprising:
- introducing a stent into an anatomical vessel of the patient;
introducing a first medical instrument and a second medical instrument into the patient, the first medical instrument being located outside of the anatomical vessel, the second medical instrument being located within the anatomical vessel and within an inner space defined by the stent, a distal end of the first medical instrument comprising a first active tool configured to pierce the anatomical vessel and the stent, the second medical instrument comprising a second active tool configured to receive a stitch delivered by the first active tool and extending through the anatomical vessel and the stent;
conveying control signals from a remote controller to a drive unit; and
operating the drive unit in accordance with the control signals to actuate the first and second active tools in unison to pierce a wall of the anatomical vessel, pierce the stent, and secure the stent to an inner wall of the anatomical vessel using the stitch.

Abstract
A method of performing a medical procedure on a patient comprises introducing a 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 the tool located on the medical instrument to secure a stent to an anatomical vessel (e.g., a blood vessel, such as an abdominal aorta). The tool may be a sewing tool that is controlled to stitch the stent to the anatomical 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.
