Methods using a robotic catheter system
First Claim
1. A method using robotic catheter system to perform a procedure on a patient, comprising:
- generating a control signal corresponding to movement of a master input device; and
moving a plurality of drive elements of an instrument driver in response to the control signal, the drive elements operatively coupled to a corresponding plurality of control elements of an elongate guide instrument, the control elements secured to a distal end of the guide instrument and moveable axially relative to the guide instrument such that movement of the drive elements causes a corresponding movement of the guide instrument distal end, wherein the control signal causes individual ones of the plurality of drive elements to move independently of one another in order to achieve a desired bending of the guide instrument distal end.
