1. A control for a medical device, the control comprising:
- a body;
an actuator coupled to the body via a shaft and including a trigger, wherein the actuator is configured to move relative to the body in a first direction and a second direction, the movement in the first direction corresponding to rotating the actuator about an axis defined by the shaft, and the movement in the first direction being independent of the movement in the second direction;
at least one first control member coupled to the actuator and configured to move when the actuator is moved in the first direction to deflect a distal end of the medical device in a first plane;
at least one second control member coupled to the actuator and configured to move when the actuator is moved in the second direction to deflect a distal end of the medical device in a second plane; and
at least one third control member coupled to the trigger for actuating an end effector of the medical device;
wherein at least one of the first control member or the second control member has an inner member and an outer sheath each having a first end and a second end, the inner member and the outer sheath arranged such that the first ends of the inner member and the outer sheath move with respect to one another when the actuator is moved in one of one of the first direction or the second direction and do not move with respect to each other when the actuator is moved in the other of the first direction or the second direction.

Abstract
A control system for allowing a user to control the orientation of a medical device or a medical instrument in a variety of directions. An actuator selectively tensions one or more control cables having ends secured at or adjacent a distal tip of the medical device in order to bend the distal tip in a desired direction. In one embodiment, a physician can adjust the movement of the distal tip in a desired direction without affecting the orientation of the medical device in other directions.

12. A control for a medical device, the control comprising:
-
a body; an actuator coupled to the body via a shaft and including a trigger, wherein the actuator is configured to rotate relative to the body about a first axis and a second axis, the shaft defining one of the first axis or the second axis, and the rotation about the first axis being independent of the rotation about the second axis; at least one first control member mechanically coupled to the actuator and configured to move when the actuator is rotated about the first axis to deflect a distal end of the medical device in a first plane; at least one second control member mechanically coupled to the actuator and configured to move when the actuator is rotated about the second axis to deflect a distal end of the medical device in a second plane; and at least one third control member mechanically coupled to the trigger for actuating an end effector of the medical device; wherein at least one of the first control member or the second control member has an inner member and an outer sheath each having a first end and a second end, the inner member and the outer sheath arranged such that the first ends of the inner member and the outer sheath move with respect to one another when the actuator is rotated about one of the first axis or the second axis and do not move with respect to each other when the actuator is rotated about the other of the first axis or the second axis. - View Dependent Claims (13, 14, 15)

16. A control for a medical device, the control comprising:
-
a body; an actuator coupled to the body via a shaft and including a trigger, wherein the actuator is configured to rotate relative to the body about a first axis and a second axis, the rotation about the first axis being independent of the rotation about the second axis, and wherein the shaft defines the first axis or the second axis; at least one first control member mechanically coupled to the actuator and configured to move when the actuator is rotated about the first axis to deflect a distal end of the medical device in a first plane; at least one second control member mechanically coupled to the actuator and configured to move when the actuator is rotated about the second axis to deflect a distal end of the medical device in a second plane; at least one third control member mechanically coupled to the trigger for actuating an end effector of the medical device; and a trunnion including a slot that receives a guide plate; wherein at least one of the first control member or the second control member has an inner member and an outer sheath each having a first end and a second end, the inner member and the outer sheath arranged such that the first ends of the inner member and the outer sheath move with respect to one another when the actuator is rotated about one of the first axis or the second axis and do not move with respect to each other when the actuator is rotated about the other of the first axis or the second axis. - View Dependent Claims (17, 18, 19, 20)
