    Abstract: The present invention relates, generally, to controlling a steerable instrument having an elongate body. More particularly, the present invention relates to a system and method for sensing the shape of a steerable instrument and controlling the steerable instrument in response to a control signal from a user input device and a shape signal corresponding to the sensed shape of at least a portion of the steerable instrument. The present invention also relates to a system for sensing the shape of a flexible instrument with an optical shape sensor.

    Abstract: A medical instrument may comprise a first articulatable segment having a first diameter, and a second articulatable segment having a second diameter smaller than the first diameter, wherein the second articulatable segment is coupled to the first articulatable segment and extends in a distal direction past the first articulatable segment. The instrument may also comprise a first force transmission element coupled to the first articulatable segment and extending in a proximal direction from the first articulatable segment to a first connector portion, the first connector portion being configured to be releasably coupled with a first actuator, and a second force transmission element coupled to the second articulatable segment and extending in a proximal direction from the second articulatable segment to a second connector portion, the second connector portion being configured to be releasably coupled with a second actuator. The first and second force transmission elements may be configured to transmit actuation forces, respectively, to articulate the first and second articulatable segments independently of one another.

    Abstract: The cross section of a curved portion of a curved cannula is oval shaped. The oval is oriented such that a major axis of the oval is generally aligned with the curved portion's bend radius. In one aspect, the cannula tube is ovalized so that the radius of curvature of an interior wall approaches the outer radius of an instrument component that contacts the curved portion during instrument insertion. In this first aspect, a wider contact patch area between the instrument component and the cannula results, which reduces friction and stick-slip during insertion. In another aspect, the cannula tube is ovalized so that the radius of curvature of an interior wall is less than the outer radius of an instrument component that contacts the curved portion during instrument insertion. In this second aspect, two contact patches are established between the instrument component and cannula, which also reduces friction and stick-slip during instrument insertion. Also disclosed is a cannula orientation marking that changes circumferential orientation along a length the curved cannula to help a person who is inserting the cannula to properly twist the cannula during insertion.
