Abstract: What is described is a minimally invasive system comprising an elongate instrument and a stylet slidably disposed within the lumen of the elongate instrument. The instrument includes a flexible proximal portion fixedly coupled to a rigid distal portion, and a lumen extending from a proximal end to a distal end through the flexible proximal portion and the rigid distal portion and defining a longitudinal axis of the instrument. The stylet includes a flexible body fixedly coupled to a steerable portion and a sensor element extending through the flexible body. The stylet is movable within the instrument between a retracted condition in which the steerable portion is retracted within the instrument and an extended configuration in which the steerable portion at least partially extends from the rigid distal portion of the instrument.

Abstract: A minimally invasive system comprises an elongate instrument that includes a flexible proximal portion, a rigid distal portion, and a lumen extending from a proximal end to a distal end of the elongate instrument. The lumen defines a longitudinal axis of the elongate instrument. The flexible proximal portion is fixedly coupled to the rigid distal portion. The system further comprises a stylet slidably disposed within the elongate instrument. The stylet includes a flexible body fixedly coupled to a steerable portion and includes a sensor. The stylet is movable within the elongate instrument between a retracted condition and an extended configuration. A plurality of actuation cables extend through the stylet and terminate in the steerable portion, which comprises a bend-resistive section and a bendable section. The bendable section includes a plurality of articulable segments linked by the actuation cables and includes a plurality of joint pivots disposed between adjacent articulable segments.
