Abstract: A pull wire attachment system for a minimally invasive medical instrument comprises an anchoring element fixedly attached to the medical instrument. The anchoring element has a first outer diameter. The system also includes a pull wire assembly comprising an elongate pull wire having a proximal end and a distal end and a securing element coupled to the distal end of the pull wire. The securing element includes a second outer diameter sized smaller than the first outer diameter of the anchoring element. The securing element is coupled to the anchoring element to prevent proximal translation of the distal end of the pull wire along a longitudinal axis of the medical instrument past the anchoring element.

Abstract: A biopsy system includes a biopsy tool and a control system in communication with the biopsy tool. The control system is configured to receive a command to perform a biopsy, retrieve a predefined dynamic trajectory for performing the biopsy from a memory device, and control the biopsy tool to move according to the predefined dynamic trajectory to perform the biopsy. The predefined dynamic trajectory includes a plurality of dynamic control modes. Each of the plurality of dynamic control modes has a different displacement profile. At least one different displacement profile comprises a cyclic displacement profile.

Abstract: A medical instrument system includes an imaging probe and an elongated medical instrument. The imaging probe includes a first sealing feature comprising a first tapered profile formed on an external surface of the distal tip. The elongated medical instrument has a working channel extending to an opening in the distal portion. The distal portion includes a second sealing feature comprising a second tapered profile formed on an internal surface of the channel. A distal end surface of the distal tip extends through the opening and distally of a distal end surface of the elongated medical instrument when the first sealing feature is engaged with the second sealing feature. The first tapered profile and the second tapered profile form a seal that prevents fluid from passing through the opening when the imaging probe is within the working channel of the elongated medical instrument and the first and second sealing features contact.

Abstract: Systems and methods for integrated real-time visualization while performing a minimally invasive procedure within anatomic passageways include a flexible catheter having one or more first lumens and a first positioning system, an imaging probe having one or more imaging elements, and a scaling device. In souse embodiments, the scaling device includes a plurality of second lumens and the flexible catheter and the imaging probe are each optionally deployed through a respective one of the second lumens. In some embodiments, the one or more imaging elements include one or more ultrasound transducers. In some embodiments, the scaling device seals the anatomic passageways at a scaling location using one or more balloons, and the anatomic passageways distal to the sealing location are collapsed. In some embodiments, the first positioning system includes one or more position sensors. In some embodiments, the procedure is performed after the passageways are collapsed.

Abstract: A pull wire attachment system for a minimally invasive medical instrument comprises an anchoring element, a steerable tube, and a pull wire assembly. The anchoring element comprises a hollow tube having a first outer diameter. The pull wire assembly comprising a pull wire having a proximal end and a distal end and a securing element coupled to the distal end. A portion of the pull wire is disposed within a groove having an open cross-sectional shape extending along a length of the steerable tube. The securing element includes a second outer diameter sized smaller than the first outer diameter. The securing element is coupled to the anchoring element to prevent proximal translation of the distal end of the pull wire along a longitudinal axis of the medical instrument past the anchoring element. A proximal end of the securing element is disposed distal to a distal end of the steerable tube.

Abstract: An apparatus may include an instrument including an elongated shaft and a shape sensor including an elongated optical fiber extending within the elongated shaft at a first radial distance from a neutral axis. The apparatus may also comprise a reference sensor disposed within the elongated shaft. The shape sensor may be fixed in a known first position relative to the reference sensor. The apparatus may also comprise a twist resistant feature disposed within the elongated shaft. The twist resistant feature may be coupled to the shape sensor to reduce twisting of the elongated optical fiber relative to the elongated shaft while permitting axial translation of the elongated optical fiber within the elongated shaft. The shape sensor may be coupled to the twist resistant feature at a known second position relative to the reference sensor.
