    Abstract: The systems and methods of the present disclosure are used for guiding a medical instrument towards a target, the method positioning a medical instrument at a first location within a patient anatomy, wherein the medical instrument comprises at least one sensor, determining a first biomarker measurement using the at least one sensor, determining a second biomarker measurement using the at least one sensor, comparing the first biomarker measurement with the second biomarker measurement to determine a proximity to the target to provide a first comparison, and providing guidance for moving the medical instrument based on results of the first comparison.

    Abstract: A surgical instrument is provided that includes a first input mechanism having axial slots formed in a periphery and a second input mechanism having helical slots formed in a surface. The instrument also includes an insert having pins extending from a surface thereof, the insert coupled to the second input mechanism such that the one or more pins extend into the helical slots, and a surgical device coupled to an end. The surgical device is moved in a first degree of freedom in response to a mechanical driving force applied to both the first input mechanism and the second input mechanism, respectively, and the surgical device is moved in a second degree of freedom in response to a mechanical driving force applied to the second input mechanism while the first input mechanism is held stationary.

    Abstract: A minimally-invasive surgical system includes a slave surgical instrument having a slave surgical instrument tip and a master grip. The slave surgical instrument tip has an alignment in a common frame of reference and the master grip, which is coupled to the slave surgical instrument, has an alignment in the common frame of reference. An alignment error, in the common frame of reference, is a difference in alignment between the alignment of the slave surgical instrument tip and the alignment of the master grip. A ratcheting system (i) coupled to the master grip to receive the alignment of the master grip and (ii) coupled to the slave surgical instrument, to control motion of the slave by continuously reducing the alignment error, as the master grip moves, without autonomous motion of the slave surgical instrument tip and without autonomous motion of the master grip.
