    Abstract: A medical system may comprise a catheter that includes an elongate body and a main lumen extending longitudinally through the elongate body. The medical system may also comprise a vision probe that includes a tube extendable through the main lumen of the catheter and comprising a flexible body having an outermost wall and an innermost wall, the innermost wall defining a central lumen. The flexible body contains a plurality of channels formed within the flexible body of the tube and separated from the central lumen by the innermost wall. The plurality of channels includes oblong channels for irrigation and suction and auxiliary channels. The oblong channels have concentric arc shaped surfaces forming an arcuate channel cross-section. The auxiliary channels have a different shape than the one or more oblong channels. The vision probe also includes an imaging system and illumination fibers running through respective auxiliary channels in the tube.

    Abstract: A guiding apparatus comprises a support assembly extending along a longitudinal axis. The support assembly includes a first plurality of linkages including a first channel formation, a second plurality of linkages including a second channel formation, and a strut having a proximal portion and a distal portion. The distal portion of the strut is coupled to the support assembly. The support assembly has a coupled configuration with a proximal end and a distal end in which the first plurality of linkages is coupled to the second plurality of linkages with the first and second channel formations arranged to form a continuous channel through the support assembly. The continuous channel has an elongated opening sized to receive an elongated flexible instrument in a direction generally perpendicular to the longitudinal axis.

    Abstract: An apparatus includes a reference fixture. The reference fixture includes a joint, and a joint tracker to track motion of the joint. The apparatus also includes a surgical instrument. A tether is connected between the joint and the surgical instrument. A shape sensor extends from the reference fixture through the joint, through the tether, and into the surgical instrument. The shape sensor is substantially free of twist. The joint tracker measures the motion of the joint. Information from the shape sensor in combination with information from the joint tracker provides absolute three-dimensional information relative to the reference fixture, i.e., provides absolute three-dimensional information in a fixed world reference frame.
