    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.

    Abstract: A medical system comprises a catheter having a first section, a second section and a main lumen extending through the first and second sections. The system also includes an imaging probe sized to extend through the main lumen of the catheter. The system also includes a first electromagnetic sensor extending along a longitudinal sensor axis at a proximal end of the first section and a second electromagnetic sensor extending along the longitudinal sensor axis at a distal end of the first section. The first section between the proximal and distal ends flexibly couples the first and second electromagnetic sensors so that the first electromagnetic sensor is movable with respect to the second electromagnetic sensor. The system also includes a third electromagnetic sensor positioned on the imaging probe and a fiber shape sensor system that extends through the first section between the proximal and distal ends and along the first electromagnetic sensor and the second electromagnetic sensor.
