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.
