Abstract
A system includes secondary and primary catheters, and a processor. The primary catheter includes shaft for insertion into an organ of a patient, first position sensor disposed on a distal end of the shaft, expandable assembly coupled at the distal end of the shaft, the assembly comprising hollow channel to allow passage of the secondary catheter distally via the assembly, and plurality of second position sensors disposed along a distal end of the secondary catheter, which are configured to indicate a respective plurality of positions along its distal end. The processor is configured to receive the indications of the positions, apply a model of known mechanical properties of the distal end of the secondary catheter to the positions to compute bending profile of the secondary catheter inside the assembly, and based on the computed bending profile, estimate orientation of the assembly relative to the distal end of the shaft.
