Abstract

A system includes a catheter and a processor. The catheter includes (i) a shaft for insertion into a cavity of an organ of a patient, (ii) an expandable distal-end assembly coupled to a distal end of the shaft and comprising splines fitted with spline-electrodes, (iii) a proximal position sensor and a respective proximate proximal electrode located both at a proximal end of the distal-end assembly, and (iv) an independent wire that extends at the distal tip, with a distal position sensor and a respective proximate distal electrode located both at a distal end of the independent wire. The processor is configured to estimate locations of one or more of the spline-electrodes by performing impedance measurements on the one or more of the electrodes, and to calibrate the impedance measurements based on signals received from the proximal position sensor and the distal position sensor and the respective proximal and distal electrodes.
