Abstract

A method for performing a medical procedure, consisting of providing a probe, having a known spring constant, for insertion into a patient, the probe having electrodes and a position sensor at respective locations along the probe, and recording relative location coordinates of the electrodes and the position sensor when the probe is in an unrestrained state. While the probe is in the patient and deformed by contact with patient tissue, recording changes in the relative location coordinates of the electrodes in contact with the tissue and the position sensor, and computing a probe shape in a deformed state, in response to the recorded changes. In response to the known spring constant and the computed probe shape, computing a respective force exerted by the tissue on each of the electrodes, and controlling electrical signals through the electrodes from the tissue responsively to the computed respective force on the electrodes.
