Abstract

A medical apparatus includes a probe, which includes an insertion tube configured for insertion into a body cavity of a patient, and a distal assembly, which is connected distally to the insertion tube and includes a plurality of electrodes, which are configured to contact tissue within the body cavity. The apparatus further includes an electrical signal generator, which is configured to apply electrical pulses to a group of two or more of the electrodes with an amplitude sufficient to irreversibly electroporate the tissue contacted by the electrodes in the group, and a controller, which is coupled to measure a change in an electrical impedance between an electrode in the group and a further electrode as a result of application of the electrical pulses and to output a measure of ablation of the tissue responsively to the measured change in the electrical impedance.
