Abstract
A medical apparatus includes a probe, which includes an insertion tube configured for insertion into a body cavity of a patient and a basket assembly connected distally to the insertion tube and including a plurality of resilient, conductive spines, which are configured to contact tissue within the body. The apparatus further includes an electrical signal generator configured to apply between one or more pairs of the spines bipolar pulses having an amplitude sufficient to cause irreversible electroporation (IRE) in the tissue contacted by the spines.
