Abstract
A medical apparatus includes a probe, which includes an insertion tube configured for insertion into a body cavity. A balloon is connected distally to the insertion tube and is inflated within the body with a fluid that flows into the balloon through the insertion tube. Electrodes are disposed at different respective locations on a surface of the balloon and configured to contact tissue within the body cavity, each electrode being divided into multiple segments, including at least two segments having different respective areas. An electrical signal generator applies radio-frequency (RF) signals simultaneously in parallel to the multiple segments of each electrode with an amplitude sufficient to ablate the tissue contacted by the electrode. Sensing circuitry acquires electrophysiological signals from at least one of the multiple segments of each electrode separately and independently of the other segments of the electrode.
