Abstract

A method includes positioning an expandable balloon, coupled to a distal end of a catheter, at a target location within an organ of a patient, the expandable balloon including multiple electrodes and one or more sensors in proximity to each electrode, wherein the one or more sensors are configured each to measure a characteristic of blood. The expandable balloon is expanded at the target location. A fluid is flowed through an inner lumen of the catheter and into the blood in a vicinity of each electrode. A dependence of the characteristic of blood on time is measured, via the one or more sensors, in proximity to each electrode. Using a processor, it is determined whether or not each electrode is in physical contact with tissue, based on the measured dependence of the characteristic of blood. An indication of whether or not each electrode is in physical contact with tissue is outputted to a user.
