Abstract
A method includes receiving position signals that are indicative of positions of multiple electrodes disposed on an expandable balloon that is fitted at a distal end of a shaft for engaging a lumen of an organ to occlude the lumen. Based on the received position signals, a change is calculated in one or more dimensions of the balloon between (i) a first configuration in which the balloon is inflated but not engaged in the lumen, and (ii) a second configuration in which the balloon is inflated and engaged in the lumen. Using the calculated change, a degree is estimated to which the balloon occludes the lumen. The estimated degree of occlusion is presented to a user.
