Abstract
A catheter and associated positioning system can include sensors and software to ascertain the extent of expansion of an expandable distal member of the catheter. Sensors on the distal member can be configured so that the system is able to determine a longitudinal dimension and a radial dimension of the distal-end assembly and determine extent of expansion of the distal member based on those metrics. At least the longitudinal dimension can be derived from advanced current localization (ACL) techniques utilizing an electrode at a distal end of the expandable distal member.
